How do we Reduce Sound Transmission Generated by Noisy Pumps in a Plant Room?
June 1, 2011
The obvious solution is to build an acoustic partition around the pumps but in some cases like this one it was not possible, therefore we had to find a compromise.
We could erect only two partition walls working as a sound barrier, but we lined the sides facing the pumps with a high density acoustic absorber batts (NRC 0.99), laminated with perforated aluminium foil as well as the existing walls and ceiling.
The combination of sound barriers and acoustic absorbers gave us the noise reduction we wanted to achieve at a minimum cost.
By covering most surfaces of a plant room (walls, ceiling) with the right density acoustic batts, we can reduce the noise by approximately half (10db)
