摘要： The noise produced by a motor can be easily controlled because its speed is from 0 to 1000 rpm. The noise of a motor is mainly caused by the interaction between the stator and rotor, and the noise can be reduced by controlling the speed of the motor. In this paper, we use a motor to produce noise and control it by a computer. The motor is driven by a computer and the noise is measured by a microphone. The computer controls the speed of the motor and the noise is reduced.
