Abstract
Binaural hearing aids with a voice transmitter have been widely used to enhance sound quality in noisy environment. However, this system has a limitation on sound-source localization. In this study, we investigated automatic directional-gain control method using geomagnetic sensors to provide directional information to binaural hearing aid user. The loudness gains of two hearing aids were differently controlled based on the directional information between a speaker position and a viewing direction of hearing aids user. This relative directional information was measured by two geomagnetic sensors on hearing aids user and a speaker. The results showed that the loudness gains were accurately controlled and could provide directional information based on the cue of interaural level differences.
