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.
