Application of Acoustic Reciprocity in Noise Path Analysis
並列摘要
Vehicle interior noise is a major issue in vehicle NVH problems for years. The ideal noise paths analysis method is not only to track the noise paths but also to quantify the contributions from each structureborne and airborne noise source. This paper demonstrates the capability of identifying structureborne and airborne contributions in vehicles using acoustic reciprocal measurement which is based on the theory of acoustic reciprocity. The advantages of utilizing the reciprocal measurement to conduct the noise path analysis shows not only accurate but also efficient because all the attachment points and directions can be measured simultaneously. The frequency range can be extended from 100 to 5000 Hz.
