A Computer Simulation Approach to Exhaust System Noise Attenuation 900392

A computer simulation program has been developed to aid the engineer in the exhaust system noise attenuation process. This program allows for the manipulation of key component positions and configurations and predicts the resulting sound pressure level throughout the operating frequency range. This process can eliminate some of the “trial and error” approach to exhaust tuning, thus significantly reducing total development time.
