Sound-processing strategy for cochlear implants

A sound processing method for auditory prostheses, such as cochlear implants, which is adapted to improve the perception of loudness by users, and to improve speech perception. The overall contribution of stimuli to stimulated loudness is compared with an estimate of acoustic loudness for a normally...

Beschreibung
Zusammenfassung:	A sound processing method for auditory prostheses, such as cochlear implants, which is adapted to improve the perception of loudness by users, and to improve speech perception. The overall contribution of stimuli to stimulated loudness is compared with an estimate of acoustic loudness for a normally hearing listener based on the input sound signal. A weighting is applied to the filter channels to emphasise those frequencies which are most important to speech perception for normal hearing listeners when selecting channels as a basis for stimulation.
