Human ultrasonic speech perception

ML Lenhardt, R Skellett, P Wang, and AM Clarke

Department of Otolaryngology, Medical College of Virginia, Virginia Commonwealth University, Richmond 23298.

Bone-conducted ultrasonic hearing has been found capable of supporting frequency discrimination and speech detection in normal, older hearing-impaired, and profoundly deaf human subjects. When speech signals were modulated into the ultrasonic range, listening to words resulted in the clear perception of the speech stimuli and not a sense of high-frequency vibration. These data suggest that ultrasonic bone conduction hearing has potential as an alternative communication channel in the rehabilitation of hearing disorders.
