ÉTude de la pERception soNorE de Personnes maLentendantes équipées d'Aides Auditives
The aim of the ETERNEL project will be to study the influence of the perception of a single sound timbre on the understanding of a complex sound scene in hearing-impaired people with hearing aids. This will be done by quantifying the inability to manage a complex sound scene as a function of the timbre of the sounds making it up. The more a sound interferes with understanding the complex sound scene, the more salient that sound is considered to be. In this way, the investigators can determine which timbre dimensions make sounds particularly salient for the hearing impaired.
