CHANNEL-SPECIFIC LOUDNESS MAPPING FOR PROSTHETIC HEARING SYSTEMS

摘要

Generating electrode stimulation signals is described for stimulating cochlear tissue using an implanted electrode array. An acoustic audio signal is processed to generate band pass signals which represent an associated band of audio frequencies. Stimulation information is extracted from the band pass signals to generate stimulation event signals that define electrode stimulation signals. The stimulation event signals are then weighted according independent channel-specific loudness functions to produce electrode stimulation signals. The electrode stimulation signals are developed into output electrode pulses to the electrodes in the implanted electrode array for stimulating cochlear tissue.
