Initiative denoising silence device for large generator unit

The invention provides an initiative denoising silence device for a large generator unit. The device comprises a generator unit assembly silence room, wherein a controller, a speaker and a noise collector are arranged in the generator unit assembly silence room; the noise collector is connected with the signal input end of the controller, and the signal output end of the controller is connected with the speaker; the noise collector is used for transmitting a collected noise signal to the controller; the controller is used for analyzing the received noise signal, manufacturing sound wave completely reverse to the noise signal and transferring the sound wave to the speaker to be sent out, so that the sound wave is offset with the noise. By adopting the technical scheme, the device is simple in structure and convenient to use, and can be used for collecting the noise generated by a generator unit, and manufacturing and sending out the sound wave according to noise reverse to the noise by adopting an initiative denoising technology, so that the noise is offset with the manufactured sound wave, most noise is eliminated, and control is facilitated.
