Our team is conducting research on the perceptual consequences of aging and cochlear
damage.
This team (http://www.iec-lsp.ens.fr/) is part of the Laboratoire des systemes perceptifs
(LSP, IEC, ENS), a CNRS research unit of the Departement d'Etudes Cognitives (DEC, IEC)
at Ecole normale superieure, in Paris, France.
We combine psychophysical, neurophysiological and modelling methods to investigate
the perception of temporal modulations in sounds by the normal and impaired auditory
system.
We currently conduct cross-linguistic studies to characterize temporal-modulation
information (amplitude modulation, AM, and frequency modulation, FM) in speech.
We explore the neural coding of AM and FM information at the early stages of the
auditory system and the central effects of aging and cochlear damage on AM and FM
processing.This is achieved by recording neural responses to AM and FM in the low
brainstem and auditory cortex of guinea pigs (collaboration: Univ Cambridge, UK; Univ
Orsay, France), and by investigating interference and integration effects for AM and FM
detection in normal-hearing and hearing-impaired humans (collaboration: Univ
Cambridge, UK).
We also investigate the auditory development of modulation perception during infancy
and childhood (collaboration: UCL, UK). A computational model of AM and FM
processing using temporal-envelope and temporal fine-structure information is under
development (collaboration: Hearing4all, Germany, Oldenburg).
