摘　　要：本文介绍了选择性声强技术在轿车车内噪声识别中的应用。通过对国产轿车在给定工况下的测试分析,确定出试验车发动机仓内最大噪声的位置、司机耳旁辐射噪声产生的原因,为进一步降低该车噪声提供了参考。In this paper, selective intensity technology used in in - car noise recognition of cars. By testing and analyzing on domestic car under given working conditions, the position of maximum noise in engine compartment and the reason of radiation noise generated beside the driver s ear have been ascertained. This provides the reference for further lowering the noise of the given car.
