Auditory externalization of a remote microphone signal

Vincent Pierre Olivier Grimaldi

A remote microphone (RM) system can be used in combination with wearable binaural communication devices, such as hearing aids (HAs), to improve speech intelligibility. Typically, a speaker is equipped with a body-worn microphone which enables to pick up th ...

Design and modelling of a compliant constant-force surgical tool for objective assessment of ossicular chain mobility

Simon Nessim Henein, Charles Baur, Loïc Benoît Tissot-Daguette

Surgeons generally assess the mobility of the ossicle chain by manual palpation using rigid elongated hooks inserted through the ear canal. As the applied forces are in the range of a few grams equivalent force, the measurement remains subjective and its r ...

Inner ear imaging is important for the assessment of hearing disorders. A major cause of hearing loss is the damage to the sensory hair cells, which are located inside the cochlea, a spiral-shaped bone in the inner ear. Imaging of intracochear hair cells i ...

Auditory externalization in hearing-impaired listeners with remote microphone systems for hearing aids

Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi

The auditory system enables listeners to estimate the localization of auditory events resorting notablyto individual binaural cues and room reflections reaching the eardrum. For hearing-impaired listenersusing hearing aids, those cues are possibly distorte ...

Subjective evaluation of a spatialization feature for hearing aids by normal-hearing and hearing-impaired subjects

Hervé Lissek, Xavier Gigandet, Gilles André Courtois

Remote microphone systems significantly improve speech intelligibly performance offered by hearing aids. The voice of the speaker(s) is captured close to the mouth by a microphone, then wirelessly sent to the hearing aids. However, the sound is rendered in ...

Effects of Binaural Spatialization in Wireless Microphone Systems for Hearing Aids on Normal-Hearing and Hearing-Impaired Listeners

Hervé Lissek, Xavier Gigandet, Gilles André Courtois

Little is known about the perception of artificial spatial hearing by hearing-impaired subjects. The purpose of this study was to investigate how listeners with hearing disorders perceived the effect of a spatialization feature designed for wireless microp ...

Objective evaluation of static beamforming on the quality of speech in noise

Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi

Beamforming is commonly used in devices such as in hearing instruments (HI) with a view to reducing noise. It consists in focusing on audio signals arising from a prescribed steering direction while suppressing those coming from other directions. The effic ...
