APAMAT을 이용한 실험에서 공기층 삽입이 차음재의 투과 손실에 미치는 영향
Effect of Air Gap Insertion on Transmission Loss of Sound Barrier in APAMAT Measurement
초록
This paper presents the effect of air gap insertion on the results in measuring the transmission loss of sound barrier by using APAMAT. The measured results show that air gap insertion improves transmission loss as by two-room method or intensity method. The measured results are compared with the predicted transmission loss using MATLAB GUI program based on the transfer matrix method. Predicted results were found to be in reasonable agreement with measured results.
