Abstract
This study aims to propose appropriate evaluating method of noise emission from water supply and drain installations in apartment bathroom. Because KS(Korean Standard) about water installations noise in apartment bathroom only are establishing the measurement procedure of it, Evaluation and rating procedure is necessary to improve the sound insulation performance of the apartment and to reduce the apartment dweller's unsatisfaction with the noise. Thus, this study reviewed the standards and evaluating methods about the water supply and drain installations noise of many other country. We measured the noise emission from the installations in many apartment bathroom, and then we calculated the noises to dB(A), N, NC evaluated numbers. We analyze the coefficient of the corelation among the evaluated numbers to induce the appropriate method. As a result, the dB(A) method is most easy to evaluateing and very high corelated wth N and N index, So the dB(A) method is suitable to be adopted KS evaluating procedure of noise emission from water installations in apartment bathroom.
