Abstract :
Receptor (hair cell) loss in the inner ear (cochlea) causes nerve deafness. Surgical treatment with artificial ears (cochlear implants) recreates certain properties of normal hearing. The essential concept behind the Purdue Artificial Receptor (PAR) invention is that it recreates the normal signal processing of auditory receptors. Controlled experiments have demonstrated that PAR processing improved speech perception in every nerve-deaf patient studied. PAR is currently implemented in hardware as a single-channel, battery-powered, portable, real-time digital-signal-processor based computer which simulates natural receptor function. Future multichannel PARs will add spectral information to improve pitch perception
