Abstract : This paper describes the development of a transdermal hearing system using modulated electrical carrier signals to stimulate sound perception. Current version of this system uses amplitudemodulated alternating-current carrier signals capacitively coupled to the skin of the head and neck. The transdermal system has been shown to produce undistorted sound perception in normal humans and improvement in those with impaired hearing. It has also been shown to elicit rudimentary signal discrimination in totally deaf humans. The transdermal stimulation of audition has been extended to dogs made deaf by cochlear destruction as evidenced by positive conditioned reflex experiments. (Author)
