| 摘 要： | An impulse response technique has been investigated by application to the open screens for obtaining sound transmission loss. The measurements of such screens according to ISO 140 were also presented. The predicted results calculated by a model which is based on Huygen's principle and Kirchhoff's formulation have shown good agreements with the results obtained by impulse method. The method requires no specialist acoustic facilities and measurement systems can be portable.
