Server Noise Problem

Server cabinet noise soundproofing

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:


  1. Enclose the cabinet in 1.2mm thick sheet metal. Make the side panels removable for easy access to the servers.
  2. Design the air inlet and outlet to minimise noise leakage.
  3. 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)
  4. Then apply Megasorber FM25 (or FG25) self-adhesive 25mm sound-absorbing foam. Its acoustic facing is fireproof, tough, durable and easy to clean.
  5. 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).
