Vibrations from the Shinkansen, an express which runs at 100-200kph and which creates 74-86dB were measured on the head of one subject in the residential house by a method using tooth impression, in order to determine its applicability as a method of measuring environmental vibration in field conditions. In doing so, transmission of vibrations to the human head could be examined.The results were as follows;1. From 16 to 63Hz, there was a high correlation in vibration acceleration level between the tooth impression and the tatami mat, suggesting that the responses of the head to vibrations are linear between 45dB and 75dB.2. The vibration response curve was similar to those previously obtained on different days in different locations using identical methods, confirming the reliability of tooth impression method as a field measure.3. When the body is supine, vibration acceleration level of train on the tatami mat increased in the frequency range 31.5-63Hz on human head for the forward-back direction (X).
