Speech Intelligibility in Noise: Perception and Prediction Models
Topic:
In noisy environments, our ability to spatially separate the voice we are trying to understand from competing sound sources can significantly improve intelligibility. This spatial unmasking is based on binaural listening, meaning we use both ears rather than the monaural signal in only one ear. Numerous models exist for predicting speech intelligibility. These models are crucial tools for evaluating and developing hearing aids and cochlear implants that restore some audibility to deaf people. They are also necessary to improve building accessibility for people with hearing impairments.
