Portable Sound Proof Generator

In order to reduce noise and reverberation within the generator enclosure/plant room you'll need to insulate the space to absorb sound. This involves lining hard surfaces with sound-absorbing materials or installing acoustic wall panels and ceiling tiles.Seal edges with foil tape or acoustic caulk to make the seams airtight. A good noise barrier will reduce the noise coming from your generator by 15-20 decibels. You can increase the noise reduction by another 5-7 decibels by adding sound absorption, like Mega Zorbe, inside the generator box.
