  • Propagation of Underwater Noise from an Offshore Seismic Survey in
           Australia to Antarctica: Measurements and Modelling
    • Authors: Alexander Gavrilov
      Abstract: An offshore seismic survey was conducted over the western edge of the continental shelf in Bass Strait in 2006. Underwater noise from this survey was recorded on an autonomous sound recorder deployed in the Southern Ocean on the Antarctic continental slope. Sound emission and propagation models were verified by experimental measurements using parameters and position of the airgun array and characteristics of the underwater sound channel. A parabolic equation approximation method was used to calculate the sound field over the continental slope of Australia, and then, a normal mode model was employed to account for the transmission loss due to sound scattering by surface waves south of the polar front. The numerical predictions are consistent with the measurement results within a few dBs for the sound exposure and energy spectral density levels. It is also demonstrated by measurements and modelling that the best coupling of a near-surface sound source with the deep underwater sound channel takes place when the source is located over the continental slope at a sea depth of about half of the channel’s axis depth. The model can be used to predict masking effects of man-made underwater noise on the communication environment of marine mammals in Antarctica.

  • Two-Step Inversion of Geoacoustic Parameters with Bottom Reverberation and
           Transmission Loss in the Deep Ocean
    • Authors: Kunde Yang; Liya Xu; Qiulong Yang; Ganxian Li
      Abstract: The parameters of deep ocean sediments are relevant for accurately predicting the sound field; however, it is difficult to measure the parameters in situ. Most inversion methods used in shallow water are inapplicable in the deep ocean because of the considerable differences in propagation characteristics. At present, no method for simultaneously obtaining sound speed, density, and attenuation that considers the sensitivity of sediment parameters is yet available. This study proposes a two-step inversion of geoacoustic parameters in the deep ocean. On the basis of the half-space model, the decline tendency of bottom reverberation level with travel time is used for the inversion of sound speed and density, whereas transmission loss is used for inversion of attenuation. Inversion results can be practical for acoustic applications when this method is used. Experimental data from the South China Sea in the summer of 2014 are processed during the inversion process. The sediment parameters obtained from the inversion process are close to the laboratory-measured sampling values and may be used to predict the sound field in various applications, such as in transmission loss in the deep ocean.

  • Comparison of the Effects on Memory Tasks of Babble and Broadband Noise
    • Authors: Brett R. C. Molesworth; Marion Burgess; Chloe Wilcock
      Abstract: The comparative effects on both working memory and recognition memory of the same A-weighted noise levels of background noise, typically of that present in many transportation work areas, were investigated (55 and 65 dBA). One noise was a babble, multi-talker incomprehensible speech and representative of the many work areas dealing with administrative tasks. The other noise was broadband and similar to services and machinery noise. Forty participants, half non-native English speakers, were asked to complete three different working memory tests (linguistics, grammatical reasoning and mathematics) and one recognition memory test (cued recall) in the presence of the two types of noise at the two different levels. Broadband noise at 65 dBA was found to adversely affect recall by as much as 15%. The native language advantage was only evident with the linguistic working memory task. The findings highlight the interplay between type of noise, level of noise, demand of task, and language background of the person completing the task, and also the limitations of the use of dBA alone for assessment of acceptability of a workspace.

  • Underwater Sound Source Localization by EMD-Based Maximum Likelihood
           Method
    • Authors: B Marxim Rahula Bharathi; A R Mohanty
      Abstract: The underwater object localization is important in defense, underwater biological and environmental applications. Localization using a passive sonar system is a challenging task. It is more challenging when the source and receivers are in the reverberant environment. Time delay estimation (TDE)-based localization is a well-known technique to localize source for last few decades. In this work, empirical mode decomposition maximum likelihood (EMD ML TDE) method is used to estimate the time delay in a reverberant environment. The sound source location is estimated by intersecting spherical surfaces from the time delay. The experimental results prove that EMD ML time delay estimation method is effective to localize a sound source in a reverberant environment.

  • Using Petrel II Glider to Analyze Underwater Noise Spectrogram in the
           South China Sea
    • Authors: Lu Liu; Ling Xiao; Shi-Quan Lan; Ting-Ting Liu; Guo-Li Song
      Abstract: In this paper, a Petrel II autonomous underwater glider (AUG) was used to analyze underwater noise spectrogram in the South China Sea. For ocean observations, AUG has an excellent performance such as being efficient in all weather conditions, lasting for long time periods, being able to be remote controlled, which creates favorable conditions for analyzing underwater noise characteristics. In order to measure the underwater noise, a newly developed and customized underwater passive acoustic monitoring system was firstly installed on the Petrel II glider and tested in the South China Sea trial in August 2016. The observation data at a depth of 1000 meters range were taken as the research object and were used to analyze the noise levels over a long period through the method of the short-time Fourier transform. At the same time, the noise data have been compared in time to the actions of the glider during the sea trial. However, AUGs also have limitations such as undesired instrument and flow noise. By adopting the step-by-step method, these self-noise data of Petrel II glider were acquired and analyzed quantitatively, and the basic characteristics of self-noise under different working conditions are depicted. Removing the corresponding self-noise, the noise data at different depths measured by the Petrel II glider could be used to estimate underwater ambient noise levels across depth.

    • Authors: Gorica Micic; Branko Zajamsek; Leon Lack; Kristy Hansen; Con Doolan; Colin Hansen; Andrew Vakulin; Nicole Lovato; Dorothy Bruck; Ching Li Chai-Coetzer; Jeremy Mercer; Peter Catcheside
      Abstract: Adequate sleep is important for good health and well-being, and inadequate sleep leads to impaired attention and performance. Persistent poor sleep is also associated with cognitive and metabolic impairment, cardiovascular problems and diminished psychological well-being. Recent growth in wind farm developments has been associated with community complaints regarding sleep disturbance, annoyance and a range of health issues that some attribute to wind farms. Wind turbines create aerodynamic and mechanical noise that, if sufficiently loud, has the potential to disturb residents’ sleep, particularly for those living in close proximity. According to the World Health Organisation (WHO), noise effects on sleep are expected to occur with outside noise levels > 40 dB (A). On the other hand, the WHO guidelines also state that “when prominent low-frequency components are present, measures based on A-weighting are inappropriate”, so uncertainty remains regarding which alternative noise measures and noise limits are most appropriate to mitigate community impacts of wind farm noise on sleep. In Australia, dwellings are typically located > 1 km from the nearest wind turbine where wind farm noise becomes more biased towards lower frequencies ( \(\le \) 200 Hz) at low sound pressure levels ( \(<\sim \)  40 dB (A) outside) that may or may not be audible inside a dwelling. Nevertheless, as with any environmental noise, wind farm noise has the potential to disturb sleep, via frequent physiological activation responses and arousals affecting the micro-structure of sleep, and the overall macro-structure of sleep, including total sleep time potentially reduced by difficulty falling asleep and returning to sleep following awakenings for whatever reason. Over time, chronic insomnia could potentially develop in individuals with greater sensory acuity and/or those prone to annoyance from environmental noise. However, it is unclear if and how much sleep is disturbed by the relatively low sound pressure levels relevant to wind turbine noise. Good empirical evidence to investigate these plausible mechanisms is sparse. In this paper, we describe the psychophysiological mechanisms that underlie sleep disturbance in response to noise, review current evidence regarding the effects of wind farm noise on sleep, evaluate the quality of existing evidence and identify evolving research in this area.

  • Clarifications on the Design and Interpretation of Conclusions from Health
           Canada’s Study on Wind Turbine Noise and Health
    • Authors: David S. Michaud; Katya Feder; Sonia A. Voicescu; Leonora Marro; John Than; Mireille Guay; Eric Lavigne; Allison Denning; Brian J. Murray; Shelly K. Weiss; Paul Villeneuve
      Abstract: It has been extensively communicated that Health Canada’s Community Noise and Health Study (CNHS) did not find positive associations between wind turbine noise (WTN) levels and any of the evaluated health outcomes, beyond an increase in the prevalence of high annoyance toward several wind turbine features. The authors emphasize that this general conclusion remains bound by the study strengths and limitations. Following the publication of the CNHS findings, there has been interest among some individuals to present alternative interpretations of the results originally reported by Michaud et al. (J Acoust Soc Am 139(3):1443–1454, 2016. https://doi.org/10.1121/1.4942391). While recognizing the importance of independent scientific re-evaluation and/or reinterpretation, this commentary serves to clarify and, where necessary, correct some of the information put forward by others. One factor that has been re-evaluated by external stakeholders is the subsample of participants that comprise the lowest WTN category. In their reanalysis, they have eliminated this category, or introduced alternative comparative data. This paper identifies substantial issues associated with the re-evaluation put forth. To thoroughly address these issues and to avoid further confusion or misinterpretation, the authors of the CNHS provide a comparison between the CNHS health condition prevalence data and nationally representative health-based surveys conducted in Canada during the same calendar year. In addition, this paper responds to comments received to date on the CNHS, including the study’s age range, the generalization of findings, the provision of raw data, and conclusions on the association between WTN level and health.

  • Study on the Optimization of the Distribution of Absorbing Material on a
           Noise Barrier
    • Authors: Leilei Chen; Wenchang Zhao; Xiaohui Yuan; Baochun Zhou
      Abstract: Noise barriers have been widely used to decrease the transportation noise. How to utilize limited structure and material to achieve the environmental requirements for noise control is an important research topic. This research combines the use of boundary element method and SIMP to generate an acoustic topology optimization method and applies this optimization method to optimization distribution of absorbing material installed on the noise barrier’s edges. Optimality criteria method is used to update the design variables and look for the final optimal solution. A new material interpolation scheme for acoustic problems based on SIMP is given, where the interpolation variable is not real structural density used in conventional SIMP, but fictitious material density deciding the normalized surface admittance. It is noteworthy that gray elements exist in the acoustic optimization analysis based on SIMP. However, a modified method based on a smoothed Heaviside function is applied to eliminate the gray elements. In order to demonstrate the validity and efficiency of the proposed algorithm in this paper, vertical barrier and T-shaped barrier with two wells are used for the numerical analysis, respectively.

  • Adaptive Matched Field Processing for Source Localization Using Improved
           Diagonal Loading Algorithm
    • Authors: Phu Ninh Tran; Khanh Dang Trinh
      Pages: 325 - 330
      Abstract: Matched field processing (MFP) has been a method widely applied for shallow underwater target localization, which is a critical issue in underwater acoustic. To enhance the efficiency of conventional MFP methods, different adaptive MFP algorithms have been developed; the white noise constraints (WNC) MFP or diagonal loading (DL) algorithm is such a typical one. The WNC or DL one has been considered to be the most desirable method because it is more robust to environment mismatch in practical in comparison with the minimum-variance distortionless response MFP algorithm, a popular high-resolution method. Although having exceptional ability to localize underwater sources in mismatch scenarios, the DL method has still been not reach high resolution in certain cases. In the paper, we proposed an adaptive method known as improved diagonal loading algorithm to make an increase in the resolution and the peak background rate in the ambiguity surface of source localization results in comparison with DL one. The proposed algorithm works by adding one more parameter that is adjusted in the steering vector of the DL algorithm. The simulation results show that the new algorithm attains better beamforming performance in terms of high resolution than the existing adaptive MFP algorithms in the case of environmental mismatch caused by noise effects and the limitation of the snapshots.

  • Health Effects Related to Wind Turbine Sound, Including Low-Frequency
           Sound and Infrasound
    • Authors: Irene van Kamp; Frits van den Berg
      Abstract: A narrative review of observational and experimental studies was conducted to assess the association between exposure to wind turbine sound and its components and health effects in the general population. Literature databases Scopus, Medline and Embase and additional bibliographic sources such as reference sections of key publications and journal databases were systematically searched for peer-reviewed studies published from 2009 to 2017. For the period until early 2015 only reviews were included, while for the period between January 2015 and January 2017 all relevant publications were screened. Ten reviews and 22 studies met the inclusion criteria. Most studies examined subjective annoyance as the primary outcome, indicating an association between exposure levels and the percentage highly annoyed. Sound from wind turbines leads to a higher percentage of highly annoyed when compared to other sound sources. Annoyance due to aspects, like shadow flicker, the visual (in) appropriateness in the landscape and blinking lights, can add to the noise annoyance. There is no evidence of a specific effect of the low-frequency component nor of infrasound. There are indications that the rhythmic pressure pulses on a building can lead to additional annoyance indoors. Personal characteristics such as noise sensitivity, privacy issues and social acceptance, benefits and attitudes, the local situation and the conditions of planning a wind farm also play a role in reported annoyance. Less data are available to evaluate the effects of wind turbines on sleep and long-term health effects. Sleep disturbance as well as other health effects in the vicinity of wind turbines was found to be related to annoyance, rather than directly to exposure.

      Abstract: In the April 2017 edition of this journal, the Author published a theoretical Technical Note in the peer-reviewed section of the journal. Commentary on that Technical Note was provided in Forum section of that same issue by Jeff Parnell of the NSW Department of Planning and Environment. The primary concerns were that simplification of the method could result in underestimation of noise impacts. This reply aims to allay some of those concerns.

  • Vertical Correlation of the Acoustic Field in Deep Water Measured with
           Explosive Sources
    • Authors: Hui Li; Kunde Yang; Zhixiong Lei; Rui Duan
      Abstract: In this paper we report the measurement and analysis on vertical correlations of acoustic signals received by a vertical line array deployed near the sea bottom in deep water. The source data were from one calibration experiment of sound exposure level of explosive charges. The source–receiver range is about 17 km. The sound transmission duct is the well-known reliable acoustic path (RAP). The vertical correlation coefficients are estimated at center frequencies of 300, 600, 1000 and 1500 Hz with 1/3 octave bands. Two types of explosive charges are used with nominal source depths of 50 and 300 m, respectively. The variation of vertical correlation coefficients strongly relies on source depth and center frequency. For each scene, ten groups of experiment data exhibit uniform variation of vertical correlation coefficients with fractional differences due to the fluctuation of ocean waveguide. Besides, the noise-free numerical modeling results reach good agreements with the measured ones, which reflect the stability of RAP as a sound transmission duct in the space/frequency domain. Due to the obvious arrival structures of rays, the theoretical solution of vertical correlation coefficient is derived based on the ray theory. At last, the effects of source–receiver geometry on the variability of vertical correlation are discussed.

  • Design and Validation of a Simulator Tool Useful for Designers and Policy
           Makers in Urban Sound Planning
    • Authors: Carlos Villazón Laso; César Asensio; Ignacio Pavón
      Abstract: Currently, the design of the urban soundscapes has been approached from distinct perspectives, which include, in all cases, the evaluation of how people perceive sound. An effective way to know how people experience an acoustic environment is through the use of simulators, where the inhabitants can design and establish their preferred sound levels. Making these tools available to different urban specialists, so they can be applied in individual common working environments, will allow them to be incorporated into the distinct stages of urban design, considerably improving solutions that promote more pleasant and restorative soundscapes for users. This paper describes the design and testing of a software based on a portable simulation tool whose function is to evaluate the acceptability of a variety of environmental noise sources categorized in four groups—water, birds, music and people. The experiment also evaluates the acceptability of these sounds sources with and without traffic noise mixed into the replayed sound. In order to validate it, two experiments with separate groups of people have been applied in two different places. With the exception of the “people” group of sounds, the results showed no correlation between sound level and acceptability, vibrancy, calmness both with and without the traffic and also the same preferred sounds were chosen in both places. These results suggest that it is possible to make prior participatory listening tests out of the laboratory. Finally, the participants commented that this experience improves their understanding of the acoustic environment and makes them aware of it.

  • Wind Farm Noise Uncertainty: Prediction, Measurement and Compliance
           Assessment
    • Authors: Kristy L. Hansen; Branko Zajamsek; Colin H. Hansen
      Abstract: In most jurisdictions containing wind farms, base noise limits have been set by local regulatory authorities, with the intention of protecting the amenity of surrounding communities. It is a standard requirement that during the planning process for a new wind farm, the developer demonstrates that the proposed wind farm will comply with the relevant limits. At present, results from noise prediction models are commonly presented without uncertainty values, despite the fact that simplifications and approximations have been made in the models. Therefore, when prediction models indicate that the wind farm will generate noise within 3 dB of base noise limits, it is likely that these limits will be exceeded. Despite the fact that regulatory authorities often require that compliance measurements are taken to validate predictions of wind farm noise, it is very difficult to make substantial changes to noise emissions, without a corresponding reduction in electrical power output. Current methods of compliance assessment do not provide an indication of the amount of time that wind farms exceed allowable noise limits as they focus on ‘average’ levels only. Therefore, it is possible for wind farms to exceed allowable limits on a regular basis, and by significant margins. Hence, a more conservative approach is warranted during wind farm noise prediction and it is proposed that the upper level of the uncertainty estimate of the prediction model should not be permitted to exceed the allowable level.

  • Sound Quality Experiments in a Student Hostel with Newly Designed Sonic
           Crystal Window
    • Authors: Hsiao Mun Lee; Long Bin Tan; Kian Meng Lim; Heow Pueh Lee
      Abstract: A new design of sonic crystal window was designed to replace the existing glass louver window in a student hostel in NUS in order to achieve good balancing of natural ventilation, daylighting and noise mitigation. Numerical studies were performed on the SC window to confirm the window design. The noise level inside the room was measured using sound quality head and torso simulator for simulated white noise, pink noise and construction noise on the ground floor as well as the actual environmental noise. Ten human subjects were asked to evaluate the construction noise and environmental noise inside the room. Psychoacoustics analyses were also performed on these two types of noises. The SC window was designed such that it can attenuate the noise at frequency range of traffic noise. The SC window was able to attenuate extra 4.59 and 9.40 dBA of white noise at full frequency range and frequencies ranging from 700 to 1400 Hz, respectively. The overall amount of pink noise attenuated by the SC window was similar to that of white noise. It can be concluded that gender affected the human subjective perception toward construction noise. All human subjects felt that the degree of annoyance for environmental noise passing through the glass louver window was higher than the SC window. The SC window would successfully reduce the loudness of the construction and environmental noises compared to the glass louver window.

  • Reducing the Ambulance Siren Noise for Distant Auscultation of the Lung
           Sound
    • Authors: Bing-Yuh Lu; Meng-Lun Hsueh; Huey-Dong Wu
      Abstract: Ambulance sirens sound very loud for transportation safety. However, loud sounds interfere with the auscultation of lung sounds. This study proposed an auscultation system that includes (1) an ACER Aspire 17 notebook as a server; (2) a smart mobile as a wireless hotspot (HwaWei Amazing A6); and (3) an ACER Aspire 5 notebook as a client. National Instruments data socket software gives read and write privileges to the IP addresses of the server and client. This real-world distant auscultation system works. The real-time adaptive filter reduced siren noise of 60 dB in power intensity. Surprisingly, a previous simulation of the adaptive filter had performed a noise reduction of 60 dB. Therefore, this real-time remote auscultation system is a reliable device for the ambulance service.

  • The Tympanal Recess of the Cetacean Cochlea: Function and Evolution
    • Authors: Travis Park; Erich M. G. Fitzgerald; Alistair R. Evans
      Abstract: Cetaceans (whales and dolphins) primarily use sound to communicate and hunt for prey. Their auditory anatomy is highly specialised, but much about its function remains unknown. In particular, a feature of the cochlea known as the tympanal recess present in some mysticetes (baleen whales) and odontocetes (toothed whales) has defied functional explanation. Here, we present and discuss several hypotheses that may clarify the function and evolution of the tympanal recess. One potential function in particular, the vibroacoustic duct mechanism, seems most plausible although further work is needed to test the hypothesis, which hints at the possibility of sperm whales and beaked whales being able to detect both high and low frequencies.

  • High-Frequency Modulated Signals Recorded Off the Antarctic Peninsula
           Area: Are Killer Whales Emitting Them'
    • Authors: M. V. Reyes Reyes; S. Baumann-Pickering; A. Simonis; M. L. Melcón; J. Trickey; J. Hildebrand; M. Iñíguez
      Abstract: High-frequency modulated signals with a stereotyped down-swept contour were recorded in the northwestern Antarctic Peninsula using an autonomous recorder and a towed hydrophone array. Signals have a mean start frequency at 21.6 kHz, end frequency at 15.7 kHz, −10 dB bandwidth of 5.9 kHz, and duration of 65.2 ms. Bouts of signals were generally recorded with a median inter-signal interval of 2.1 s. HFM signals partially modulated in the non-ultrasonic range similar to the ones described in this paper have already been reported for killer whales in the North Pacific, Western South Atlantic and Western Australian coast. The HFM signals were recorded in the presence of other odontocete sounds such as whistles, echolocation clicks and burst-pulsed sounds. The similarities of these sounds with vocalizations described for killer whales in the Western Australian coast lead us to strongly believe that the described HFM signals were produced by Antarctic killer whales. This paper described for the first time HFM signals in Antarctica and discussed evidence suggesting that Antarctic type A killer whales are the most probable candidates to produce such signals. However, a visual confirmation is still needed and the function of the HFM signals remains unknown.
