Intérêt de la prise en compte de propriétés auditives en annulation d'écho et débruitage

摘要: Communication with an audio terminal device that operates in hands-free mode may be seriously impaired by the acoustic echo and ambiant noise. Thus cancellation noise reduction techniques are required to guarantee good qua lity of communication. In place classical approaches, we propose a method reduce these perturbations based on optimal filtering. The introduction psychoacoustic criteria - which rely hybrid masking model filtering technique enables amount distortion generated filter. Results simulations show use human auditory properties our yields effective when perturbation is speech.
