Industrial and transport activities are the two major sources of noise pollution in any metropolitan city. Lucknow city, the capital of the largest populated state Uttar Pradesh in India has an area o...
利用互易性原理,提出了一种空气声传播路径实验方法。首先测得各声源对于车内噪声的传递函数,进而得到各声源对于车内噪声的贡献度。根据声源识别结果,对汽车车身进行吸声、隔声设计,结果表明,车内地板隔声量从前向后分别提高了1.83~9.74 dB(A),汽车车内噪声下降了4.7 dB(A)。
The problem of noise management was taken as a key element of our life comfort. An adequate noise mitigation plan must be elaborated and implemented for a number of potential noise sources. The genera...
