• Development and Effect of A Hi-Definition Induction Loop System.

抄録

It is well known that a frequency response via induction coil of a hearing aid is different from a frequency response via microphone (low tone part is especially reduced). Because of this phenomenon, meny hearing aid users dislike “via inductive coil sound”.<br>Auther developed a hi-definition induction loop system to obtain a frequency response via microphone. Further, an improved telephone and a small sized induction loop system (apprication systems) is tested by hearing aid (equipped with an inductive coil) users (average 80-105dB HL).<br>The results obtained were as follows;<br>1) A hi-definition loop system was used effectively for all kinds of hearing aid (equipped with an inductive coil) users.<br>2) It was proved that “via inductive coil sound” became comfortable and clear by using a hi-definition induction loop system.<br>3) For more comfortable listening, a hi-definition induction loop system with a trimmer in a magnetic field is very effective.
