生用ヘツドホン２７へ供給する受信部２５と からなることを特徴とする補聴装置。[Claims for Utility Model Registration] An input section 21 connected to an acoustic signal output terminal of a television receiver 20, radio receiver, etc., and a carrier wave that is frequency-modulated by the signal from the input section 21 and sent into the air. A first transmitting section 22 frequency-modulates a carrier wave having the same frequency as that of the first transmitting section 22 using the acoustic signal collected by the microphone 30, and the output level thereof is modulated by the first transmitting section 22. A second transmitter that sends out into the air is set to be stronger than the radio waves emitted from the second transmitter, and when radio waves are sent out simultaneously from each transmitter, the stronger one emitted from the second transmitter due to the capture effect 1. A hearing aid device comprising a receiving section 25 that receives and demodulates only the radio waves of the hearing aid, and supplies the output to a reproduction headphone 27.
