Position

Researcher for the Ministry of Ecology, Sustainable Development and Energy

Research topics

My research aims at understanding and predicting how sound perception and (auditory) comfort are influenced by the surrounding environment, in particular room reverberation (the multiple sound reflections on room boundaries), which is mixed with the direct sound from the sources, and modifies the signal at the listener’s ears. My goal is to study the perceptual effects associated with these modifications, and to propose relevant acoustical measurements to describe them. I consider sound perception in terms of speech intelligibility in noise and source localization. I am also interested in sound reproduction in rooms, and I am beginning to investigate the influence of the sound environment on inhabitants’ comfort.

I am considering the auditory system as a measurement tool allowing an evaluation of intelligibility and sound quality - by quality I mean “characteristics” rather than “good” or “bad” - and as a subject of study, in order to understand the complex processing involved while we are listening. My goal is to define acoustical measurements relevant for the improvement of auditory comfort in ordinary rooms, not only in big music halls and amphitheaters. My research can also be applied to vehicles and partially closed spaces (stations, streets …), and to the improvement of hearing-aids.
