Body surface vibrations were measured at the right and left anterior chest and the right and left anterior abdomen of male subjects. Subjective unpleasantness was rated on a scale of 1 to 5, and correlated with the vibration acceleration levels (VALs) of the vibrations measured on the body surface. As a result, it was found that the ratings of unpleasantness did, on the whole, significantly correlate with the VALs. In addition, we estimated the frequency-weightings for the VAL to optimize the correlation with the rating of unpleasantness. Based on a reasonable hypothesis, the frequency-weightings estimated in the present study were considered to be consistent with those estimated in our previous study using low-frequency pure tones. The present results support the idea that not only the loudness of a noise, but also the vibrations induced by that noise, contribute to the subjective unpleasantness experienced by persons exposed to high-level low-frequency noise. The effect of vibration should be taken into consideration in evaluating high-level low-frequency noise.
