Hi, I have two adyacent rooms divided by one 15 cm thick brick wall… I got a 1×1.5 m hole for the acoustic window… One of the rooms will be my live room and the other will be the control room. I would like this wall to be able to block drums sound from leaking to the other room.

So, I´m thinking about installing an extra layer to increase the soundproofing (wood stud+mineral wool+durock+sheetrock or plywood). I found somewhere about resilient channels to decoupling the two walls but I wonder about two things:

1. Is this idea of adding an extra layer (considering the materials I listed) attached to the brick wall a good idea? will it improve soundproofing? is there a better option?
2. Regarding using resilient channels… Is this worth it since the acoustic window will sit over the brickwall hole as well as over the stud hole?

Any extra recommendations?

M, Neither of those options will work. You need to match the density of the existing wall structure for any “hole plugging”. Add mass to equal the mass of your existing wall. Seal all edges with a liquid rubber material.

They had developed a rigorous process to minimize manufacturing errors and production delays. Drawings for each perforated panel can be provided to make sure the panel is correct for the first time. This process is invaluable because the potentially expensive mistakes may be found on paper before they become serious problems in the construction site.
