SCS 9005 Vehicle Pass-By Noise certification and Cabin Noise

Pass-by noise measurements ruled by noise standards, are approached experimentally by realizing Pass-by, Coast-by and in vehicle measurements of the sound pressure level. In most cases car manufacturers do not only want to check that the vehicle conforms or not to the regulations, they also desire to be able to analyse measurement results within the framework of research and development studies. The aim is to identify potential sources of noise: engine, power train, tire or airborne related and to reduce it. The simultaneous feature of pass-by and on-vehicle noise measurement would help a lot in performing those trouble shooting tasks.
