음향인텐시티법을 이용한 차음성능 평가에 관한 연구 ( A Study on the Evaluation of Transmission Loss using the Sound Intensity Method )

Sound transmission loss measurements on 6mm single glass were made by using the new Sound Intensity Method. These were compared with the results obtained from the Conventional Two-Room Method. In these experiments, a face to face intensity probe was used within the frequency range of 200 to 400Hz. The comparative results are discussed critically in this paper. Some special effects measured are also considered.
