The human ear: a living sensor

This lecture explores the fascinating sensor capabilities of the human ear, focusing on the non-linear phenomena within the cochlea responsible for sound conversion. The presentation delves into the experimental reproduction of cochlear response using resonant tubes and the creation of an 'animated' metamaterial mimicking the living character of the cochlea. Fabrice Lemoult, an Associate Professor at Institut Langevin, discusses the transposition of acoustic metamaterial results to the field of hearing, shedding light on the potential to enhance microphone performance.
