Research Abstract

In this study, we aim to develop the smart hearing aid for selective listening by using brain signals such as MEG and EEG. For this purpose, we investigated the neural mechanism of the selective listening with the coherence function between a sound envelope and MEG signals. As some of obtained knowledge, we found that the coherence values of the noticed sound became higher than the unnoticed sound and the voice sound showed comparatively high conference values in the left hemisphere regardless of the sound source direction. For practical use, we tested the possibility of wearable EEG devices.
