HEARING-AID APPARATUS AND METHOD USING ULTRASONIC WAVES |
| 摘要 |
A hearing-aid apparatus using ultrasonic waves is inserted and mounted within an external auditory meatus of an ear, generates an ultrasonic wave band signal by single side band amplitude modulation of a sound signal that is received through a microphone, and outputs the ultrasonic wave band signal and a carrier signal that is used for single side band amplitude modulation as an ultrasonic wave signal to a transfer medium in a predetermined beam direction. Therefore, the ultrasonic wave signal forms a focal area in a damaged hearing organ area, the ultrasonic wave band signal is restored to a sound signal by nonlinear characteristics of a transfer medium in the focal area, and the damaged hearing organ detects the sound signal. |

1. A hearing-aid apparatus using ultrasonic waves, comprising:
a microphone that receives a sound signal; a signal processor that generates an ultrasonic wave band signal by single side band amplitude modulation of the sound signal; and an ultrasonic wave element array comprising a plurality of ultrasonic wave elements and that outputs an ultrasonic wave band signal and a carrier signal that is used for single side band amplitude modulation as an ultrasonic wave signal in a predetermined beam direction to a transfer medium, wherein the hearing-aid apparatus is inserted and mounted within an external auditory meatus of an ear. |
