Research Highlight: Understanding how acoustic information is processed
ENP team leader and Collège de France professor Christine Petit has made major advances in our understanding of how the peripheral auditory system processes acoustic information. She recently published a review article on auditory distortions. This article discusses the mechanisms underlying the non-linear amplification of vibrations induced by weak sounds in the cochlea. This non-linear amplication generates instantaneous waveform distortion, which has consequences on the processing of the original auditory stimuli.
