Circadian Regulation of Cochlear Sensitivity to Noise by Circulating Glucocorticoids

Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

The cochlea possesses a robust circadian clock machinery that regulates auditory function. How the cochlear clock is influenced by the circadian system remains unknown. Here, we show that cochlear rhythms are system driven and require local Bmal1 as well a ...

ArASL: Arabic Alphabets Sign Language Dataset

Mohammad Khaja Nazeeruddin

A fully-labelled dataset of Arabic Sign Language (ArSL) images is developed for research related to sign language recognition. The dataset will provide researcher the opportunity to investigate and develop automated systems for the deaf and hard of hearing ...

Microstructured thin-film electrode technology enables proof of concept of scalable, soft auditory brainstem implants

Nicolas Vachicouras, Florian Dylan Fallegger, Stéphanie Lacour, Christina Myra Tringides, Jennifer Mary Adrienne Alice Macron, Yohann Daniel André Thenaisie, Valentina Marie Paggi

Auditory brainstem implants (ABIs) provide sound awareness to deaf individuals who are not candidates for the cochlear implant. The ABI electrode array rests on the surface of the cochlear nucleus (CN) in the brainstem and delivers multichannel electrical ...

Fingerprinting Big Data: The Case of KNN Graph Construction

Rachid Guerraoui, Anne-Marie Kermarrec, Olivier Ruas

We propose fingerprinting, a new technique that consists in constructing compact, fast-to-compute and privacy-preserving binary representations of datasets. We illustrate the effectiveness of our approach on the emblematic big data problem of K-Nearest-Nei ...

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

Xavier Gigandet, Hervé Lissek, 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

Xavier Gigandet, Hervé Lissek, 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 ...

Experimental evaluation of speech enhancement methods in remote microphone systems for hearing aids

Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi, Ina Kodrasi

Enhancing speech intelligibility for hearing-impaired subjects in complex acoustic conditions is still a challenging topic of research. To mitigate the detrimental effects of background noise and reverberation, current hearing instruments incorporate vario ...

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 ...

Direction of Arrival with One Microphone, a few LEGOs, and Non-Negative Matrix Factorization

Ivan Dokmanic, Dalia Salem Hassan Fahmy El Badawy

Conventional approaches to sound source localization require at least two microphones. It is known, however, that people with unilateral hearing loss can also localize sounds. Monaural localization is possible thanks to the scattering by the head, though i ...

Bulged Eardrum Detection From 3D Data

Pascal Frossard, Ivana Tosic, Sofia Karygianni

Bulging is a medical characteristic of the eardrum that is crucial for the diagnosis of acute otitis media. This work proposes a novel classification method for distinguishing bulged eardrums from non-bulged ones. The method uses novel key features extract ...

The Changing Paradigm for the Surgical Treatment of Large Vestibular Schwannomas

Constantin Tuleasca

Objective Planned subtotal resection followed by Gamma Knife surgery (GKS) in patients with large vestibular schwannoma (VS) has emerged during the past decade, with the aim of a better functional outcome for facial and cochlear function. Methods We prospe ...
