Abstract

The prediction of sound levels in vehicles and the environment is now a common practice in engineering. This has been made possible by the development of powerful tools based on boundary element techniques. These "first generation "systems provided the user for the first time easy to use tools to predict sound levels. This paper will describe a "second generation" acoustic system based on boundary elements which not only enhances the accuracy of the modelling, but also provides powerful diagnostic facilities to enable the user to identify the main contributions to the sound intensity at a any point of interest. Applications are presented. 1.0 Introduction The products of many industries can benefit from improved acoustic design. The same technol- ogy which has been successfully applied to simulate the performance of structures c
