Abstract: The main noise source and the frequency spectrum characteristics of a piston-reciprocating air-compressor are analyzed. And an effective synthetic management method is introduced. With this method, a strategy of noise control is designed and implemented for a practical engineering project, which has been checked and accepted by government and yielded good economic and social benefits.

Key words: acoustics, air compressor, noise source, spectrum, noise control
