摘要
本文分析了管道有源噪声控制中需要解决的关键问题 - -次源声反馈及系统非理想响应 ,从传递函数的角度分析了由于二者的存在单纯的延时环节和反相环节难以取得理想降噪效果的原因 。
The essay analyzes the key problems of feedback of the second source noise and non-ideal response of the system, which can be solved in the activenoise control in ducts. The article puts forward the two causes, which areresponsible for the ineffective noise reduction at the single time-lapse or theanti-phase and hence offers keys to the headaches.\;
