Auditory stimulation using CW and pulsed signals

摘要

An improvement in noise susceptibility is realized in auditory stimulation of the deaf by electrical signals. At least one analog electrical signal is applied to implanted electrodes in a patient, and at least one pulsatile signal is applied to implanted electrodes. The analog signal represents a speech signal, and the pulsatile signal provides specific speech features such as formant frequency and pitch frequency.
