I live on the top floor. Who should I complain about the noise of the fan?

The best way is to discuss with the property management. If not, go to the residential street property office and ask for compensation.

This is the neighboring right stipulated in the property law, and every citizen has this right, and no one can infringe upon it.

The original fan room can be soundproofed, and the fan room can be transformed into a completely soundproofed room, and sound-proof doors and windows, sound-proof barriers and sound-proof walls can also be used. To block and shield the noise, which helps to reduce the cost.

Fan pipes also produce noise, including internal air impact noise and pipe vibration noise. Sound-absorbing cotton can be used to wrap up and isolate air impact noise, and damping sound-insulating felt can also be used to isolate vibration caused by impact.

The operation of the fan will cause certain vibration, and the treatment measures include laying floating ground on the fan foundation or installing damping foundation to reduce the sound transmission of the vibrating solid structure.

The noise at the air inlet and outlet of the fan is generally higher than that at other positions 10 dB, so installing silencers at the air inlet and outlet can effectively reduce the aerodynamic noise generated by the air inlet and outlet. The type of muffler can be impedance compound muffler, and the noise reduction can reach more than 25 decibels.
