SOUND ENHANCEMENT FOR COCHLEAR IMPLANTS

摘要

This document mainly discloses a method and a device for sound enhancement, both aspects of the invention hereby described are directed to cochlear implants. The method for sound enhancement and the sound enhancement device comprising a component adapted to carry out said method are based on processing the envelope for frequency bands of the acoustic signal captured, said amplification is directed to the gain value of the amplification according to an amplitude of an output signal of the other sound processor.

1. Sound enhancement method for cochlear implant sound processors, the method comprising:
capturing at least an acoustic signal by means of a microphone of one of two interconnected sound processors, breaking down the acoustic signal into frequency bands, by means of the sound processor capturing the acoustic signal, respectively extracting for each frequency band an envelope, by means of the sound processor capturing the acoustic signal, the method characterised by comprising: amplifying the envelope, by means of the sound processor capturing the acoustic signal, said amplification comprising in turn modifying a gain value of the amplification according to an amplitude of an output signal of the other sound processor, wherein the relationship between the gain and the amplitude is that of the higher the energy of the amplitude of the output signal the lower the gain of the amplification and vice versa.
