By using complex low-frequency noise, which were made of two pure tones within the 16-80 Hz range, as test stimuli, we measured the threshold levels and the equal-sensation levels for "vibration perceived in the head", and compared them to those levels for hearing sensation. The hearing sensation was found to be contributed dominantly by a tonal component at a higher frequency, while the perception of vibration in the head was found to be contributed by both tonal components. This result suggests that vibratory sensation is more easily induced by complex low-frequency noise containing plural frequency components whose sound pressure levels are close to the threshold levels for inducing vibratory sensation. It is reasonably deduced that the effect of vibratory sensation needs to be taken into account in assessing psychological effects of such complex low-frequency noise.

通过使用复杂的低频噪声，这是由两个纯音在16-80 Hz的范围内，作为测试刺激，我们测量的阈值水平和等感觉水平的“振动感知在头部”，并比较它们的听觉水平。听觉被发现主要由较高频率的音调分量贡献，而头部振动的感知被发现由两个音调分量贡献。该结果表明，振动感更容易由包含多个频率分量的复合低频噪声引起，所述多个频率分量的声压级接近用于引起振动感的阈值级。合理地推断，在评估这种复杂的低频噪声的心理影响时，需要考虑振动感觉的影响。
