A Study on the Sound Paths of Air-conditioner in House
주거 공간내 공조기 소음의 전달 경로에 관한 연구
Abstract
This study was conducted to determine the sound paths and transmitted sound level in house. An air-conditioner system was selected a typical sound source. The measured transmission loss data shows that the apertures have an significant effect on the transmitted noise and comparable with the existing theoretical data. Therefore the complex aperture was substitute to quantitative apertures approximately. An effective simulation method, ray tracing and mirror image source method, was employed in the prediction of transmitted sound level. The measured results were reflected on the simulated results.
