The purpose of this study is to analyze the sound insulation of party wall between housing unit according to setting of built-in chest of drawers. Nowadays, residents who pursue a high quality and diversity of the life want to new plan for their apartment. By a survey, it was investigated that residents desire to establish built-in chest of drawers when they rebuild or re-model apartment. In this study, we manufactured built-in chest of drawers in front of party wall in Mock-up house to analyze the sound insulation effect when it set up. Also, we made an experiment on sound insulation effect according to amount of sound-absorbing materials. As a result, in case of setup built-in chest of drawer on both surface of party wall, the sound insulation capability becomes a higher about 9 dB and in case of setup on one surface of party wall, it becomes a higher about 4 dB than only concrete wall's. When rate of loading in built-in chest of drawer is 100%, single-number quantity for airborne sound is 58 dB. In case of 82%, 60% and 0%, it is 57 dB, 56 dB and 54 dB respectively. |
