Estimation of boundary parameters and prediction of transmission loss based upon ray acoustics

Estimation of boundary parameters and prediction of transmissioll loss usillg a sound propagation channel model based upon ray acoustics and sound propagation data collected in field experiments are presented in this paper.Comparison between the prediction results and the experiment data indicates that the adopted sound propagation channel model is valuable,both selection and estimation methods on boulldary parameters are reasonable,and the prediction performance of transmission loss is favorable.
