Conference Paper
Full-text available
In binaural sound reproduction, it has been shown that externalization improves the listening comfort. Using individualized binaural room impulse responses, it is possible to simulate sound sources in a given room for a listener wearing headphones. However, in some real-time binaural sound applications such as miniaturized hearables, it is not alwa...

The auditory system allows the estimation of the distance to sound-emitting objects using multiple spatial cues. In virtual acoustics over headphones, a prerequisite to render auditory distance impression is sound externalization, which denotes the perception of synthesized stimuli outside of the head. Prior studies have found that listeners with m...
Conference Paper
Full-text available
The auditory system enables listeners to estimate the localization of auditory events resorting notably to individual binaural cues and room reflections reaching the eardrum. For hearing-impaired listeners using hearing aids, those cues are possibly distorted or not available in various situations such as remote microphone systems. This can make au...
Conference Paper
Full-text available
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 various hardware and software strategies, among which speech enhancement algorithms are of primary...
Conference Paper
Full-text available
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 efficiency of beamformers on speech intelligibility has been demonstrated in various studies. Never...
Article
This paper presents the design and evaluation of a parametric sound texture synthesis for the generation of crowd noise in virtual acoustic environments. It allows the control of the crowd size, its level of excitement, and its spatial distribution in real-time. A corpus-based concatenative approach is used to generate single streams of indistinct...
