摘    要:对13种制造工业的200家工厂工业噪声源进行了测量,测量结果表明,工业设备噪声级dBA的分布是一个正态分布,具有分布函数P(L_A)=1/(2π)~(1/2)σexp〔-(L_A-L_(50))~2/2σ~2〕.若A声级的概率分布是理想的高斯分布,则从噪声级的正态分布曲线上所得到的L_(10)、L_(15)、L_(50)、L_(84)和L_(90)声级,可以用来计算Leq和σ.实验可得出常用工业设备产生的噪声级的范围及其统计特性.

Abstract:Like traffic noise, noise from industrial equipments affects the neighborhoods around the plant. Measurements on noise of the most common industrial sources have been made. The results are based primarily on measurements out of 200 plants selected from thirteen manufacturing industrial categories. Data show that distribution of noise levels in dBA for industrial equipments is in the form of normal distribution, with a probability functionIf the probability distribution of the A level is reasonably of a Gaussian curve.
