The combined effects of vibration and noise on palmar sweating were studied experimentally in healthy subjects. Ten subjects were exposed to vibration at an acceleration of 100 m.sec-2 root mean square at a frequency of 125 Hz, a noise level of 105 dB(A) at a frequency of 1000 Hz and both stimuli together. Vibration was applied to the right hand and noise to both ears from headphones. Palmar sweating was measured by the ventilated capsule method. Vibration caused a marked increase in palmar sweating of the right hand directly exposed to vibration and also of the left hand not exposed to vibration. Simultaneous vibration and noise caused a greater increase in palmar sweating than by each of the factors separately. The combined effects tended to be greater in subjects who were more susceptible to vibration or noise.
在健康受试者中对振动和噪声对手掌出汗的综合影响进行了实验研究。10名受试者分别暴露于均方根加速度为100 m·sec⁻²、频率为125 Hz的振动，1000 Hz频率下105 dB(A)的噪声水平以及两种刺激同时作用的环境中。振动施加于右手，通过头戴式耳机向双耳施加噪声。采用通气胶囊法测量手掌出汗情况。振动导致直接暴露于振动的右手以及未暴露于振动的左手的手掌出汗显著增加。同时施加振动和噪声比单独施加每种因素时导致手掌出汗增加得更多。在对振动或噪声更敏感的受试者中，综合影响往往更大。
