Abstract
This paper expatiated the principle of sound intensity measurement,and simply explained how to measure noise with sound intensity measurement and identify the concrete position of noise according to the measurement results.To a certain engine,the paper carried on a sound intensity measurement research,got the sound intensity cloud diagram and noise distribution of the engine,and found the main parts of noise source.
