二、环境噪声的测量 关于环境噪声、交通噪声具体的测量方法,国务院环办已颁布了标准方法(试行)。声级计的使用也可参阅具体的使用说明书。在这一节我们将着重介绍噪声测量中总要遇到的A声级是什么含义,噪声测量结果为什么要用统计值和等效值表示,如何从测量数据得到这些统计值和等效值。 (一)A声级 我们知道噪声的接受体是人的听觉器官——人耳,而人耳对声级的响应,并不呈简单 Second, the measurement of environmental noise About environmental noise, traffic noise measurement methods, the State Council Central Office has enacted a standard method (for trial implementation). The use of sound level meter can also refer to the specific instruction manual. In this section we will focus on what the mean A level of the noise measurement is to be, why the noise measurements are expressed in statistics and their equivalents, and how these statistics and their equivalents are derived from the measured data. (A) A sound level We know that the receiver of noise is the human auditory organ - human ear, and the human ear response to the sound level, is not simple
