1. Reduce exhaust noise: Using a muffler can generally reduce exhaust noise by 30-50 decibels.
2. Reduce fan noise: Use resistive chip muffler.
3. Sound insulation, silencer, and sound absorption treatment of the computer room:
3.1 Sound insulation of the computer room: Except for the necessary internal wall observation windows connected to the observation room, the rest Windows should be removed, all holes and holes should be tightly sealed, and the sound insulation of brick walls should be above 40 decibels. The computer room doors and windows adopt fireproof and soundproof doors and windows.
3.2 Air inlet and exhaust: The air inlet should be equipped with a resistive piece muffler to naturally balance the air volume in and out of the computer room and achieve obvious ventilation and heat dissipation effects.
3.3 Sound absorption treatment: The five walls in the machine room except the ground are treated with sound absorption. According to the spectral characteristics of the generator set, a perforated plate resonance sound absorption structure is adopted.
Vibration isolation: Through vibration isolation, the excitation force generated by the equipment is isolated by the vibration reduction device, so that the solid sound is effectively isolated.
Sound absorption: Use sound-absorbing materials to absorb sound energy and reduce the reverberation sound in the computer room.
Sound insulation: Take sound insulation measures for the doors and windows of the generator room and replace them with professional soundproof doors and windows.
Sound silencing: Install damping mufflers at the inlet and exhaust ports of the computer room to reduce noise leakage.
