| Research Abstract |
It was found that there was the effect of high frequency components in dental noise on subjective impression using Near Infra-Red Spectroscopy(NIRS). And the activation of the cerebral prefrontal area at the time of the consciousness of high frequency components was shown clearly. Furthermore, we succeeded in development of measurement system for air-conducted and bone-conducted sound and in measurement of the bone-conducted wave at the time of drilling a tooth.
