Identification of Noise Sources on a Diesel Engine Using Sound Intensity Measurements

Abstract:

According to the analysis of acoustic signals and vibration signals measurement, an investigation of the noise source identification in a diesel is presented, and the noise level of the diesel is comprehended. With the sound Intensity method, the major sources of the exterior radiation noise of the engine are surveyed. The research provides the reliable basis for the engineering practice to reduce the vehicle noise level.
