摘要： The present invention provides an electrical stimulation method and apparatus to stimulate nerve fibers, turning on suitable combination of adjacent electrodes simultaneously to form virtual channels based on predetermined rules, so that the stimulation signal will generate or evoke a nerve response spectrum that matches the original signal spectrum presented as the input sound. The method includes the steps of receiving a sound signal by a receiving unit; dividing the received sound signal into a plurality of frequency bands by a processing unit; extracting a spectral peak from each of the frequency bands and determining a stimulation sequence of frequency bands by the processing unit; and selectively driving a plurality of electrode groups in a plurality of cycles based on the stimulation sequence of frequency bands and a determination rule by the processing unit, so that the nerve response that matches the original signal will be generated.

摘要： This present invention discloses an audio-separating apparatus and operation method thereof. The audio-separating apparatus applies both blind source separation and noise reduction mechanisms. The audio-separating apparatus only uses one microphone to record mixed sound signals. After applying the noise reduction mechanism, noise reduced signals and the mixed sound signals are used as the inputs of the blind source separation. The method may avoid the spatial aliasing effect caused by using a microphone array to record the mixed sound signals. Besides, speech segment losses caused by processing the noise reduction will be effectively recovered, which may help the hearing impaired recognize target speech signals.
