대형기계 및 고출력기계의 소음평가에 관한 연구 A Study on the Noise Evaluation of Large and High Power Machine
pp.25-31
The object of this project is to prepare the countermeasure of the health care according to investigate and database the basic information of the large machine and high power machine. To accomplish the object; The dimension and noise of the large machine, which is mounted in the factory, was investigated. The prediction and measurement method of the noise for the machine by manufacturers were investigated. The noise at the 500 points of the large machine and high power machine in the 40 processes of the 6 factories, 6 business fields was measured. The database of the noise was built from the measurement data. The major sound sources and frequency range for the large machine and the high power machine were investigated. The noise effect by the large machine and the high power machine was investigated.
