Abstract
In the case of newly developed stud which has more performance of sound transmission loss, it is expected that sound would transmit through runner than stud. so we developed construction method of runner and stud. As a result, sound transmission loss is improved about 2 dB by using this method. But this construction method could be applied to only newly developed stud. In addition, sound leak of wall joint is about 2 dB, and it could be improved by using rubber gasket at joint.
