초록

This paper is to investigate noise source for reciprocating type air compressors. The reciprocating type air compressors are widely used in the small and medium sized enterprise and many employees are affected and irritated by their noise during working. The investigation and analysis of the noise source were made according to the ISO 1680/1 and MIL-STD 7410-1 and noise evaluation of each part of compressors was made. Noise emitted from the intake and exhaust valve and the air receiver tank were dominant compared with those from other parts of compressor. Noise from the motor and the revolution of crank mechanism was negligible relatively with the noise sources as mentioned above.
