Abstract: According to the engine exhaust
noise spectrum characteristics,an experimental system based on the
characteristics of Active Noise Control Technology and the simulation of
electronic technology the simulation of electronic technology was put forward
in order to enhance engine's power and save fuel,in which the noise
cancellation mechanism of the system was also studied.The experiment showed
that the effect of noise attenuation is obvious.
Keywords: Engine;Noise Control;Active
