Abstract
Recent trend of installation of highly efficient and high Power engine in vehicles has increased complaints about exterior noise being made while travelling. To examine the sources of outer noise of vehicles controlled by regulations. using lead wrapping method. Pass-by noise tests have been conducted as opening each defined source one by one. The sources of outer noise have been found and the rate of noise contribution has been produced. The results of the tests have been applied to put noise-reducing objects in the order, and counter plans effective to reduce noise have been devised.
