Simulation of Sound Field Using Boundary Element Method

摘要

There is a great need for analyzing sound fields more accurately according to the development of compact, lightweight, and high-performance machinery. 'MHI-Sofia' (Sound Field Analysis and Simulation Program) has been developed to solve the problems using the Boundary Element Method. It enables people to predict the sound pressure and sound intensity using machine surface vibration modes. The calculated results of sound radiated from a sphere, a flat panel, a compressor or a bridge agreed well with the experimental values.
