Abstract
To estimate the rate of noise contribution caused in each part of a vehicle in the course of a pass-by noise test. researches precedent have been made to study characteristics of nearby radiation noise measured on both sides of cars in a stationary state. With different revolutions per minute of engine. 2.800rpm and 3.200rpm respectively, in the measurement area of pass-by noise, the experiments have been conducted 7.5 meters away from the central axis of the test vehicle to study direction radiation according to frequencies. The results can be applied to reduce vehicle noise.
