The object of this paper is to examine the noise generating mechanism at ship construction and repair precess. To accomplish the object; A noise generating mechanism of high noise machine, which is mounted in the ship construction and repair process, was investigated. The measurement method of the noise for the machine by ship construction were investigated. The noise at the 250 points of the manufacturing process machine in the 40 processes of the 3 factories, 3 business fields was measured. The database of the noise was built from the measurement data. The major sound sources and frequency range for the manufacturing process of metal material product machine was investigated.
