▼ Noise in the workplace is a common occurrence. These sounds can have various characteristics that can affect each individual. Many people around the world subject themselves to loud noises at recreational activities including concerts, monster truck rallies, and sporting events. Some individuals also work these events as security employees, referees, and concession workers. Depending on the arena and the sport, games may take place one to four days a week at a particular venue. The National Institute for Occupational Safety and Health (NIOSH) identifies exposure to noise as one of the most common hazards associated with workplaces. According to the National USA Hockey League, there are over 20,000 registered officials (referee/linesman) regulating hockey in the United States. The identified hockey official population could be at risk of developing noise induced hearing loss (NIHL) because of the noise exposure at hockey games. For this study, personal noise dosimeters and a sound level meter were used to record noise exposures during hockey games for the 2014 season to ascertain if hockey referees were at increased risk of NIHL. A total of 30 personal noise samples and 20 area noise samples were collected. The study was completed in December 2014. The noise dosimetry results were compared to the Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL), OSHA Action Level (AL), and American Conference for Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV). Noise dose was calculated for each official per game to determine if noise controls were warranted at this specific venue. No referees or linesmen were overexposed to noise when compared to the OSHA PEL. However, twenty-five referees and linesmen (89%) were overexposed to noise according to the ACGIH recommendations (85 dBA, 3 dB exchange rate), and two officials (7%) were exposed above the OSHA Action Level (85 dBA, 5 dB exchange rate). An average equivalent sound-pressure level (Leq) range of 79 dBA to 90 dBA was measured using a sound level meter at four locations in the arena over five games. In addition to area and personal monitoring, the number of whistle blows by the officials was counted during the first period of four games, and the average number of whistle blows per game for referees and linesmen was 60. According to previous researchers, whistle blows are one of the loudest and closest noise sources to referees. Some whistles reach sound levels as high as 116 dBA. Based on the results, it is recommended that this venue take preventative action in reducing noise exposure for hockey referees. Future research should continue sampling at sports arenas and focus on implementing control measures in hockey arenas.

▼ The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof – like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel. After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction – at least not when government regulations of acceptable noise levels are applied. To reach these acceptable noise levels at large traffic roads, noise barriers must be constructed at a larger scale or else the roads must be built below ground level. The Noise tunnel has therefore been investigated as an alternative noise solution. With the reduced noise levels resulting from the Noise tunnel, it will be possible to exploit new land for construction –something which would contribute to the funding of the Noise tunnel. In order to investigate the Noise tunnel in a more concrete way, a part of Nynäsvägen has been studied. Nynäsvägen is a large road situated south of Stockholm, and some parts of the road, as well as its surroundings, suffer from severe noise problems. Moreover, there is unexploited land available near Nynäsvägen, and this could be used for constructions. The result of the investigations shows that the Noise tunnel is approximately 10 times more expensive than a noise barrier, but 10 times cheaper than decking over the road. Furthermore, it has been found that it is possible to construct the Noise tunnel with today’s production methods. This conclusion is supported by both primary research and observations from similar projects conducted abroad. It has been found that the Noise Tunnel represent an alternative solution at large traffic roads in urban environments where noise problems are of concern. This thesis concludes that although there are no technical problems preventing the Noise tunnel from becoming reality, the incentives to implement it are likely to represent a greater barrier.

▼ With the development of the industry and the society, noise pollution becomes increasingly severe, especially in large cities. Generally, there are three major noise sources, namely industrial noise, traffic noise and community noise. In response, several measurements have been developed to achieve effective noise control. Examples of noise control methods are reduction of noise at source and abatement of noise during the transmission. Since noise sources are more difficult to control, and sometimes already fixed, noise control during sound transmission is more broadly applied. Traditional passive noise control techniques include Helmholtz resonators and noise absorption materials like felt, glass mineral. The sound absorption materials (SAM) are found to be efficient in attenuating noise in high frequency domain, but their performance at low frequencies is quite poor. On the other hand, the Helmholtz resonator works perfect at any target frequency but suffers from its narrow absorption bandwidth, so that it’s only effective within a limited frequency band. As an innovative solution to passive noise control problem, micro-perforated panel absorber (MPPA) has attracted great interest in recent years. It turns out to be a competitive alternative to sound absorption materials and Helmholtz resonator. The parallel and series arrangement of MPPAs backed with cavities of different depths allows them to obtain decent noise absorption performance over a relatively broad frequency range. However, the performance of MPPA is restricted by its volume, as large volume is demanded for decent low-frequency absorption, which is also the case for noise absorption materials. In this thesis, a potential way to improve the low-frequency performance of the MPPA without occupying extra volume is proposed and implemented to tests. The focus is the adjustment of speed of sound and it is beneficial in different applications such as the following. In low frequency noise control, the size of the absorber in at least one dimension is often related to the wavelength and it is often too long. With a reduced speed of sound one can reduce this size while keeping the overall volume constant. Along this line of thinking, the effect of cavity configuration on its acoustic properties is investigated by two steps. Firstly, the property of a waveguide consisting of several identical elements is studied. The number of element is chosen to magnify the effect of the configuration. It turns out the irregularity of the duct shape can slow down the speed of sound of the plane wave by increasing the acoustic mass. Secondly, the absorption performance of an MPPA backed with an irregular cavity is evaluated. The shape of the cavity is the same as the element in the first step. In advance, the parallel arrangement of two MPPAs backed with irregular cavities is investigated, in order to look into the effect of cavity shape on inter-resonator interaction. The final results indicate that cavity design is an effective method to enhance the noise absorption…

Triukšmo poveikis aplinkai buvo tirtas šaudant iš priešlėktuvinių pabūklų L70 ir RBS-70 netoli Juodkrantės esančioje teritorijoje. Nustatyta, kad priešlėktuvinės artilerijos pabūklo L70 keliamas triukšmas neviršija leistinas triukšmo normas gyvenamųjų ir poilsio namų teritorijose. Įvertinus turimus mokslinės literatūros šaltinius, triukšmo matavimo rezultatus bei vizualinių stebėjimų duomenis, nustatyta, kad šių pabūklų keliamas triukšmas nepaveiks paukščių migracijas. Taip pat RBS-70 ir L70 pabūklų keliamas triukšmas negali įtakoti paukščių būklės žiemavietėse ties Lietuvos Kuršių nerijos pajūrio krantais dėl per didelio atstumo ir garso išsisklaidymo. Remiantis literatūra, pratybų metu keliamas triukšmas galėtų turėti neigiamos įtakos netoli nuo šaudymo vietos perintiems paukščiams, bei Juodkrantės šiaurinėje pliažo teritorijoje esantiems poilsiautojams, todėl nerekomenduojama vykdyti pratybų paukščių perėjimo ir vasaros poilsio sezono metu. Nustatyta, kad iš priešlėktuvinio pabūklo RBS-70 keliamas mažesnis triukšmas nei iš L70, todėl šio pabūklo triukšmo poveikis aplinkos komponentams bus mažesnis.

The effect of noice to environment caused by shooting of antiaircraft cannons L70 and RBS-70 was investigated in an area located near village of Juodkrante. This study revealed that the level of noise which was caused by L70 is esunder limits of residential and recreation zones. According to results of research, scientific publications and data of visual observations, we found out that noise made of antiaircraft guns could not affect the migration of avifauna. Also it was established that noise made of L70 and RBS-70 could not have any negative influence to avifauna in places of hibernation which are located beside the coasts of Kursiu nerija. However, the boom produced during the military practice could have some negative effects to sitting birds near the training ground. Furthemore, it could cause some problems to holidaymakers situated on the north side of the beach of Juodkrante. Thus it is not recommended to do the military practice during the summer-season and breeding-time of aviflauna. Additionally, we ascertained that the level of noise caused by antiaircraft gun RBS-70 is lower in comparison to L70. Thus the negative influence of RBS-70 to environmental components could be lower than L70.

▼ A six mooring acoustic tomography array was jointly deployed by Scripps Institution of Oceanography and Woods Hole Oceanographic Institution in 1988, and a year long time series of ambient noise in the 200-300 Hz was collected by those moorings. Large scale meteorological environmental information, particularly wind, was provided during that same year by the British Meteorological Office. Time series of ice type and ice concentration were provided by Special Sensor Microwave Imager and Advanced Very High Resolution Radiometer satellite. Using those data sets, we were able to look at the characteristics of the ambient noise and to correlate the noise against significant environmental variables such as wind , ice concentration, ice edge position, etc. The largest noise levels are generally seen during the winter months and are associated with periods of moderate to strong wind speed. The lowest noise levels are confined to summer; however, there is also an extremely quiet period in mid-winter, coincident with heavy ice cover. During the ice-free periods, the ambient noise is higher than the Wenz ambient noise for open water. The regressions between the noise and wind speed show that the noise is wind dependent, with slightly lower slopes than the Wenz curve. Under the heavy pack ice cover conditions, noise levels are much lower than during the ice-free periods, even lower in fact than Wenz noise for open water when the wind speeds pass 11 m/s. The ambient noise is almost wind independent during this period. The overall noise levels are highest during the ice edge advance/ retreat period; the noise is also wind dependent , with the regression slopes higher than that for ice-free period, but still lower than that of the Wenz curves. . Noise and wind fields correlate well in fall and during the ice edge advance/ retreat periods, but are less correlated under the heavy ice cover and during low wind speed periods. The spatial cross correlations of the noise fields show quite high levels, up to 0.9 in fall and during the ice edge advance/ retreat period, but there is less correlation during other periods. The MIZ noise levels are dependent on the distance between the receiver and the ice edge and also the ice concentration. The noise peaks at the ice edge and diminishes faster going under the ice than into the open water. The measured noise levels near the ice edges are about 4 to 7 dB higher than open water, and about 7 to 10 dB higher than levels far into the ice field. In the MIZ, on-ice-wind results in higher noise than off-ice-wind. Ambient noise increases as on-ice-wind increases, but increases much slower or even decreases as off-ice-wind increases.

▼ Development of new research tools is needed to better understand the potential effects of a noisier ocean on individual and populations of marine mammals. Current behavioral response studies utilize ship-mounted sound sources to induce short-term noise-related behavioral responses in tagged animals. Combining the tag with the sound source into an animal-mounted active acoustic and motion sensing tag could potentially allow for long-term, more controlled and cost-effective behavioral response studies. Field tests were conducted on juvenile northern elephant seals, Mirounga angustirostris, using both natural and anthropogenic stimuli, to evaluate the potential of such a prototype tag. Results showed that such an instrument does elicit behavioral responses in tagged individuals. Responses during the ascending phase of a dive consisted of a dive inversion, with the animal diving as deep as or deeper than its original dive depth (seven of nine exposures). Change in dive depth following exposure was significantly larger than change in depth for non-exposure inversions. A single exposure at the bottom phase of a deep dive followed the same pattern. Dive inversions were observed following white noise, sperm whale clicks, killer whale whistles, and sonar exposures, but not following common dolphin whistles. Responses to exposures received during the descending phase of a dive resulted in an increased descent rate in nine of ten exposures. All eight exposures during shallow dives, where the animals were likely limited by bathymetry from diving any deeper, were characterize by increased flow noise following exposure, an indicator of increased swim speed. Results showing differential responses to specific exposure stimuli were inconclusive. Tag improvements and additional field efforts are needed to validate the tag’s use in behavioral response studies to specific acoustic stimuli. There is potential to use this technology to study physiological effects of extended deep dives on marine mammals as well as frequency dependent hearing because of its ability to induce prolonged, unplanned dives in response to man-made sounds.

▼ The reduction of fan noise contributions to the engine noise spectrum is an important area in overall engine design as noise restrictions on commercial aircraft are increasingly stringent from one year to the next. The ability to predict this noise furthers understanding of the noise-producing mechanisms of turbofan engines and may serve to develop noise control and suppression techniques. The current state-of-the-art noise prediction model is a two-dimensional linear cascade model with strip theory. A fully three-dimensional annular cascade model is presented, and comparisons are made against a linear cascade for various sound-generating interactions in the fan section of a high-bypass turbofan engine. First, the applicability of a linear cascade model with strip theory in determining the radiated noise from a realistic rotor wake with a stator cascade is presented. Results indicate that the two-dimensional model under-predicts the tonal noise of the annular cascade model. Second, the importance of flow turning, which is accounted for in the annular cascade model but not in the linear cascade model, is investigated. It is shown that the mean flow turning strongly affects the resulting intensities of the propagating acoustic modes, therefore indicating that a two-dimensional theory is insufficient. Third, as broadband noise has become an important component of the noise spectrum of turbofan engines, a broadband noise prediction model is presented for realistic engine cascade geometries. Comparisons between the linear and annular cascade predictions with experiments also indicate that a three-dimensional model is necessary to accurately predict the broadband sound spectrum. Finally, a rotor noise model is developed for the annular cascade theory. The significance of the Coriolis and centrifugal accelerations, which are not present in the linear cascade rotor formulation, are shown to be important for correctly calculating the aerodynamic and aeroacoustic response. Hence, it is determined that linear cascade theory cannot adequately predict the noise spectrum resulting from unsteady disturbances interacting with a rotating cascade.

▼ The noise produced by the supersonic, high temperature jets that exhaust from military aircraft is becoming a hazard to naval personnel and a disturbance to communities near military bases. Methods to reduce the noise produced from these jets in a practical full-scale environment are difficult. The development and analysis of distributed nozzle blowing for the reduction of radiated noise from supersonic jets is described. Model scale experiments of jets that simulate the exhaust jets from typical low-bypass ratio military jet aircraft engines during takeoff are performed. Fluidic inserts are created that use distributed blowing in the divergent section of the nozzle to simulate mechanical, hardwall corrugations, while having the advantage of being an active control method. This research focuses on model scale experiments to better understand the fluidic insert noise reduction method. Distributed blowing within the divergent section of the military-style convergent divergent nozzle alters the shock structure of the jet in addition to creating streamwise vorticity for the reduction of mixing noise. Enhancements to the fluidic insert design have been performed along with experiments over a large number of injection parameters and core jet conditions. Primarily military-style round nozzles have been used, with preliminary measurements of hardwall corrugations and fluidic inserts in rectangular nozzle geometries also performed. It has been shown that the noise reduction of the fluidic inserts is most heavily dependent upon the momentum flux ratio between the injector and core jet. Maximum reductions of approximately 5.5 dB OASPL have been observed with practical mass flow rates and injection pressures. The first measurements with fluidic inserts in the presence of a forward flight stream have been performed. Optimal noise reduction occurs at similar injector parameters in the presence of forward flight. Fluidic inserts in the presence of a forward flight stream were observed to reduce the peak mixing noise below the already reduced levels by nearly 4 dB OASPL and the broadband shock-associated noise by nearly 3 dB OASPL. Unsteady velocity measurements are used to complement acoustic results of jets with fluidic inserts. Measured axial turbulence intensities and mean axial velocity are examined to illuminate the differences in the flow field from jets with fluidic inserts. Comparisons of laser Doppler measurements with RANS CFD simulations are shown with good agreement. Analysis of the effect of spatial turbulence on the measured quantities is performed. Experimental model scale measurements of jets with and without fluidic inserts over a simulated carrier deck are presented. The model carrier environment consists of a ground plane of adjustable distance below the jet, and a simulated jet blast deflector similar to those found in practice. Measurements are performed with far-field microphones, near-field microphones, and unsteady pressure sensors. The constructive and destructive interference that results from the…

▼ The noise emissions from aircraft negatively impact the quality of life for those in areas around airports. Excess noise levels can cause stress-related complaints, leading to adverse health effects. Although newer aircraft are significantly quieter than older models, aircraft noise pollution remains a problem. Literature suggests that the level of aircraft noise annoyance people experience is equally dependent on the level of disturbance induced by the sound and individuals’ perceived level of their own ability to cope with and control it. Traditionally, noise prediction models are used to determine the noise load around airports. If levels are deemed too high, building restrictions are put in place, and house owners are either bailed out or receive funding for acoustic insulation. However, literature on road traffic noise shows that the design of the environment that surrounds individuals has a great impact on their perception of noise annoyance. For instance, the design of buildings, streets and cities influence the propagation of sound around buildings. This can reduce or amplify the sound levels locally. Furthermore, the presence of natural features, such as trees and moving water, can evoke a more positive auditory sensation in areas exposed to traffic noise. Without changing the sound exposure levels, the sight and proximity of vegetation improves the individuals’ assessment of the soundscape quality and reduces the level of noise annoyance. Like landscapes, the perception of the acoustic environment, or soundscape, is the result of design choices. Nevertheless, the question remains as to whether the design of the built environment can yield a similar effect for aircraft noise. The doctoral research focused on this question, from both an acoustic and soundscape-perception perspective, and comprised four separate studies. The first study presents the results of a systematic in-situ measurement study, in which the sound attenuating effects of buildings exposed to aircraft noise were assessed. In the second chapter, the results from the first study were used to develop and test a method to predict the propagation of aircraft noise around buildings in a numerical acoustic model. The third study used the numerical model to compare the noise attenuation effects of building design parameters, namely height, form and cladding. The fourth chapter explored the perception of aircraft noise in urban areas with or without moving water and vegetation, using virtual-reality. Together, the four studies provide tools that can be used by architects and urban designers to improve the soundscape quality in areas affected by aircraft noise. Depending on the location and local acoustic situation, different alternatives are possible, which are supported by the results presented in this thesis.
