Abstract:
Cochlear implant users are known to have limited access to spatial cues. This study investigated the perception of spatial cues in normal-hearing listeners and cochlear implant simulation users. Perception of spatial cues is assessed for performance in determining the direction of the sound and understanding the speech. The results show that cochlear implant simulation users still have access to spatial cues, just like normal- hearing listeners. Normal-hearing listeners and cochlear implant simulation users can perceive spatial cues in ILD and ITD. Both can accurately identify the direction of the sound (slope ≈ 1.00 and of set ≈ 0.00°). Cochlear implant simulation users can understand sentences as well as normal-hearing listeners (PCW = 113.64 rau) by using the coding strategy SPEAK in all channels or CIS with channel above 8. Perception of spatial cues in normal-hearing listeners and cochlear implant users can be improved by listening with two ears and spatially separating the target-masker position. The largest improvement in spatial cue perception was obtained from the head shadow effect (normal-hearing (NH) = 12.96, cochlear implant simulation users (CI) = 59.02), followed by binaural summation (NH = 5.72, CI = 19, 86) and binaural squelch (NH = 3.76, CI = 7.66).

Abstract:
Purpose: The ability to benefit from spatial separation between target and masker signals is important in multi-sound source listening environments. The goal of this study was to measure the spatial release from masking (SRM) in unilateral cochlear implant (CI) users with bilateral profound hearing loss. We also determined the relationships between the SRMs and the self-reported spatial hearing abilities.Methods: Fourteen unilateral CI users with bilateral profound hearing loss participated in this study. The target sentence was always presented to the front of the listener, and the nonfluctuating speech-shaped noise (SSN) or fluctuating speech noise was either co-located with the target (speech at 0°, noise at 0°, S0N0) or spatially separated at ± 90°. The SRM was quantified as the difference between speech recognition thresholds (SRTs) in the co-located and spatially separated conditions. The self-reported spatial hearing abilities were also measured using validated subjective questionnaires.Results: Overall, the SRTs were lower (better) with SSN than with fluctuating speech noise. When the noise was presented to the non-CI ear (speech at 0°, noise at non-CI ear, S0Nnonci), speech-in-noise recognition was the greatest due to head shadow or better-ear listening effect, resulting in the SRMs of approximately 5~6 dB regardless of noise type. When the noise was given to the CI ear (speech at 0°, noise at CI ear, S0Nci), some individuals exhibited positive SRMs (3~8 dB), while others showed negative SRMs, leading to little SRMs overall. When the SSN was given, subjects with less SRMs (less spatial separation benefits on the objective test) reported greater subjective spatial hearing difficulties.Conclusion: The spatial hearing of unilateral CI users varied by the position of the sound source. Listeners' spatial hearing abilities, which are unpredictable from clinical routine tests, need to be assessed by either objective or subjective measures.

Abstract:
Relationships between extended high-frequency (EHF) thresholds and speech-in-spatialized noise were examined in firefighters with a history of occupational noise and airborne toxin exposure. Speech recognition thresholds were measured for co-located and spatially separated (±90° azimuth) sentences in a competing signal using the Listening in Spatialized Noise–Sentences test. EHF hearing was significantly correlated with the spatial advantage, indicating that firefighters with poorer EHF thresholds experienced less benefit from spatial separation. The correlation between EHF thresholds and spatial hearing remained significant after controlling for age. Deficits in EHF and spatial hearing suggest firefighters may experience compromised speech understanding in job-related complex acoustic environments.

Abstract:
Small timing differences occur when sounds reach one ear before the other, creating interaural phase differences (IPDs). The phase-locked activity in the auditory nerve can, at low frequencies, preserve IPDs. IPDs are used for localising and separating sounds from different directions. Chapters 3, 5, and 6 report three studies of the independent effects of age and sensorineural hearing loss on the temporal processing of sound that aids spatial hearing. Chapters 2 and 4 describe two supporting methodological studies. Chapter 2 compared the duration of training required for stable IPD-discrimination thresholds for two stimulus presentation procedures. The procedure requiring the least training was adopted for subsequent studies. Age and hearing loss are related and both may affect sensitivity to IPDs. Chapter 3 demonstrated that hearing loss, regardless of listener age, is related to poorer sensitivity to IPDs in the temporal fine structure (TFS), but not in the temporal envelope. Chapter 3 also showed that age, independent of hearing loss, is related to poorer envelope-IPD sensitivity at low modulation rates, and somewhat poorer TFS-IPD sensitivity. In Chapter 5, listener age and IPD sensitivity were both compared to subcortical neural phase locking measured through the frequency-following response (FFR). Phase coherence in the envelope-FFR at 145 Hz modulation and in the TFS-FFR deteriorated with age, suggesting less precise phase locking in old age. However, age-related changes to IPD sensitivity were not strongly related to age-related changes in FFR phase coherence. IPD sensitivity declines may be predominantly caused by deterioration of binaural processing independent of subcortical phase locking. Chapter 4 showed that electrodes at the mastoids recorded TFS-FFR generated earlier in the auditory pathway than electrodes from the nape of the neck to forehead, which recorded FFR generated later in the brainstem. However, these electrode montages did not reveal different age- or hearing-loss-related FFR deficits in Chapter 5. Chapter 6 determined whether hearing loss affected the ability to use TFS IPDs to achieve better speech perception. On average, old hearing-impaired listeners gained a small, but significant, benefit from a lateral separation of the speech sources. Replacing the TFS with binaurally in-phase sine waves (removing the TFS IPDs) significantly reduced the benefit of lateral separation. How much a listener benefitted from intact TFS IPDs in speech perception was strongly related to the extent of their hearing loss at low frequencies and their monaural processing of TFS, but not to their ability to discriminate IPDs. In general, this thesis shows that low-frequency hearing loss is associated with poor sensitivity to TFS IPDs and the ability to benefit from them when sounds are laterally separated. The thesis also shows that old age can reduce sensitivity to IPDs and weaken subcortical temporal coding. Although only partly related, these effects are likely to cause problems for old individuals in challenging listening environments.

Full text
Abstract:
Dynamic-range compression is used in hearing devices to reduce the wide range of environmental sound levels into a range better suited to the capability of the impaired ear. Its use is motivated by the fact that the healthy ear itself performs this function, but this natural compression is typically reduced or lost with sensorineural hearing loss. This thesis explores how dynamic-range compression influences aspects of spatial hearing that play an important role in everyday listening. Spatial hearing largely relies on comparing information from the two ears. The first two experiments investigated how spatial perception is affected when compression is applied independently at each ear, as occurs in traditional bilateral hearing-device fittings. This was found to have a variety of possib le adverse effects, such as altering the perceived position of sounds and making them appear more spatially diffuse. The effects are explained in terms of changes to the underlying acoustic cues. Some modern hearing devices incorporate a wireless link, allowing compression to be synchronized across the ears. The third experiment investigated how this might provide an advantage when listening to speech in the presence of a spatially separated noise. It was found that a small to moderate benefit was obtained, compared to unlinked compression, and that this was realized th rough changes to the monaural signal at the ear that had the more favourable ratio of speech-to-noise energy. The fourth experiment tested whether the natural compression that occurs within the healthy cochlea directly affects the use of the relative level difference between the two ears as a spatial cue. Contrary to the experimental hypothesis, it was found that the potency of this cue changes little as the overall sound intensity is varied over a wide range, raising interesting questions about how this cue is evaluated at a neural level.

This thesis explores the possibilities of spatial hearing in relation to sound perception, and presents three acousmatic compositions based on a musical aesthetic that emphasizes this relation in musical discourse. The first important characteristic of these compositions is the exclusive use of sine waves and other time invariant sound signals. Even though these types of sound signals present no variations in time, it is possible to perceive pitch, loudness, and tone color variations as soon as they move in space due to acoustic processes involved in spatial hearing. To emphasize the perception of such variations, this thesis proposes to divide a tone in multiple sound units and spread them in space using several loudspeakers arranged around the listener. In addition to the perception of sound attribute variations, it is also possible to create rhythm and texture variations that depend on how sound units are arranged in space. This strategy permits to overcome the so called "sound surrogacy" implicit in acousmatic music, as it is possible to establish cause-effect relations between sound movement and the perception of sound attribute, rhythm, and texture variations. Another important consequence of using sound fragmentation together with sound spatialization is the possibility to produce diffuse sound fields independently from the levels of reverberation of the room, and to create sound spaces with a certain spatial depth without using any kind of artificial sound delay or reverberation.
Esta tese explora as possibilidades da Audição Espacial em relação à percepção do som e apresenta três composições acusmáticas baseadas numa estética musical que enfatiza esta relação e a incorpora como uma parte do seu discurso musical. A primeira característica importante destas composições é a utilização exclusiva de sinusóides e de outros sinais sonoros invariáveis no tempo. Embora estes tipos de sinais não apresentem variações no tempo, é possível percepcionar variações de altura, intensidade e timbre assim que estes se movem no espaço, devido aos processos acústicos envolvidos na audição espacial. Para enfatizar a percepção destas variações, esta tese propõe dividir um som em múltiplas unidades e espalhá-las no espaço utilizando vários monitores dispostos à volta da plateia. Além da percepção de variações de características do som, também é possível criar variações de ritmo e de textura que dependem de como os sons são dispostos no espaço. Esta estratégia permite superar o problema de “sound surrogacy” implícito na música acusmática, uma vez que é possível estabelecer relações causa-efeito entre o movimento do som e a percepção de variações de características do som, variações do ritmo e textura. Outra consequênça importante da utilização da fragmentação com a espacialização do som é a possibilidade de criar campos sonoros difusos, independentemente dos níveis de reverberação da sala, e de criar espaços sonoros com uma certa profundidade, sem utilizar nenhum tipo de delay ou reverberação artificiais.

Abstract:
This thesis provides an overview of work conducted to investigate human spatial hearing in situations involving multiple concurrent sound sources. Much is known about spatial hearing with single sound sources, including the acoustic cues to source location and the accuracy of localisation under different conditions. However, more recently interest has grown in the behaviour of listeners in more complex environments. Concurrent sound sources pose a particularly difficult problem for the auditory system, as their identities and locations must be extracted from a common set of sensory receptors and shared computational machinery. It is clear that humans have a rich perception of their auditory world, but just how concurrent sounds are processed, and how accurately, are issues that are poorly understood. This work attempts to fill a gap in our understanding by systematically examining spatial resolution with multiple sound sources. A series of psychophysical experiments was conducted on listeners with normal hearing to measure performance in spatial localisation and discrimination tasks involving more than one source. The general approach was to present sources that overlapped in both frequency and time in order to observe performance in the most challenging of situations. Furthermore, the role of two primary sets of location cues in concurrent source listening was probed by examining performance in different spatial dimensions. The binaural cues arise due to the separation of the two ears, and provide information about the lateral position of sound sources. The spectral cues result from location-dependent filtering by the head and pinnae, and allow vertical and front-rear auditory discrimination. Two sets of experiments are described that employed relatively simple broadband noise stimuli. In the first of these, two-point discrimination thresholds were measured using simultaneous noise bursts. It was found that the pair could be resolved only if a binaural difference was present; spectral cues did not appear to be sufficient. In the second set of experiments, the two stimuli were made distinguishable on the basis of their temporal envelopes, and the localisation of a designated target source was directly examined. Remarkably robust localisation was observed, despite the simultaneous masker, and both binaural and spectral cues appeared to be of use in this case. Small but persistent errors were observed, which in the lateral dimension represented a systematic shift away from the location of the masker. The errors can be explained by interference in the processing of the different location cues. Overall these experiments demonstrated that the spatial perception of concurrent sound sources is highly dependent on stimulus characteristics and configurations. This suggests that the underlying spatial representations are limited by the accuracy with which acoustic spatial cues can be extracted from a mixed signal. Three sets of experiments are then described that examined spatial performance with speech, a complex natural sound. The first measured how well speech is localised in isolation. This work demonstrated that speech contains high-frequency energy that is essential for accurate three-dimensional localisation. In the second set of experiments, spatial resolution for concurrent monosyllabic words was examined using similar approaches to those used for the concurrent noise experiments. It was found that resolution for concurrent speech stimuli was similar to resolution for concurrent noise stimuli. Importantly, listeners were limited in their ability to concurrently process the location-dependent spectral cues associated with two brief speech sources. In the final set of experiments, the role of spatial hearing was examined in a more relevant setting containing concurrent streams of sentence speech. It has long been known that binaural differences can aid segregation and enhance selective attention in such situations. The results presented here confirmed this finding and extended it to show that the spectral cues associated with different locations can also contribute. As a whole, this work provides an in-depth examination of spatial performance in concurrent source situations and delineates some of the limitations of this process. In general, spatial accuracy with concurrent sources is poorer than with single sound sources, as both binaural and spectral cues are subject to interference. Nonetheless, binaural cues are quite robust for representing concurrent source locations, and spectral cues can enhance spatial listening in many situations. The findings also highlight the intricate relationship that exists between spatial hearing, auditory object processing, and the allocation of attention in complex environments.

Perception of sound laterality (left-right angle) is mediated by both interaural time differences (ITD) and interaural level differences (ILD). Previous localization studies in anechoic settings consistently show that low-frequency ITDs dominate perception of source laterality. However, reverberant energy differentially degrades ITDs and ILDs; the effects of room reflections on the perceptual weight given to ITDs and ILDs are not well understood. Here, we tested the hypothesis that high-frequency envelope ITD cues are important for spatial judgments in reverberant rooms by measuring the perceived laterality of high-pass, low-pass and broadband sounds. Results show that when ILD cues and ITD envelope cues are both available, reverberant energy has the smallest effect on localization of high-pass stimuli. When ILD cues are set to zero, localization of high-pass stimuli with strong envelopes (i.e. click trains and speech tokens) is also minimally affected by reverberant energy; however, as envelope modulation is reduced, subjects show increasing localization bias, responding towards the center. Moreover, for stimuli with strong envelopes, subjects with better modulation detection sensitivity are affected less by the addition of reverberant energy. These results suggest that, in contrast to in anechoic space, high-frequency envelope ITD cues influence localization in reverberant settings.

The purpose of this study was to ascertain whether there was indeed a relationship between processing strategy (temporal or spatial processing) and internal speech. The task utilized for the study, was constructed from the tasks used by O'Connor and Hermeiin (1973a), Conrad (1979), and Booth(1982). It was then administered to 71 hearing impaired and 74 hearing subjects. The groups were matched according to vocabulary level, rather than chronological age. Results strongly indicate that there is indeed a relationship between temporal processing and internal speech for hearing threshold level groups. Age was shown to be a determining factor for choice of processing strategy for both hearing and hearing impaired groups. Severity of hearing loss was not found to have an effect on processing strategy. Profoundly deaf children, and hearing children did not demonstrate a preferred processing strategy. It would seem necessary to continue to investigate the relationship between processing strategy and internal speech. Perhaps looking at individuals rather than heterogeneous groups would yield additional information.

Abstract:
In this thesis I attempt to explain mechanisms of neuronal coding in the auditory system as a form of adaptation to statistics of natural stereo sounds. To this end I analyse recordings of real-world auditory environments and construct novel statistical models of these data. I further compare regularities present in natural stimuli with known, experimentally observed neuronal mechanisms of spatial hearing. In a more general perspective, I use binaural auditory system as a starting point to consider the notion of function implemented by sensory neurons. In particular I argue for two, closely-related tenets: 1. The function of sensory neurons can not be fully elucidated without understanding statistics of natural stimuli they process. 2. Function of sensory representations is determined by redundancies present in the natural sensory environment. I present the evidence in support of the first tenet by describing and analysing marginal statistics of natural binaural sound. I compare observed, empirical distributions with knowledge from reductionist experiments. Such comparison allows to argue that the complexity of the spatial hearing task in the natural environment is much higher than analytic, physics-based predictions. I discuss the possibility that early brain stem circuits such as LSO and MSO do not \"compute sound localization\" as is often being claimed in the experimental literature. I propose that instead they perform a signal transformation, which constitutes the first step of a complex inference process. To support the second tenet I develop a hierarchical statistical model, which learns a joint sparse representation of amplitude and phase information from natural stereo sounds. I demonstrate that learned higher order features reproduce properties of auditory cortical neurons, when probed with spatial sounds. Reproduced aspects were hypothesized to be a manifestation of a fine-tuned computation specific to the sound-localization task. Here it is demonstrated that they rather reflect redundancies present in the natural stimulus. Taken together, results presented in this thesis suggest that efficient coding is a strategy useful for discovering structures (redundancies) in the input data. Their meaning has to be determined by the organism via environmental feedback.

Abstract:
In binaural hearing aids, several beamforming algorithms can be used. These beamformers aim to enhance the target speech signal and preserve the binaural cues of the target source (e.g. with constraints on the target). However, the binaural cues of the other directional sources as well the background noise are often lost after processing. This affects the global impression of the acoustic scene, and it limits the perceptual separation of the sources by the hearing aids users. To help the hearing aids users to localize all the sound sources, it is important to keep the binaural cues of all directional sources and the background noise. Therefore, this work is devoted to find the best trade-off between the noise/interferers reduction and the cues preservations not only for the directional interferers but also for the background noise based on selection and mixing processes. In this thesis, some classification decision algorithms, which are based on different criteria such as the power, the power difference, and the coherence, are proposed to complete the selection and mixing processes. Simulations are completed using recorded signals provided by a hearing aid manufacturer to validate the performance of the proposed algorithm under different realistic acoustic scenarios. After detailed testing using different complex acoustic scenarios and different beamforming configurations, the results indicate that some of the proposed classification decision algorithms show good promise, in particular the classification decision algorithm based on coherence.

Abstract:
Acoustic processing of audio and sonar by animals involves the temporal as well as spatial aspects of an incoming signal. We can presume that a bat, for example, acquires an entire spatial picture of its surroundings from its sonar returns rather than some empty series of blips that the untrained human ear derives from the sound of a ship’s sonar; in effect the bat sees with its ears [1]. The barn owl makes equally impressive use of hearing with passive sonar to locate and capture prey in the dark. In these cases, and in speech recognition by humans, the sequential nature of the information plays an essential role.

Abstract:
Infrasound—that is, acoustic waves with frequencies below the threshold of human hearing—has historically been used to detect and locate distant explosive events over global ranges (≥1,000 km). Simulations over these ranges have traditionally relied on large-scale, synoptic meteorological information. However, infrasound propagation over shorter, local ranges (0–100 km) may be affected by smaller, mesoscale meteorological features. To identify the effects of these mesoscale meteorological features on local infrasound propagation, simulations were conducted using the Weather Research and Forecasting (WRF) meteorological model to approximate the meteorological conditions associated with a series of historical, small-scale explosive test events that occurred at the Big Black Test Site in Bovina, Mississippi. These meteorological conditions were then incorporated into a full-wave acoustic model to generate meteorology-informed predictions of infrasound propagation. A series of WRF simulations was conducted with varying degrees of horizontal resolution—1, 3, and 15 km—to investigate the spatial sensitivity of these infrasound predictions. The results illustrate that convective precipitation events demonstrate potentially observable effects on local infrasound propagation due to strong, heterogeneous gradients in temperature and wind associated with the convective events themselves. Therefore, to accurately predict infrasound propagation on local scales, it may be necessary to use convection-permitting meteorological models with a horizontal resolution ≤4 km at locations and times that support mesoscale convective activity.

Abstract:
Nesta edição da revista, a presente seção conta com cinco resenhas de livros (também chamadas de book reviews). E há uma novidade: as duas primeiras resenhas foram escritas pelos próprios autores dos livros. As outras três resenhas ficaram a cargo dos editores do número 53. Outra novidade é que todas elas estão também disponíveis em língua inglesa (elas começam na página 7). Lembramos que as resenhas são escritas de forma abreviada e concisa, de modo a resumir o conteúdo dos livros (em assuntos relacionados com as diversas ciências que envolvem acústica, vibrações e áudio) e trazer informações acerca dos autores (para contextualizar ainda mais as obras). Para este número trazemos as resenhas dos seguintes livros: Sound-Politics in São Paulo Autor: Leonardo Cardoso | Oxford Press, 2019 Dinâmica Aplicada Autor: Roberto A. Tenenbaum | Editora Manole, 2016 (4 ed.) Acústica nos Edifícios Autor: Jorge Patrício | Publindústria, 2018 (7 ed.) Understanding Acoustics: An Experimentalist’s View of Sound and Vibration Autor: Steven L. Garret | Springer, 2020 Spatial Hearing: The Psychophysics of Human Sound Localization Autor: Jens Blauert | MIT Press, 1996 (Rev. Ed.). Leonardo Cardoso, professor na Texas A&M University, apresenta seu livro sobre política sonora em São Paulo. Roberto Tenenbaum, professor da UFSM, apresenta a quarta edição de sua obra importante na compreensão de Acústica e Vibrações. Em seguida, é apresentado um dos livros de Jorge Patrício, referência portuguesa em Acústica de Edificações. O quarto livro é o “Entendendo a acústica”, de autoria de Steven Garret. Por último, o livro clássico do prof. alemão Jens Blauert, “Áudio espacial”, é apresentado. Esperamos que a leitura das resenhas ofereça as primeiras compreensões/impressões sobre as obras e desperte vontade de conhecê-las por inteiro: uma excelente maneira de ampliar o conhecimento e de se manter atualizado.
