HEARING AID SYSTEM USING WIRELESS OPTICAL COMMUNICATIONS

---

Abstract

---

Provided is a hearing aid system using a wireless optical communications method. The hearing aid system includes: a voice transmitter that converts addresser's voice into an optical signal to then transmit the converted optical signal; and a hearing aid that restores the optical signal received from the voice transmitter into the addresser's voice to then output the restored addresser's voice. Accordingly, the addresser's voice can directly be transmitted to the hard-of-hearing via wireless optical communications, to thereby prevent a voice discriminating power from lowering even in the case that ambient noise of an addresser as well as a listener is big.
