Soundproofing a wall with a ventilation unit attached
« on: September 30, 2016, 02:06:56 PM »
Hello,

Hope you're all well!  I would like to ask a question about soundproofing a plasterboard wall.

I have a 2.49m x 0.65m (height x width) wall which separates the utility cupboard and the bedroom.  There is a ventilation unit wall mounted in the utility cupboard and it is quite large.  Overall, there is only enough space for a finger between the back of the unit and the concerned wall, and about a finger width between the side of the ventilation unit and the side walls of the utility cupboard.

I'd like to find someway of soundproofing this wall such that there is no low frequency noise going through the wall.  Since the ventilation unit is wall mounted, you can feel a vibration on the bedroom side of the wall which I think is causing the noise.

There is very little space around the ventilation unit, but there is enough for say 5-10mm of material, though I'm not sure whether the wall connection will be an issue.  I'm not sure whether there is much sound insulation either in the wall, but I'm reluctant to bring down the plasterboard since it is a new build flat.

Please could someone give me a solution for my current problem?

Thanks lots,

Jon

since the unit is wall mounted the only option you have is to build another wall (double wall construction) or clip and channel the opposite side and you would have to remove the plaster.
