Comparing with the existing test methods and limits on vehicle exterior noise in China and abroad, the latest progress in pass-by noise measurement in foreign countries is exhibited, and the direction of improvements to be achieved in China is presented. To provide a reference for identification of main noise sources of automobile in an efficient and accurate way, common analysis methods adopted for discrimination on a moving vehicle are discussed. To supply a comprehensive frame for more profound and focused model in exterior noise prediction, numerical simulation methods applied in different moving conditions are systemized.
