An evaluation system for testing the performance of cochlear implant speech strategies

Abstract

The invention relates to a performance evaluation system for testing the language strategy of an electronic cochlea. The system comprises a sound source module used for providing true sound signals for an electronic cochlea device with the loaded language strategy to be evaluated and a standard audio input module, the standard audio input module used for converting the sound signals provided by the sound source module into standard audio signals, a signal collecting module used for collecting electric signals output by the electronic cochlea device and electric signals output by the standard audio input device, an audio processing module used for converting the collected audio signals of standard sounds into sound spectrum signals and standard simulation electrode signals and transmitting the two converted kinds of signals to a strategy result comparison display module, and the strategy result comparison display module which is used for comparing the sound spectrum signals and the standard simulation electrode signals with the audio signals of the electronic cochlea device and determining whether the language strategy meets the requirements or not.

Description

technical field [0001] The invention relates to the field of engineering detection, and proposes a performance evaluation for cochlear electronic speech strategy, which is used for the quality evaluation of electronic cochlear hardware equipment and the research of electronic cochlear speech strategy. Background technique [0002] A cochlear implant is a medical device that converts sound signals into electrical signals and needs to be implanted into the brain of deaf patients to replace the function of the cochlea. Since the device is essentially a sound-to-electricity conversion device that discharges directly to the human brain, the duration of the cochlear discharge to the brain, the magnitude of the current, and the amount of charge must be strictly controlled within a safe range. The above parameters directly reflect the electrode performance of the cochlear implant as well as the stability and reliability of the current source and the crystal oscillator. At present, ...
