Audiological research at Ecole normale superieure, Paris, France
Short_talk Audiological research at Ecole normale superieure, Paris, France Christian Lorenzi Ecole normale superieure & CNRS 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).
