Study on the Four-channel Skin-hearing Aid Based on Morse Codes

To enhance the identification capacity of the skin-hearing aid for voice signals, the four-channel skin-hearing aid based on Morse encoding method is proposed in this article, which can overcome many disadvantages such as low identification rate and bad anti-jamming capability existing in analog variable pressure skin-hearing aid. By processing voices, seeking the corresponding Morse code of voice signals, establishing the skin response voltage sequence by the Morse encoding, stimulating the skins by this voltage sequence, and making the skins to more clearly feel different signals of voice, the identification rate of skin hearing can be enhanced obviously.
