Résumé

An experimental approach to identify the optimal reverberation time in an idealized room, and validate theoretical prediction was discussed. Subject groups for the study were normal-hearing and hard-of-hearing people with a mild to moderate sensori-neutral hearing loss. Hard-of-hearing people needed high signal-to-noise level difference rather than shorter reverberation time to achieve better speech intelligibility. The results show that the optimal reverberation times depends on the signal-to-noise level difference and the spatial relationship between the listener and the sound sources for both normal and hard-of-hearing subjects.
