초록

The study about a drainpipe of water closet was performed as reduction of drainage noise for water closet. The Drainage noise is composed two characteristics. One is Low frequency noise and the other is high frequency noise. Low frequency noise is dominant in the first stage and high frequency noise is dominant in the last stage. This is due to water splashing and that is caused by formation of chamber pot. In this experiment, for the purpose for reducing the noise, we choose the hollow rubber pipe element. As a result, we reduced drainage noise about 11㏈A.
