According to the structural property of actual meatus auditorius,We develop an objective method of artifical meatus auditorius to measure sound insulation performance of earplug.

CIS algorithm of cochlear implants′ speech signal processing is achieved through hardware method.

Through stimulating remainder hearing nerve by electrical signal, cochlear implants are the only medical tools that can make the deaf get part audition.

Methods One hundred and twelve patients with LVAS who received cochlear implants between the year of 2000 and 2008 at the Cochlear Implant Center of Beijing Tongren Hospital were investigated in this study.

An observation and application of the electrode impedances and electrically-evoked compound action potentials after cochlear implantation using two types of electrodes;

[Objective] To observe the change of the electrode impedances and the thresholds of the electrically-evoked compound action potentials in different time points after cochlear implantation and to help for deciding the interval of the mapping.

Objective To investigate the related issues of cochlear implantation procedure.

The improvement of the cochlear implantation CIS speech processing method based on the all phase DFT filter;

An approach to the speech rehabilitation of children at the age of 2 to 5 years after cochlear implantation;

A research on influential factors of language rehabilitation of prelingually deafened children with multichannel cochlear implant;

The Study on Speech Signal Processing of Cochlear Implant Based on DSP;

This paper introduces the working principle of cochlear implants, and its continuous interleave sampling (ClS)speech signal processing method, presents the design of the electronic circuit and the flow chart of software programming.
