The invention provides an electronic cochlear signal processing and electrical stimulation coding system and a processing method thereof. The system includes: an acoustic signal analysis and processing module, an electrical stimulation discrimination test and processing module, and an electrical stimulation coding module. The acoustic signal analysis and processing module analyzes the acoustic signal and extracts the characteristic information that needs to be transmitted in the low-frequency and high-frequency channels. The electrical stimulation discrimination test and processing module measures and fits the electrical stimulation site discrimination ability and electrical stimulation rate discrimination ability of individual cochlear electronic users, and calculates and processes parameters for individual cochlear electronic users to distinguish and perceive electrical stimulation modes. The electrical stimulation coding module jointly determines the discharge mode of the cochlear implant electrode according to the individual cochlear user's ability to receive electrical stimulation information and the acoustic signal processing results. The system of the invention can maximize the listening ability of the electronic cochlear users, and improve their ability to recognize speech under noise background, understand tone language and music.
Description
technical field [0001] The invention relates to the field of cochlear electronics, in particular to a cochlear electronic signal processing and electrical stimulation encoding system and processing method thereof, which are suitable for improving the ability of the electronic cochlear to recognize speech in a noise background, understand tone language and music. Background technique [0002] Cochlear implant technology is currently the only neuroprosthetic that can restore hearing to the deaf. By directly stimulating the auditory nerve with electric current, the deaf can restore their hearing. It has helped more than 120,000 cochlear implant recipients around the world restore their hearing to varying degrees. Currently the most widely used cochlear electronic signal processing strategies, such as: continuous alternate use scheme CIS (continuous-interleaved-sampling), advanced mixed coding scheme ACE (advanced confined encoding) all generate electrical stimulation pulses with...
