Can be handled from the following aspects:

1, sound insulation

In terms of noise control and sound insulation, we can choose sound insulation cover and sound insulation room to control the noise source in a closed space and control its outward diffusion. In addition, the use of sound insulation materials in the sound insulation room or cover can effectively isolate the noise generated during the operation of the fan. Considering the ventilation and heat dissipation of the equipment, a silencing louver can be installed; Some air ducts are soundproofed, and the air ducts are soft-connected.

2. Sound absorption, silencing and noise reduction

Sound-absorbing materials and silencers can be used to sound-absorb the ceiling and sound-insulating cover of the above-mentioned sound-insulating room, so as to achieve sound-insulating effect and achieve the best sound-absorbing effect. The sound-absorbing materials that can be used include sound-absorbing board, sound-absorbing cotton, polyester fiber sound-absorbing board and so on. The related parts of the fan can adopt the chip muffler or the compound combined muffler to solve the noise propagation problem at the noise source.

Step 3 Use shock absorbers

If the mechanical vibration noise of the fan is too large, you can choose to use shock absorbers, shock absorbers or shock absorbers. On the one hand, it can prevent the fan from generating vibration noise in the working process, on the other hand, it can reduce the noise from the transmission path. When using the shock absorber, pay attention to the use of soft connecting materials when connecting the machine to avoid greater fan vibration and noise pollution.

If you want better noise reduction effect, it is recommended to consult a professional acoustic noise reduction company and deal with it according to the targeted noise reduction scheme.
