The prediction of sound transmission from air-conditioner outdoor-units in multi-unit housings
공동주택 에어컨 실외기의 투과소음 예측 및 저감방안에 관한 연구

Abstract
The sound transmission from the machine room where air-conditioner outdoor unit is located into the adjacent room is predicted and evaluated. The software package for statistical energy analysis(SEA) is utilized to determine the transmission losses of multi-layerd panels. To determine the noise level in the machine room, ray tracing method is adopted. The various sound transmission paths have been effectively identified and evaluated by the SEA tool.
