Abstract

We examined changes of electroencepharograms (EEGs) and pulse waves while subjects lissten to different type of sound, a white noise and a sine wave. At the same time, we also examined subjective estimations for each sound using a method of sensory inspection, and investigated the relationship between these sounds and subjective estimations. As a result, the power spectrum component of β (P<0.01) wave in EEGs(Fz) increased in listening of unpleasure sounds. While, power spectrum components of α (P<0.01) and θ (P<0.01) waves increased in listening pleasure sounds.
