摘　　要：通过驻极体麦克风组成的麦克风阵列对汽车发动机舱进行噪声的采集,将阵列中各个采集节点的噪声值在摄像头视野内的物理位置对应,并将各节点噪声值实时标识出来,可以使用户方便的观测噪声不符合设计要求的位置,方便进行下一步改进。The noise of the car engine compartment is collected through an array composed of electret microphones,and the noise value of each collection node in the array is corresponding to the real position of the camera field of view,and the noise value of each node is identified in real time,which allows users to observe conveniently the location where the noise does not meet the design requirements is convenient for the next improvement.
