The noise frequency spectrum of the axial flow fan is wide, and the noise low-frequency component of the centrifugal fan is large. When the noise of the fan is at a low wind speed, sound is mixed due to poor sound insulation of the pipe wall; at high wind speeds, it is the noise radiated by the vibration of the pipe wall caused by the fan noise, and also the noise generated by the resonance of the pipe wall caused by the disturbance of the air flow in the pipe. The magnitude of the regenerative noise at the end of the wind pipe depends on the wind speed, which should be kept as low as possible, and reduced using diffusers and dampers if necessary.
