Server cooling fans generated a constant humming noise with levels up to 83 dB(A). The noise was particularly annoying to the office workers
because the peak frequency level was around 800Hz to 1,000Hz (see understanding noise levels).
Soundproofing Solution for the Server Cabinet
Economic Soundproofing Solution
Apply Megasorber FM25 (or FG25) acoustic foam to the sheet metal enclosure.
Super-Quiet Soundproofing Solution
Apply Megasorber D10 (or D14) vibration damping sheet to the sheet metal enclosure.
Then apply Megasorber FM25 (or FG25) acoustic foam.
Hear how Megasorber's soundproofing products installed on a Server Cabinet can effectively reduce noise:
Enclose the cabinet in 1.2mm thick sheet metal. Make the side panels removable for easy access to the servers.
Design the air inlet and outlet to minimise noise leakage.
For a super-quiet soundproofing solution, line the metal panels of the server cabinet with Megasorber D10 (or D14) self-adhesive vibration
damping sheets. (Optional)
Then apply Megasorber FM25 (or FG25) self-adhesive 25mm sound-absorbing foam. Its acoustic facing is fireproof, tough, durable and easy
Seal joints with Megasorber G8BK-T75 acoustic tape.

Soundproofing Project Results
Megasorber's soundproofing products targetted the most annoying of the sound frequencies, reducing them to comfortable levels.
Noise levels were recorded before and after the acoustic treatment at 1m away from the cabinet and 1m above the ground. The final noise level was
well below the office ambient noise level, at 49dB(A).
