Simulation Experiment for Adaptive Active Control of a Diesel Exhaust Noise

For controlling the engine exhaust noise at real time on line, the source, transmit mechanism and the spectrum character of the diesel exhaust noise were analysed. By using adaptive control technique of active noise, some experiments are designed to control exhaust noise of diesel. Experiment results show that exhaust noise of a diesel could be attenuated and our adaptive control technology of active noise could control diesel exhaust noise at real time on line.
