摘　　要：一、问题的提出 噪声对人体的危害,特别是直接对听力的危害,随着现代工业的迅速发展,已成为公害之一,越来越普遍地引起人们的极大关注。为了控制噪声和制定出可行的噪声允许标准,以期达到对人体的危害减少到最低的程度,多年来,国内外已做过不少的工作。 就人的听域而言,在一定的强度下,可听到的频率范围是很宽的。然而。The thresholds of hearing for pure tones from 125 Hz to 8000 Hz of more thantwo thousand workers after exposures for different number of years to various noiselevels were measured and their speech hearing ability under everyday life conditionswere questioned simultaneously. On the basis of these data, the thresholds of impair-ment for hearing of standard colloquial Chinese were evaluated by means of psycho-physical statistical analysis. They were 20db, 27db and 30db for three differentfrequency combinations of 500, 1000 and 2000 Hz; 1000, 2000 and 6000 Hz; and of sixfrequencies from 500 Hz to 6000 Hz respectively. In comparison with the recommendation of 25db of ISOR 1999, our result was about 5db lower.
