Abstract
Ultrasounds are perceived through bone-conduction by profoundly deaf as well as normal hearing subjects. A bone-conducted ultrasonic hearing aid (BCUHA) was developed for the profoundly deaf. Parameters of BCUHA were determined by former psychoacoustic and neuromagnetic experiments. Using BCUHA 53% of the profoundly deaf subjects were able to perceive sounds, and 18% of them were able to recognize some words.
