许多企业对强度较高的噪声源进行治理,以图控制噪声危害,保护工人健康。但调查中发现,企业由于缺乏治理参数和专业技术,虽投入了大量的人财物力,但效果不佳,其原因分析如下: 一、空气动力性噪声其治理方法主要采用消声器,将声能通过摩擦或粘滞效应转变成热能消耗掉。但发现有的声源使用消 Many enterprises control the high-intensity noise sources in order to control noise hazards and protect workers’ health. However, the survey found that due to the lack of governance parameters and professional and technical enterprises, although a lot of financial resources and financial resources have been invested, but the results are not good. The reasons are as follows: First, the aerodynamic noise control method mainly uses mufflers to transmit sound energy Friction or sticking effect is converted into heat energy consumed. But found that some of the sound source to use consumer
