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-discrimina

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 investiga

Doutoramento em Música<br>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 h

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 dire

The experiments reported in this thesis investigated the bases of the difficulties that older adults report when trying to listen to what one person is saying when many other people are speaking at the same time.

When talkers started speaking one at a time, listeners could hear out a target phrase that was less intense than overlapping masker phrases. When talkers started speaking in pairs, listeners could attend to a less intense target phras

In bats, the directivity patterns for reception are shaped by the surface geometry of the pinnae. Since many bat species are capable of large ear deformations, these beampatterns can be time-variant.

Abstract:

The Short-Time Target Cancellation (STTC) algorithm, developed as part of this dissertation research, is a “Cocktail Party Problem” processor that can boost speech intelligibility for a target talker from a specified “look” direction, while suppressing the intelligibility of competing talkers. The algorithm holds promise for both automatic speech recognition and assistive listening device applications. The STTC algorithm operates on a frame-by-frame basis, leverages the computational efficiency of the Fast Fourier Transform (FFT), and is designed to run in real time. Notably, performance in ob

Abstract:

Normal-hearing listeners can locate sound sources, using binaural cues for azimuth angle. These binaural differences in the timing and intensity of sound arriving at the two ears, interaural time differences (ITDs) and interaural intensity differences (IIDs), also support selective listening in multi-talker environments. Auditory-brainstem neurons of the medial superior olive (MSO) and lateral superior olive (LSO) encode ITD in the envelope of sound (ITDENV) and in the temporal fine structure of low-frequency sound (ITDTFS); LSO neurons encode IID. Bilateral-cochlear-implant (bCI) listeners ge

Abstract:

Dans le cas de perte auditive, la localisation spatiale est amoindrie et vient entraver la compréhension de la parole et ce, malgré le port de prothèses auditives. La présente étude modifie la forme de l’oreille externe d’individus à l’aide de silicone afin d’induire des changements aux indices spectraux (HRTFs), similaires à ceux causés par des prothèses auditives, et d’explorer les mécanismes perceptifs (visuel, spectral, ou tactile) permettant d’alterner d’un nouvel ensemble à l’ensemble originel de HRTFs une fois les prothèses enlevées. Les résultats démontrent que les participants s’adapt

Abstract:

Об’єктом дослідження є стан просторового орієнтування в учнів зі зниженим слухом. Предмет дослідження – процес розвитку просторового орієнтування в учнів початкових класів зі зниженим слухом засобами адаптивного фізичного виховання. Мета дослідження – теоретично обґрунтувати й експериментально перевірити ефективність використання засобів адаптивного фізичного виховання для розвитку просторового орієнтування в учнів початкових класів зі зниженим слухом в умовах спеціального закладу освіти. Магістерська робота складається зі вступу, трьох розділів, висновків та списку використаних джерел. У

Abstract:

H διδακτορική διατριβή μελετά ζητήματα που αφορούν την ενσωμάτωση υπολογιστικών μοντέλων ακοής για την μοντελοποίηση και επεξεργασία ηχητικών σηματών για την βέλτιστη αναπαραγωγή τους σε χώρους με αντήχηση καθώς και την κωδικοποίηση ηχητικών δεδομένων. Το κύριο μέρος της διατριβής επικεντρώθηκε στην μοντελοποίηση των αντιληπτικά σημαντικών αλλοιώσεων λόγω αντήχησης, με την βοήθεια κατάλληλα οριζόμενων μόνο-ωτικών και διαφορικών ενδο-καναλικών παραμέτρων και την απεικόνιση τους με τη βοήθεια χρονο-συχνοτικών 2Δ αναπαραστάσεων. Ο λεπτομερής εντοπισμός των αλλοιώσεων στα ηχητικά σήματα μέσω του π
