A study on the Measurement of Field Transmission Loss through Doors in Buildings Using the Surface Intensity Method.

Surface Intensity 법에 의한 건물내 출입문의 차음성능 현장측정에 관한 연구

The surface intensity method is a relatively new tool which can identify the noise source or path and measure the radiation power. One microphone and one accelerometer are used in this new technique. In this study, this new technique has been used to measure the field transmission loss trough doors. The results of the experiment indicate that the surface intensity method produces reliable data and can be applied to the transmission loss measurement.
