摘要：
A newly developed experimental-numerical method is described allowing the identification, analysis and optimization of airborne noise transmission paths in the field of passenger transportation systems. The method allows the separation of the structure and airborne interior noise contributions. The computer aided testing procedure is based on an indirect sound pressure level measurement approach detected by means of a multi-channel microphone system. The procedure can be applied to the detection of airborne driveline noise paths as well as to wind noise transmission paths. Due to the possibility of a clear analysis of the noise transfer phenomena, a ranking and a thorough optimization of the different noise transfer paths can be achieved.
