为了弄清人体对空气振动的机械反应，6名男性受试者被暴露在8种低频噪声刺激下：空气中的白噪声，2种纯音(31.5和50赫兹)，以及5种由纯音组成的复合噪声。在前额、右前胸和左前胸、右前腹和左前腹五个位置测量了体表诱发的振动。结果发现，胸部振动中31.5和50赫兹分量的振动加速度水平与噪声刺激中各相应频率分量的声压水平近似线性增加。胸部振动中的31.5和50赫兹分量之间没有明显的干扰。在前额和腹部诱发的振动中也发现了类似的特征。这些发现表明，在这里使用的有限的频率和声压级范围内，人体作为一个机械线性系统来响应复杂的低频噪声引起的空气中的振动。
To clarify the mechanical responses of the human body to airborne vibrations, six male subjects were exposed to eight kinds of low-frequency noise stimuli: airborne white noise, two pure tones (31.5 and 50 Hz), and five complex noises composed of pure tones. The vibrations induced on the body surface were measured at five locations: the forehead, the right and left anterior chest, and the right and left anterior abdomen. It was found that the vibration acceleration levels of both the 31.5- and 50-Hz components in the chest vibration increased as an approximately linear function of the sound pressure levels of each corresponding frequency component in the noise stimulus. No clear interference was found between the 31.5- and 50-Hz components in the chest vibration. Similar characteristics were also found in the vibrations induced at the forehead and abdomen. These findings suggest that within the limited range of frequency and sound pressure level used here, the human body acts as a mechanically linear system in response to airborne vibrations induced by complex low-frequency noise.
