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

Abstract

We present an estimation of boundary parameters and prediction of transmission loss using a sound propagation channel model based on ray acoustics, and sound propagation data collected in field experiments are presented. Comparison between the predicted results and the experiment data indicates that the adopted sound propagation channel model is effective, both the selection and estimation methods on boundary parameters are reasonable, and the prediction performance of transmission loss is favorable.
