HEARING AID SYSTEM USING WIRELESS OPTICAL COMMUNICATIONS CAPABLE OF PREVENTING THE DEGRADATION OF THE LANGUAGE SOUND DISCERNMENT OF A SPEAKER

摘要

PURPOSE: A hearing aid system using wireless optical communications is provided to prevent the language sound discernment of a speaker from degrading regardless of surrounding noise by directly transmitting the language sound of a speaker through wireless optical communications.;CONSTITUTION: A hearing aid system comprises a hearing aid(200) inserted into the ears of a speaker and a person who has difficulty in hearing and a language sound transmitter(100) inserted into the ears of the speaker. The language sound transmitter changes a language sound into an optical signal. The hearing aid restores the optical signal received from the language sound transmitter into the language sound of the speaker. The language sound transmitter includes a first microphone and a second microphone which change the language sound of the speaker into a voice signal. A signal processing unit amplifies one of the voice signal applied in the first microphone and the voice signal applied in the second microphone. A lighting emitting unit changes the signal amplified in the signal processing unit into the optical signal.;COPYRIGHT KIPO 2012
