Abstract

種々の音の聴取がヒトの感性に影響を及ぼすことが知られているが, その客観的評価については未だ決定的なものはえられてない.我々は, ヒトに8種類の音楽と白色雑音および正弦波を呈示し, この際の官能検査結果と脳波および脈波の変化との関連づけを行った.その結果, 不快な音を聴取した際は脳波β波成分が増大した.一方, 快い音や澄んだ音を聴取した際は脳波α波成分およびθ波成分が増大し, 脈波から得られた副交感神経成分が増大した.

we examined changes of electroencepharograms(EEGs) and pulse waves in subjects while eight kinds of musics, a white noise and a sine wave were applied to them. At the same time, we also examined psychological effects of subjects for these sounds to investigate the relationship between biological signals and psychological features. power spectrum component of β wave in EEGs increased in listening of unpleasure sounds. While, power spectrum components of α and θ waves and parasympathetic component in pulse waves increased in listening pleasure and clear sounds.
