▼ Introduction:-Development of modern automated machines in industries has considerably decreased the physical burden of workers in addition to increasing the productivity of the industries resulting in noise pollution. Noise exposure above the limit value of 90 dB (A) is known to cause temporary hearing loss among exposed workers. Objective: - To assess temporary hearing loss, associated factors and measuring noise levels among workers in textile factory Q. Methods and materials: - A cross-sectional study design was employed from January 15 to April 30, 2019. The data collection methods were observational checklist, self-administered questionnaire and aerial and personal noise level measurements. Department heads and environmental health proffesionals was participated for data collection. A total of 406 using computerized simple random sampling and 27 individuals using Homogenous Exposure Groups were included respectively for the self-adminstered questionnaire and personal noise exposure measurements. Data was entered using Epi-data version 4.2 and analyzed using SPSS version 21. Also 95% confidence interval was calculated for the independent variables and P value <0.05 had included to show the significance of the association. Results: - The questionnaire was completed by 388 (95.6% response rate) production section workers, of which 254 (65.5%) were females and 134 (34.5%) were males. About One hundred ninty (49.0%, COR=1.53; 95% CI= [1.15-2.03]) workers reported that they have at least one temporary hearing loss problems during working time in the textile factory. None of the participants reported the use of hearing protective devices and maximum LAeq, noise levels were recoeded in spinning II, 89.1+5.9 dBA and knitting, 89+4.3dBA. There was significant association between working departments and temporary hearing loss of workers. Conclusion: - The presented study demonstrated that work force in the spinning and knitting departments of the textile factory had high prevalence of temporary hearing loss. Recommendations: - The textile factory should implement control measures such as engineering and administrative (rotation of workers) controls with providing hearing protective devices to reduce the noise exposure among workers. 8hr Advisors/Committee Members: Dr.Kumie, Abera (MD, MSc, PhD.)

Masters Research - Master of Philosophy (MPhil)

This research investigated the experiences of Australian employees with hearing impairment who communicate orally in the workplace. Using mixed methods research, one hundred and fifty-nine people with hearing impairment responded to a sixty-one item online questionnaire, fifteen people participated in one of three focus groups and three people participated in an in-depth interview. The online questionnaire collected demographic information of the cohort and solicited information on the individual’s use of assistive technologies, experiences accessing workplace modifications, discrimination and knowledge of Australian Government support programs. The focus groups set out to gather additional qualitative context to the responses from the online questionnaire on the experiences of employees requesting workplace modifications, the value of supportive colleagues and illuminative descriptions of a workplace utopia - an environment that employees believed would allow them to offer their very best contributions to the workplace. The first in-depth interview involved an individual who chooses not to use any assistive technology, discussing her choice and subsequent experiences in the workplace, another who has experienced but not formally reported workplace discrimination in an organisation that publicly celebrates its diversity and inclusion platform while the third in-depth interview was with an individual who works in the deafness/education sector and included a discussion of the inclusion practices of professionals in the sector. Using the complementary strengths of quantitative and qualitative methodology, the research results were analysed separately and two set of findings were produced. The integration of quantitative and qualitative data in the mixed methods reporting was completed with an eye to providing a deeper understanding of the data from one source alone. Where previously published literature comments on similar findings, references and connections are noted. The key results of the research include those that demonstrate that the disconnected or even isolated nature of the individuals in the cohort means they have few opportunities to discuss the communication challenges faced or obtain peer support in overcoming the barriers experienced in the workplace. Further, despite the difficulties experienced communicating in the workplace, it became clear that the cohort has few opportunities to trial existing technologies. Surprisingly, a third of respondents to the study had never had contact with any of the Australian support or advocacy organisations designed to assist people with hearing impairment. In the area of workplace discrimination this study reported no relationship between the age of the complainant, their title or position in the organisation, the highest level of education attained or the level of deafness experienced and the reporting of discrimination. Respondents who had experienced and reported discrimination said that in three quarters of…

▼ Hearing loss is the most prevalent sensory defect, and although hearing aids and cochlear implants can provide sensory input, no current therapeutic options exist for restoration of normal hearing. The microRNA-183 family (miR-183, miR-96, and miR-182) is highly conserved and coordinately expressed in neurosensory cells including hair cells (HCs) and sensory neurons in the inner ear, and mutations in miR-96 cause deafness in both mice and humans. To specifically investigate the effects of miR-183 family member loss-of-function, miR-183/96 and miR-182 knockout (KO) mice were assessed. Behavioral observations and evaluation of Preyer’s reflex were used to grossly assess hair cell function. Stereocilia defects and hair cell loss in mice ranging from birth (postnatal day zero; P0) to P180 were examined by immunofluorescence microscopy (IFM) detection of MyoVIIa, scanning electron microscopy (SEM), and phase contrast microscopy (PCM) of plastic embedded sections through the organ of Corti. Spiral ganglion innervation was evaluated by IFM detection for acetylated tubulin. Targetscan predicted target genes were compared to neonatal and adult hair cell transcriptomes, genes known to cause hereditary hearing loss, and miR-183 familly confirmed target genes in the literature to identify a relevant subset of genes for further evaluation. Here we show that miR-183/96 KO caused delayed stereocilia development, gross stereocilia disorganization, hair cell loss, innervation defects and deafness. Moreover, miR-183/96 heterozygous (HET) and miR-182 KO mice showed relatively subtle stereocilia defects and age-related loss of acoustic startle response. Arhgdia, Sox2 and Tes were co-expressed with miR-183 family members and mildly upregulated in miR-183/96 KO mice, suggesting such targets might play a role in the observed phenotype. Results demonstrate that miR-183 family loss-of-function (LOF) led to stereocilia defects, hair cell loss, and contributing to hearing deficits. The challenge remains to conclusively identify miR-183 family effects on target genes and pathways that support hair cell maintenance and function to provide insight to approaches for preventing hair cell loss.

▼ Damage to mechanosensory hair cells (HCs) of the inner ear leads to permanent hearing loss. Small RNAs, namely endogenous small interfering RNAs (endo-siRNAs) and canonical microRNAs, are known to affect HC development and maintenance. microRNA biogenesis requires both Dgcr8 and Dicer1, whereas siRNA biogenesis requires only Dicer1. Conditional knockout (CKO) of Dgcr8 shows HC aberrations and mild HC loss at 2 weeks of age, whereas Dicer1 CKO exhibits less HC aberrations or loss at 2 weeks of age. Thus we hypothesize there is a greater depletion of miRNAs in the inner ear of mice with HC-specific Dgcr8 CKO compared to mice with HC-specific Dicer1 CKO. |HC-specific Dgcr8 CKO and Dicer1 CKO mice were generated using Atoh1-Cre. Total RNA was isolated from the inner ears of 2 biological replicates from Dgcr8 CKO, Dicer1 CKO, and control mice. Small RNA content was examined by Illumina small RNA sequencing. Small RNA content was compared between CKO and control inner ear samples. Further examination of normalized read values included determination of microRNAs and potential endo-siRNAs that exhibited at least 2-fold differences in abundance between CKO and control inner ears, a comparison of microRNA content to previously published studies, miRNA cluster analysis, an evaluation of microRNA/host gene co-transcription, validation of a subset of miRNAs by qRT-PCR, and visualization of change between control and CKO cochlea for a selected few microRNAs by in situ hybridization (ISH). |For Dgcr8 CKO inner ear versus control, there was 1 downregulated and no upregulated microRNAs with a ≥ 2-fold statistically significant change in expression. In contrast Dicer1 CKO inner ear showed 25 downregulated and 11 upregulated microRNAs. Notably, microRNA-96, a known HC-specific microRNA, was significantly downregulated in both CKO groups. Potential endo-siRNAs showed relatively low abundance compared to microRNAs and were unchanged in Dgcr8 CKO inner ear, whereas there were 19 downregulated and 20 upregulated potential endo-siRNAs in Dicer1 CKO inner ear. Further assessments of small RNA sequencing data largely validated the subset of microRNAs that were highly abundant within the inner ear. The fold change identified by qRT-PCR, for a subset of miRNAs, was not statistically significant. ISH revealed a depletion in HC and SE-specific miRNA in both CKO mice compared to control. |Our analyses suggest that Dgcr8 may not only affect miRNAs but may also affect other classes of RNAs, such as mRNAs, compared to Dicer1. Ambiguous quantitative and qualitative results do now allow for defining the contribution of miRNAs on the more affected HC phenotype observed in Dgcr8 CKO mice compared to Dicer1 CKO mice. Investigation of both CKO mice utilizing cell specific dissection followed by small RNA sequencing may provide further insight towards the contribution of miRNAs to the HC phenotype observed.

▼ Background: Hearing aid outcomes are highly variable and important to improve. The overall objective of this dissertation is to determine how auditory processing assessments of temporal, spatial, and binaural processing are related to hearing aid outcomes in older adults. The long-term goal is to establish the evidence base supporting auditory processing evaluation as an expanded part of rehabilitative management to help target appropriate treatment and counsel on realistic expectations with recommendations not solely based on audibility alone. Methods: In this dissertation, three studies were undertaken. First, a systematic review, then clinical research in a patient population, finally a more detailed evaluation and comparison of speech-in-noise testing. In the first study, a systematic review was conducted to answer the question: “How do auditory processing abilities affect hearing aid satisfaction among adults?” Then in the second study, 78 older adults were recruited to take part in multiple evaluations of their auditory processing abilities and their non-auditory self-reports. Multiple linear regression was used to determine the strength of the relation between the different factors and hearing aid outcomes. In the third study, speech-in-noise results from the QuickSIN, Listening in Spatialized Noise Sentence Test (LISN-S), and a spatial release from masking task using the Coordinate Response Measure (CRM) materials, were evaluated and compared in 61 older adults from the second study. For this study, Pearson’s correlations, multiple linear regressions, and point-biserial correlations were used to evaluate and compare the three speech in noise tests. Results: In study one, seven studies met the inclusion criteria for the systematic review. Of these studies, the Dichotic Digits Test, the Synthetic Sentence Identification Test, and the Performance-Perceptual Test were the only tests of auditory processing ability that were significant contributors to hearing aid satisfaction. Although these studies were not rated highly for study quality, they do suggest the potential for associations between auditory processing abilities and hearing aid satisfaction. In study two, temporal processing as measured by the Gaps-in-Noise, spatial processing as measured by the LISN-S, and self-efficacy as measured by the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA), were all statistically significant predictors of hearing aid satisfaction. However, contradictory to prior studies in the literature, binaural processing on the Dichotic Digits Test was not a significant predictor. For hearing aid benefit, only the MARS-HA and self-report of disability as measured by the Speech, Spatial, and Qualities of Hearing (SSQ) questionnaire were statistically significant predictors. In study three, Pearson’s Correlations showed that only the LISN-S and QuickSIN and the LISN-S and CRM were significantly correlated to one another. The SSQ score was not correlated with performance on any of the speech-in-noise tests.… Advisors/Committee Members: Marrone, Nicole (advisor), Musiek, Frank (committeemember), DeRuiter, Mark (committeemember), Griffin, Stephanie (committeemember), Gallun, Frederick (committeemember).

▼ Background and Aims: Adults with an early-onset hearing loss are being referred to cochlear implant clinics more frequently in recent years than was observed during the early years of cochlear implantation. Open set speech perception outcomes for adults with early onset hearing loss and late age at cochlear implant are typically below those measured for adults with an acquired hearing loss, and show wider variability. This variability in outcomes makes it difficult to provide appropriate and realistic counselling regarding potential to benefit in pre-operative sessions. To address this issue, this study investigated cochlear implant outcomes and predictive factors for adults with a significant early-onset hearing loss. Method: The study design involved a prospective, longitudinal evaluation of outcomes and predictive factors for a study group of 29 adults with a significant, early-onset hearing loss who received cochlear implants at the Royal Victorian Eye and Ear Hospital, Melbourne Australia. In addition to standard pre-operative clinical assessments, receptive language was assessed using the PPVT, speech intelligibility was rated using the NTID rating scale, and communication modes (reliance on sign or oral communication) were investigated. Temporal processing was assessed via gap detection testing, non-verbal IQ was assessed using the Raven’s Progressive Matrices test (RPM), and cortical auditory evoked potentials (CAEP) were recorded. Post-operatively, speech perception was measured at 3, 12 and 24 months after surgery. At the same assessment points, electrically evoked CAEP were recorded, and correlated with speech perception results. A study questionnaire was administered post-operatively to determine if a recipient’s satisfaction with their cochlear implant was correlated with performance. Speech perception, gap detection and questionnaire results were compared to a control group of adults with an acquired hearing loss. Results: The study cohort of 29 adults with significant early-onset hearing loss gained significant benefit from their cochlear implant, as measured by increased speech perception results post-operatively. Results, however, were significantly lower than those obtained from 576 adults with an acquired hearing loss from the Royal Victorian Eye and Ear Hospital. Receptive language was not correlated with post-operative speech perception, but was correlated with speech intelligibility; participants with greater speech intelligibility achieved better post-operative speech perception results. Those participants who used purely oral language achieved better speech perception and had better speech intelligibility than those who used some signing for communication. Gap detection was correlated with performance, with those participants with lower gap detection scores achieving better speech perception results. Both cortical evoked responses and non-verbal IQ were not correlated with outcomes. Adults with an early-onset hearing loss scored significantly lower than adults with an…

▼ Sclerosteosis is a rare genetic bone dysplasia disorder characterised by generalised craniotubular bone modelling. Alongside many clinical appearances marked in sclerosteosis, the auditory system is considerably compromised on several levels during the disease progression. Extensive otolaryngological research on the history of sclerosteosis, the clinical presentation of sclerosteosis, radiographic studies and the gene causing the condition had been documented. No studies had been found describing the audiological profiles, auditory functioning and abnormalities for subjects with sclerosteosis. Thus the object of this study aimed to describe the auditory profile of subjects with sclerosteosis. A cross-sectional descriptive research design and quantitative research approach was followed to investigate the auditory characteristics of subjects with sclerosteosis. Subjects were selected from a database of patients with confirmed diagnoses of sclerosteosis. Ten subjects responded and provided written informed consent. Test procedures included otoscopy, tympanometry, acoustic reflexes, diagnostic pure-tone airand bone-conduction audiometry, speech audiometry, distortion product otoacoustic emissions (DPOAE), auditory brainstem responses (ABR) and computed tomographic (CT) scans. The subjects were assessed with a comprehensive audiological test-battery within a single test session lasting approximately two hours. A CT scan was conducted on a separate occasion shortly after the audiological data were obtained. Normal type A tympanograms were obtained in 50% (n=10/20) of ears. All subjects presented with mixed hearing losses varying from moderate (5%; n=1), severe (55%; n=11) and profound (40%; n=8) degrees across ears. Hearing loss configurations ranged from rising (15%), sloping (35%) and air-conduction thresholds peaking at 2000 Hz (50%). Air bone gaps (ABG) were larger in older subjects, although not statistically significant (p>.05). The CT scans indicated anatomical abnormalities of the external auditory canal, tympanic membrane, middle ear space, ossicles, oval window, round window and the internal auditory canal. The progressive abnormal bone formation in sclerosteosis involved the middle ear, the round and oval windows of the cochlea and internal auditory canal. The progressive abnormal bony overgrowth, which is the hallmark of sclerosteosis, led to functional impairment at various levels in the auditory system. The current findings provided a comprehensive auditory profile for sclerosteosis. Results might be utilised alongside future research findings to direct criteria and audiological indications for surgical and audiological intervention.

▼ RESUMO: A surdez súbita (SS) caracteriza-se por uma perda abrupta de audição, mais frequentemente unilateral e associada a sensação de preenchimento aural, acufenos e vertigem. Afecta 5-20/100.000pessoas/ano (sobretudo adultos em fase activa na década de 40), com grande impacto na qualidade de vida. Possíveis causas incluem doenças infecciosas, circulatórias, traumáticas, imunológicas, neoplásicas, neurológicas, tóxicas e cocleares. No entanto, a causa da SS permanece desconhecida na maioria dos casos (80%), o que origina tratamentos controversos e frequentemente ineficientes. Os tratamentos disponíveis variam desde corticosteróides a antivirais, vasodilatadores, anti-agregantes, anticoagulantes, vitaminas e oxigénio hiperbárico (OHB). Atendendo a falta de informação relativa à etiologia e fisiopatologia da SS, pretendemos avaliar a evolução clínica dos doentes com SS tratados com OHB no Centro de Medicina Subaquática e Hiperbárica (CMSH) de Lisboa entre 2000 e 2005, durante um período mínimo de 5 anos, na tentativa de identificar eventuais factores de risco ou noxas clínicas com a SS. O estudo retrospectivo proposto baseia-se na revisão de processos clínicos do CMSH e na aplicação telefónica de questionários médicos de “follow-up” confidenciais – tanto a doentes (grupo de estudo), como aos respectivos esposos/companheiros/membros próximos da família (grupo de controlo) –, com particular ênfase nos antecedentes médicos e história clínica actual. Um estudo preliminar de 20 pessoas (10 doentes e 10 controlos) foi efectuado para antecipar dificuldades e estimar as necessidades logísticas. As dificuldades identificadas foram: 1) selecção dos doentes com números de telefone válidos e processos clínicos completos (com audiograma inicial e final); 2) contacto telefónico com os participantes de ambos os grupos (de estudo e controlo); 3) recursos humanos requeridos. Dado que a SS não é uma doença em si, mas um sintoma de uma doença subjacente, acreditamos que este estudo epidemiológico seja importante e útil, capaz de gerar novas luzes sobre a fisiopatologia e mecanismos desta entidade clínica. – – – – -ABSTRACT:Sudden sensorineural hearing loss (SSHL) is characterized by abrupt, mostly unilateral loss of hearing, frequently associated to aural fullness, tinnitus and vertigo. It affects 5-20/100.000 people/year (particularly working adults in the 40ths), with huge impact on quality of life. Possible causes include infectious, circulatory, traumatic, immunologic, metabolic, neoplastic, neurologic, toxic and unidentified cochlear diseases. Nevertheless, SSHL’s etiology remains unknown in most cases (80%), giving rise to controversial (and frequently ineffective) treatments. Available therapies range from corticosteroids to antivirals, vasodilators, antiaggregants, anticoagulants, vitamins and hyperbaric oxygen (HBO). Given the lack of data concerning SSHL’s etiology and physiopathology, we intend to evaluate clinical evolution of such patients treated with HBO in the Underwater and Hyperbaric Medical Center (UHMC) at Lisbon…

Can listening to information at a low volume improve hearing? To test this hypothesis this experiment had undergraduate students listen to a podcast at a low volume. In addition, this study also explored expectation or priming someone to anticipate a particular outcome. The central questions of this study asked how both listening to a podcast at a low volume and expectation influenced hearing outcomes, reaction times, the comprehension of auditory information and perceived mindfulness. A secondary line of inquiry examined whether one’s perceived mindfulness is correlated with reaction times. To this end, 111 Harvard undergraduate students with no history of hearing impairment were recruited into a 2 x 2 factorial designed study, where podcast volume and expectation were the factors at play. All participants completed a Langer Mindfulness Scale and a hearing test before being placed into one of four conditions: condition 1, participants listened to a podcast at a regular volume and were told they could expect their hearing to improve, condition 2, participants listened to a podcast at a regular volume, condition 3, participants listened to a podcast at a low volume and were told that they could expect their hearing to improve, and condition 4, participants listened to a podcast at a low volume. Participants then completed a second Langer Mindfulness Scale and hearing test, as well as a visual reaction time test, an auditory reaction time test and a quiz designed to test participants’ comprehension of the podcast material. This study found that found that that participants that listened to podcasts at a low volume would experience improvements in their posttest hearing test scores. Additionally, being within an expectation group was significantly associated with better scores on hearing tests. It should be noted that this study presupposed that listening to podcasts at a lower volume level will allow participants to mindfully notice change. Due to the fact that other mindfulness interventions have produced positive changes in auditory processing (Langer, 2009) this study’s results may give further credence to the notion that engaging in mindfulness can positively impact sensory processing. In light of these results it may be prudent to explore whether listening to information at a low volume can improve the hearing of those who live with mild to moderate hearing impairment. Conversely, based on the analysis of this thesis the podcast volume and expectation were not significantly correlated with reaction times or perceived mindfulness. Similarly, perceived mindfulness was not significantly correlated with reaction times. Lastly, the comprehension assessment used to evaluate the comprehension of podcast material proved to be too easy. As a result, a ceiling effect was observed and thus whether listening to podcasts at a low volume impacts comprehension remains unknown.

▼ Sound levels in the live music industry have been demonstrated to reach levels capable of causing harm to the auditory system. The body of work presented here aimed to explore ways in which hearing injury can be prevented in the Australian music industry. To do so, multiple stakeholders were engaged, including venue owners, live-music sound engineers, audiologists and manufacturers of hearing protectors for musicians. Four discrete, mixed-methodology studies were conducted to address the topic. Study 1 aimed to investigate the clinical provision of musicians’ hearing protectors (MHPs) by audiologists and manufacturers of MHPs in Australia. Method. Audiologists and manufacturers were asked to complete one of two surveys, investigating the delivery of clinical care for musicians, and recommended processes relating to the manufacture of earplugs. Results. Inconsistencies in the clinical procedures were noted in both the practice of audiological care for musicians, and the recommendations made by manufacturers of MHPs. Study 2 aimed to investigate whether the use of, and satisfaction with, MHPs is influenced by the specific treatment delivered to musicians by audiologists. Method. Musicians rated their satisfaction with the services as delivered across the four treatment conditions. Results. No statistically significant differences across conditions were observed, however, certain aspects of care were perceived positively by musicians, such as the provision of a hearing test. Study 3 aimed to assess the hearing of live music sound engineers and their risk of hearing injury. Method. Participants completed a questionnaire on their hearing health as well as a hearing assessment. Results. Ninety-six percent of sound engineers reported having experienced at least one symptom of hearing injury during or after a work shift in music. Use of hearing protection was low, however, individuals who frequently wore hearing protection had significantly better hearing, particularly in the extended high frequencies. Study 4 aimed to investigate if the use of sound level management software can assist in reducing exposure levels in indoor live music venues. Method. Use of a commercial sound level management system in six indoor live-music venues of Melbourne was trialled. Results. Overall, there was no reduction in mean sound level (LAeq,T), however the number of nights on which extreme volume levels were recorded was reduced. Subjective questionnaires indicated that one-fifth of patrons would prefer lower sound levels than experienced. Overall, the results indicate there is a significant risk of hearing injury to individuals working within and attending live music venues in Australia. Findings indicated that there is a need for greater hearing awareness across all stakeholders. Audiologists would benefit from the development of best-practice guidelines for the care of musicians’ ears, while more broadly, the inclusion of EHF hearing thresholds would benefit in early detection and…

▼ Hearing impairment (HI) is a growing health issue in today’s ageing society. Research has suggested that individuals with HI may experience increased levels of anxiety. Previous research has mainly focused on anxiety as a trait; recent research, however, has looked at state anxiety in the hearing impaired population. Cognitive anxiety is a state anxiety that occurs when people encounter a situation which does not lie within their construct system. As a result, they may experience anxiety as they are unable, or only partially able, to interpret the event meaningfully and are therefore unable to judge the implications of this event. The following study aimed to use the Cognitive Anxiety Scale to investigate relationships between cognitive anxiety and client variables in hearing impaired individuals, adding to the small amount of research currently available in this area. The following research questions were investigated: (1) Is there a relationship between cognitive anxiety level and (a) age, (b) gender, (c) audiometric variables, and (d) quality of life? (2) Is there a significant difference between the level of cognitive anxiety for the participants who purchased and kept hearing aids and those who did not? Twenty-five hearing impaired individuals who were consulting an audiologist for the first time participated in this study, with the cognitive anxiety interview conducted prior to the audiological assessment. The results indicated that cognitive anxiety was significantly related to an ability to understand speech in noise and quality of life, and that hearing aid adopters exhibited greater levels of cognitive anxiety than non-adopters. These results confirm that cognitive anxiety is indeed experienced by adults with HI, and suggest that it may be a factor which motivates people to adopt hearing aids. Further research is needed to confirm and further investigate the relationships with client variables. By listening for signs of cognitive anxiety, an audiologist may be able to gauge if a client is ready for rehabilitation, and encourage the process by exploring the effects of HI on communication situations, employing speech in noise testing, and including the significant other in the process.

▼ In Orchestra musicians hearing plays a very important role, and slight alterations in their hearing will have a significant impact on their performance ability as musicians. Although the effect of orchestra music on hearing is documented, existing researches have several drawbacks, and in most studies measurement of musical sound exposure is not linked to audiological test results. Some variables that may have a significant influence on resulting hearing loss are not taken into consideration. The literature review shows a confusing picture, and some studies identify high-frequency notches suggestive of noise induced threshold shift while others suggest musicians’ hearing levels are not significantly different from a non-exposed population. There are strict legal requirements for the daily noise exposure a worker can receive in workplace but nothing to regulate non-occupational noise and music exposure. This research work sets out to study the effects of playing in an orchestra on various age groups of musicians, to identify important variables that may potentially contribute to resulting hearing loss, and how playing in an orchestra or a band affects children in particular. In this study 37 out of 61 adult musicians (61%), 19 out of 85 youth musicians (22%) and six out of 37 children musicians (16%) were found to have a hearing loss. The sound exposure measurements confirm that there is an increased risk for hearing loss of all ages and the majority of musicians are also exposed to high impulse noise with the peak level of above 140dB. There is a broad individual difference in sensitivity and vulnerability. It is often difficult to estimate total sound exposure for every musician. Individual susceptibility seems to depend on known and unknown factors and interaction between intrinsic and extrinsic factors. Personal ear protection devices are seldom used among the musicians. Hence this study stresses the importance of an individualised hearing conservation programme that includes identifying all potential variables/factors that may increase the risk. This thesis addresses the development of hearing loss in orchestra musicians, audio logical findings among players of different musical instruments, and methods of effective hearing conservation programmes for preventing hearing loss in musicians.

▼ Despite the preventability of noise-induced hearing loss (NIHL) a high prevalence is still reported in South African mines. The study aimed to describe the hearing of gold miners pertaining to the prevalence and degree of NIHL and effectiveness of current RSA impairment criteria to identify NIHL. The audiological data, collected between 2001 and 2008, of 57 714 mine workers were investigated in this retrospective cohort study. Data was accessed through the mine’s electronic database and exported to Microsoft Excel 2007 worksheets. Participants were categorised in terms of noise exposure (level and working years), age, race and gender. Noise exposure levels were described in terms of a specific occupation and categorized into four groups based on dosimeter data received from the mine’s noise hygienist, namely: 1) Below surface (underground) noise exposure, ≥85 dB A, classified according to the South African regulations on the daily permissible dose of noise exposure8, named Noise Group 1; 2) Surface noise exposure, ≥85 dB A, named Noise Group 2; 3) No known occupational noise exposure, named control group; and 4) Uncertain levels of noise exposure, e.g. students and trainees, named Noise Group 4. The control group was matched with participants of noise group 1 and 2 based on gender, race and age at the most recent audiogram test. Descriptive and inferential statistics were employed. Measures of central tendency and variability were used with analysis of covariance (ANCOVA) and pairwise comparisons according to Fisher’s Least Squares Differences Approach (F test). Results indicated that noise exposed groups had significantly higher prevalence of high and low frequency hearing loss than the control group. High-frequency hearing loss was also present in the control group. The greatest differences in prevalence of hearing loss were observed at 3, 4 kHz and age group 36 to 45 years. Thresholds at 8 kHz were worse than expected and decline slowed down with age. High-frequency thresholds showed a non-linear growth pattern with age with a greater decline at 2 kHz with age in the noise-exposed population compared to the control group. Hearing deteriorated more across age groups with more noise-exposed years, and this deterioration was most visible after 10 to 15 working years and at 3 kHz. Females had better hearing than males across the frequency spectrum. Black males had significantly better high-frequency hearing than white males but significantly worse low-frequency hearing than white male counterparts. PLH values showed poor correlation (through statistical analyses) with other well-accepted hearing impairment criteria. To date this was the largest study conducted on the hearing of gold miners and the sample included a very large number of black males exposed to occupational noise (N=17 933). Values supplied in distribution table format are therefore unique and contribute greatly to the knowledge base. Advisors/Committee Members: Prof D C D Swanepoel (advisor).

Os estados do Nordeste brasileiro concentram elevadas taxas de pessoas com deficiências, mas pouco se estudou a respeito de suas causas. O objetivo desse estudo foi determinar a prevalência da deficiência auditiva e estimar a contribuição dos fatores genéticos na sua etiologia nas populações de dois municípios do Nordeste brasileiro. Após indicação pelos agentes comunitários de saúde para avaliação clínico-genética, foram avaliados 182 indivíduos com perda auditiva manifestada antes dos 60 anos dos municípios de Gado Bravo (76 pacientes) e Queimadas (106 pacientes), com população de 8.376 e 41.049 habitantes, respectivamente. Em Queimadas, 13 pacientes eram homozigotos com a mutação c.35delG no gene GJB2 (13/106, 12,2%; 6/81, 7,4% das famílias). Já em Gado Bravo, somente um paciente era homozigoto com esta mutação (1/76, 1,3%; 1/55, 1,8% das famílias). A mutação m.A1555G no gene mitocondrial MTRNR1 e a mutação c.167delT no gene GJB2 não foram detectadas em ambos os municípios. Quanto às deleções do GJB6, apenas a del(GJB6-D13S1854) foi encontrada em quatro casos em Gado Bravo (4/76, 5,3%; 2/55, 3,6% das famílias). Após o sequenciamento completo do gene GJB2, foi detectada a mutação p.W24X (c.G71A) em heterozigose em três casos isolados do município de Gado Bravo (3/76, 3,9%). Em resumo, mutações patogênicas no lócus DNFB1 foram encontradas em 16% (34/212) dos alelos testados no município de Queimadas e em 9,9% (15/152) dos alelos testados no município de Gado Bravo. No total da casuística, ocorreram 11 pacientes com uma única mutação recessiva detectada (monoalélica) no lócus DFNB1. As amostras desses 11 pacientes foram submetidas à análise de MLPA na tentativa de identificar uma segunda mutação, do tipo variação do número de cópias, mas nenhuma mutação foi encontrada. O gene SLC26A4 foi sequenciado em amostras de famílias com padrão de herança autossômico recessivo sem mutação detectada no lócus DFNB1, que apresentaram ligação compatível por meio de microssatélites na região próxima a esse gene. Não foi detectada nenhuma mutação patogênica na região de código desse gene. Após o estudo de ligação por meio de array de SNPs e microssatélites em uma família com quatro afetados pela síndrome de Usher do município de Gado Bravo, o gene CLRN1 apareceu como provável candidato e as amostras desses pacientes foram selecionadas para sequenciamento. Foi detectada a mutação p.Y63X em homozigose nos quatro pacientes. As amostras dos outros pacientes com essa síndrome também foram sequenciadas. Essa mutação foi encontrada em homozigose em 21 dos 23 casos de síndrome de Usher em Gado Bravo. A porcentagem de casos de surdez com provável etiologia genética em Gado Bravo e Queimadas foi estimada em 55% e 45%, respectivamente

▼ The ability to adequately perceive and utilize the prosody of spoken language is important for successful communication. Children with hearing loss who use cochlear implants have demonstrated deficits in perception of stress and intonation in spoken language, but not rhythm in music, compared to children who use hearing aids or children who have normal hearing. These deficits have been attributed in part to limitations of cochlear implant technology. Wearing a hearing aid in addition to the cochlear implant can reduce some of these deficits. In this study, perception of stress, intonation, and speech rhythm was compared among 8-16 year old children with hearing loss who used cochlear implants, children with hearing loss who used bimodal technology - one cochlear implant and one hearing aid in the contralateral ear, and children with normal hearing. The results of this study indicated that most children were sensitive to stress, intonation, and rhythm of speech. Children with hearing loss were comparable to children with normal hearing in their sensitivity to stress and rhythm, and intonation present in unfiltered, connected speech, but were deficient in their perception of intonation present in low-pass filtered speech. Children with hearing loss were comparable to children with normal hearing when identifying the language of an utterance based on phonemic and prosodic cues, but were deficient when minimal phonemic cues were present. Children who used bilateral cochlear implants performed similarly to children who used bimodal technology, indicating that sensitivity to prosodic features was possible with either of the hearing technologies. Audiological factors such as early amplification, longer duration of auditory exposure, and adequate low-frequency access had a positive impact on perception of prosody in speech. The finding that children with hearing loss were comparable to children with normal hearing in their perception of stress and intonation is in contrast to previous findings, and might be attributed to differences in task design as well as in audiological and intervention characteristics of the children in this study compared to previous studies.

▼ Background: Tuberculosis therapy is characterized by many side effects including hearing loss. It has been documented that the use of aminoglycosides for TB treatment is the cause of the associated hearing impairment. The consequential effect of hearing impairment on the patient is high. This has its long-term socio-economic effect (social isolation and stigmatization) on patients, families and public health in general. Hearing loss can compromise treatment compliance and also affect the quality of life of patients during and after treatment. Aim: The aim of the study was to determine and establish the prevalence of hearing loss among patients receiving treatment for TB. Method: A quasi-experimental, post-test only with non-equivalent control group design involving 60 consenting patients receiving treatment for TB at the chest clinic of the Tema General Hospital between February and May 2018 and a control group of 60 age and gender-matched uninfected volunteers constituted this study. Data on demographics and case history were collected using a structured questionnaire. The hearing status of participants was assessed using conventional pure tone audiometry and transient evoked otoacoustic emission tests. Data were analyzed using the SPSS statistical software package. Results: A hearing loss prevalence of 20% was found among patients receiving treatment for TB. Out of the 60 patients on TB medications assessed, 12 presented with hearing loss that ranged from mild to severe. Patients who presented with the poor thresholds were all referred in the OAE. Hearing thresholds of patients receiving anti-TB medications were significantly elevated (p<0.05) in comparison to the thresholds of the control group. A statistically significant (p<0.05) difference was observed between the hearing thresholds of patients receiving treatment and the uninfected volunteers especially at the high frequencies. A similar significant (p< 0.05) association was also found between exposure to TB medications and poor hearing thresholds. Conclusion: Patients receiving treatment for TB usually demonstrate significantly elevated hearing thresholds which tend to be more pronounced at the high frequencies. Audiological management of these patients should, therefore, be an essential part of their therapeutic treatment plan. This will help improve their quality of life during and after treatment.

▼ The purpose of this dissertation work was to examine the impact of auditory deprivation in the form of age-related hearing loss (ARHL) and auditory stimulation in the form of hearing aid use, on the neural registration and abilities to use sound for higher level cognitive tasks, in older adults (aged 55-75). Three groups were examined: 1) NH: older adults with clinically normal hearing, 2) u-HL: peers with bilateral mild to moderate/moderately- severe sensory-neural hearing loss who have never worn hearing aids and 3) t-HL: peers with a similar amount of hearing loss, but who have been treated through binaural amplification (hearing aids). Participants completed two sessions: 1) Behavioral tests: Audiometry, cognitive screening, quality of life questionnaires, nonverbal IQ test, speech recognition in quiet and noise, and tests of verbal working memory function (both auditory and visual); 2) Electrophysiology: Evoked potentials (P1-N1-P2) recorded in response to a speech syllable presented at two different sound levels (equal sound pressure level (SPL) and equal sensation level (SL)). All three groups performed similarly on tests of speech perception in noise, working memory and nonverbal IQ, but differed on self-report measures of hearing handicap. Both hearing loss groups indicated greater reported greater hearing handicap (HHIE) than NH groups. Additionally, individuals with untreated hearing loss showed a positive relationship between working memory performance and speech understanding in noise. Neural measures indicated significant morphological differences (latency and amplitude) between groups, but only when the stimuli were presented at equal SPL. Once audibility was accounted for (equal SL levels) these differences were not present, suggesting group differences were due to audibility, and not central changes secondary to auditory deprivation. Results highlight the importance of the audibility of sound, and suggest that early sound processing and later use of sound for processes involved in communication is not permanently affected by mild to moderate/moderately-severe ARHL.

▼ Despite the preventability of noise-induced hearing loss (NIHL) a high prevalence is still reported in South African mines. The study aimed to describe the hearing of gold miners pertaining to the prevalence and degree of NIHL and effectiveness of current RSA impairment criteria to identify NIHL. The audiological data, collected between 2001 and 2008, of 57 714 mine workers were investigated in this retrospective cohort study. Data was accessed through the mine’s electronic database and exported to Microsoft Excel 2007 worksheets. Participants were categorised in terms of noise exposure (level and working years), age, race and gender. Noise exposure levels were described in terms of a specific occupation and categorized into four groups based on dosimeter data received from the mine’s noise hygienist, namely: 1) Below surface (underground) noise exposure, ≥85 dB A, classified according to the South African regulations on the daily permissible dose of noise exposure8, named Noise Group 1; 2) Surface noise exposure, ≥85 dB A, named Noise Group 2; 3) No known occupational noise exposure, named control group; and 4) Uncertain levels of noise exposure, e.g. students and trainees, named Noise Group 4. The control group was matched with participants of noise group 1 and 2 based on gender, race and age at the most recent audiogram test. Descriptive and inferential statistics were employed. Measures of central tendency and variability were used with analysis of covariance (ANCOVA) and pairwise comparisons according to Fisher’s Least Squares Differences Approach (F test). Results indicated that noise exposed groups had significantly higher prevalence of high and low frequency hearing loss than the control group. High-frequency hearing loss was also present in the control group. The greatest differences in prevalence of hearing loss were observed at 3, 4 kHz and age group 36 to 45 years. Thresholds at 8 kHz were worse than expected and decline slowed down with age. High-frequency thresholds showed a non-linear growth pattern with age with a greater decline at 2 kHz with age in the noise-exposed population compared to the control group. Hearing deteriorated more across age groups with more noise-exposed years, and this deterioration was most visible after 10 to 15 working years and at 3 kHz. Females had better hearing than males across the frequency spectrum. Black males had significantly better high-frequency hearing than white males but significantly worse low-frequency hearing than white male counterparts. PLH values showed poor correlation (through statistical analyses) with other well-accepted hearing impairment criteria. To date this was the largest study conducted on the hearing of gold miners and the sample included a very large number of black males exposed to occupational noise (N=17 933). Values supplied in distribution table format are therefore unique and contribute greatly to the knowledge base. Advisors/Committee Members: Swanepoel, De Wet (advisor).
