【摘要】 本文论述了某厂无振动作业的433名健康工人振动觉、痛触觉测定的方法及结果。据测定结果,我们建议选用62.5Hz、125Hz频率进行左手第Ⅱ、Ⅲ指的振动觉阈值测定。我们认为正常人振动觉阈值的95%上限:男性为17.5dB,女性为15dB。更多还原

【Abstract】 Vibratory and pain sensation thresholds for 433 healthy workers without history of vibration exposure in one factory were studied. The results suggested that for the measure ment of the vibratory thresholds at the 2nd and 3rd fingers of left hand, 62.5Hz and 125 Hz would be the frequencies of choice. It was also recommended that the upper limit (95 percent) of normal human vibratory thresholds would be: male 17.5dB, female 15dB.更多还原
