从事专业音响的人经常会遇到一个棘手的问题——音响系统的噪声。长期以来这个问题让操作一人员和工程技术人员感觉非常头痛,经常是知道现象但无法分析根源,知道根源又没有合适的解决措施,加之关于音响系统噪声研究分析的文章和书籍少得可怜,所以很多技术人员只能自己琢磨,采用试探的办法来处理,常常是当时“解决了”后来又会出现,有些操作人员对实在难以处理的噪声干脆听之 Professionals engaged in professional audio often encounter a thorny problem - the sound of the sound system. For a long time, this problem has caused the operators and engineers to feel very headache. They often know the phenomenon but can not analyze the root causes, know the root causes and do not have suitable solutions. In addition, there are few articles and books about the analysis and study of sound system noise. Many technicians can only ponder on their own and adopt tentative methods to deal with them. Often, they are “solved” later, and some operators simply listen to the noise that is difficult to handle
