Abstract: In this paper,the distribution of engine surface noise is measured by means of complex acoustic intensity method.Surface noise sources of S493Q diesel engine are identified.After the main noise sources are located,noise suppression measurement is adopted,and noise suppression effect is obtained.

Key words: diesel engine, noise sources, complex acoustic intensity
