Air Conditioning Noise Problem

Megasorber is often asked to help reduce the noise of air conditioning units. The typical problem is:

We recommend our 50mm thick acoustic panels FM50 with a fireproof, sound-absorbing 'Soundmesh G8' facing (black). Key features:

Below are photos of typical air conditioning units:

Soundproofing Solution for Noisy Air Conditioning Units

  1. Install Megasorber D14 damping strips on the metal housing (with 50% to 60% coverage) to reduce the fan vibration noise, then Megasorber FM25 foam to absorb internal noise.
  2. Build a 'partial enclosure' around the air conditioning unit (see schematic drawings below).
  3. Line the inside of the enclosure with sound-absorbing material Megasorber FM50.
  4. Line the wall near the air con units with sound-absorbing material Megasorber FM50 so that all surfaces now absorb the noise.
  5. Seal joins (and edges) with Megasorber Soundmesh G8BK-T75 tape.

Below are some schematic drawings showing the design of the partial enclosure. This design deflects the air con noise preventing it from spreading. The Megasorber FM50 acoustic foam absorbs the soundwaves generated from the air conditioning unit.
