Abstract

A speech processor for artificial cochlea is composed of a speech amplifier module for amplifying and filtering the speech signals coming from microphone, a digital signal processing module with DSP chip for A/D conversion, time-frequency analysis and digital encoding, an RF transmitter module, display control module, and power supply module.

Description

technical field [0001] The invention relates to a cochlear implant, in particular to a speech processor of the cochlear implant. Background technique [0002] The human ear can be divided into three parts: the outer ear, the middle ear and the inner ear. The main function of the outer ear and the middle ear is to conduct the external sound to the inner ear through the tympanic membrane and the three auditory ossicles connected to it. The inner ear is about the size of a soybean, shaped like a snail shell, also known as the cochlea. There are tens of thousands of auditory sensory cells in the cochlea—hair cells, which convert the acoustic energy (mechanical energy) from the middle ear into electrochemical energy to cause the excitation of the auditory nerve, which transmits the sound information to the cerebral cortex in the form of electricity And produce hearing. Deafness caused by inner ear hair cell lesions is sensorineural deafness, and there is currently no effective...
