Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenhardt, M L -- Skellett, R -- Wang, P -- Clarke, A M -- New York, N.Y. -- Science. 1991 Jul 5;253(5015):82-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Otolaryngology, Medical College of Virginia, Virginia Commonwealth University, Richmond 23298.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2063208" target="_blank"〉PubMed〈/a〉
