Time-frequency speech processing strategy based on an adjustable algorithms dedicated to the cochlear prostheses

Abstract

Cochlear implants are electronic devices designed to provide useful hearing and improved communication ability to individuals who are profoundly hearing impaired and unable to achieve speech understanding with hearing aids. For individuals with a profound hearing loss, even the most powerful hearing aids may provide little to not benefit. A profoundly deaf ear is typically one which the majority of sensory receptors in the inner ear, called hair cells, are damaged or diminished. Cochlear implants bypass damaged hair cells and directly stimulate the residual hearing nerves with electrical current, allowing individuals who are profoundly or totally deaf to receive sound.
