Design for the Simulation Experiment of the Electronic Muffling Control System of Engine Exhaust

The technique of active noise control and the design and building of the experiment platform of active noise control are discussed. This thesis puts its emphasis on the control system of the experiment platform of active noise control and the implement of recording, playback, separate control of the two tracks and volume control. At the end of this thesis there is a theoretical experiment of active noise control, which has confirmed the efficiency of the platfom and its control system.
