Abstract
Noise level prediction computer code ACOUST/BOOM has been developed to analyze the sound pressure radiated by a vibrating structure and calculate the acoustic resonance of the field. The program is based on the numerical analysis computation of a sound wave equation in a three-dimensional field using the boundary element method. The boundary element method uses simplified input data, reduces computation time and cost, and produces highly accurate results.
Applications has been performed on sound radiation analysis for engine oil pan, engine head cover and horn type speaker and also on the acoustic analysis for sedan compartment models, which confirmed the accuracy and the versatility of the program.
