지하기계실에서 발생한 아파트 및 인접거주지역의 소음 발생 원인 분석 및 해결 사례

Apartment and large residence buildings are necessary to ensure a comfortable noise/vibration environment. So. it must be performed a anti-vibration/noise evaluation at early design stage, such as utility room arrangement, machinery installation method and so on. In this paper. environment noise status on problem areas, which was issued by resident. was investigated to understand the noise transmission property generated from underground machinery room and to device a optimized countermeasure in order to enhance noise environment. Also, the measured noise levels before and after modification works are compared to confirm the effectiveness of proposed countermeasure.
