Sound isolation in attached garage
« on: June 24, 2017, 02:57:51 AM »
Hi All,

I'm about to convert an attached, basement-level garage into a practice/teaching studio for percussion. Since this room is in the basement, and these are loud instruments, isolation is a priority. I've never done anything like this, but I have been doing a lot of research.

I intend to build MSM walls. Should I leave the existing walls alone and build new stud walls inside the room, leaving space in between both sets of walls, or should I break the plaster off of the existing walls in order to create more air space, and then build new walls inside the room, without external plasterboard on them? While the latter method seems counterintuitive, the book I'm reading ("The Studio Builder's Handbook" Owsinski/Moody) seems to suggest that this method would be better for sound isolation.

The house was built in 1926, and I'm not sure about the exact construction of the existing walls, but I can tell that I am dealing with stud walls that have some sort of coating on them, maybe painted plaster.

Thank you!
