The development of speech coding strategies for cochlear implants;

Objective To introduce the wavelet zero -cross stimulation algorithm and based on which to design and implement the cochlear implants.

Cochlear implants(CI) are medical devices that can restore partial hearing to a profoundly or totally deafened person via exciting the residual heating neurons directly in accordance with the principle of functional electrical stimulation.

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;

Cochlear implant(CI) is a neural prosthetic device used to provide the sensation of sound to those who are profoundly deaf by delivering electrical stimulus to auditory nerve directly.
