Noisy equipment is pointed out as a major cause of noise complaints and deterioration of the working environment by increasing noise pollution, whether outdoors or indoors. An effective model for noise control is the source, path, and receiver model. And the noise control at the source is known as the most economical and efficient countermeasure. In advanced countries, various policies are being enforced to reduce equipment noise level at it's source. In Korea, both bligatory and recommended rules for enlarging the use of low noise equipment are enforced together. However, the use ratio of low noise equipment is still low at actual industrial sites. This study analyses the problems of domestic noise policies related to noisy equipment, and presents a plan for improving the implementation of expansion policy of low noise equipment based on this analysis. This paper proposes that the equipment satisfying the compulsory rule be able to use the environmental certification mark, the standards of which are defined in recommended rules, to improve the linkage between the two policy measures. This thesis also suggests expanding the range of equipment to be supervised and using new noise label that has grades and shows detailed noise level of the equipment to improve environmental certification system. In addition, supplementing the construction permission system and supporting international certification system are offered to expand the use of low noise equipment.
