在前额、前胸和前腹部测量低频噪声引起的体表振动（噪声引起的振动）。在所有测量位置，噪声引起的振动的振动加速度水平的增加步长与噪声刺激的声压水平的增加步长非常一致。发现在前额测量的振动加速度水平在 31.5-40 Hz 左右突然增加，而在胸部和腹部测量的加速度水平在 20-50 Hz 范围内以近似恒定的速率随频率增加。我们的结果表明，没有明确的证据表明姿势或双边不对称对噪声引起的振动有影响。我们发现，在胸部和腹部测量的噪音引起的振动与身体脂肪百分比呈负相关。
The body surface vibration induced by low frequency noise (noise-induced vibration) was measured at the forehead, the anterior chest and the anterior abdomen. At all the measuring locations, the increase steps in the vibration acceleration levels of the noise-induced vibrations was in good agreement with the increase steps, in the sound pressure levels of the noise stimuli. The vibration acceleration level measured at the forehead was found to increase suddenly at around 31.5–40 Hz, while the acceleration levels measured at the chest and abdomen increased with frequency at approximately constant rates in the 20- to 50Hz range. Our results showed no clear evidence of the effect of posture or bilateral asymmetry in the noise-induced vibration. We found that the noise-induced vibrations measured at the chest and abdomen were correlated negatively with the body fat percentage.
