Abstract
Several recent developments have improved the efficiency of noise prediction. In this paper, three methods for predicting noise are surveyed: the finite element method, the boundary element method, and the Rayleigh integral method. Techniques have been developed to quickly obtain fluid finite element and boundary element meshes from a structural finite element model, shortening the time and effort involved in creating models. Additionally, the Rayleigh integral method has proven to be a reliable method for calculating sound power. Practical examples are used to illustrate each of the three methods and show how this technology can be used as a reliable tool in the product development process.
