Plant Room Noise Reduction

Reducing Plant Room Noise

Generator or plant rooms tend to have high noise levels (up to 115dB(A)) with noise concentrated in the low to mid frequency range. Without proper soundproofing treatments, the high noise level can cause discomfort to nearby facilities.

Megasorber Quiet System

This system addresses both absorption and transmission loss, through use of a noise barrier layer in addition to absorption panels.

Install battens on wall and ceiling of the plant room and fix a sandwich of Megasorber B8 and 2 layers of plasterboard / ply / MDF / FC sheet. Adding mineral fibre batts in the cavity will increase the performance of this system. Install Megasorber P100 or FM100 to the outside of the sandwich layers, using A200 adhesive. Mechanical fixing is recommended when installing in an overhead position.

The above schematic shows a system rated at Rw 61 – based on noise levels heard outside the plant room. Internally, you can expect a reduction of 6-10dB(A).
