Using existing insulation as sound absorbers?

379 Views 7 Replies 3 Participants Last post by  jf1
I`m building my HT-room in the basement. My room is about16x11x7' so I don`t have the space for alot of big absorbers. Between the joists there is about 8" of glass wool heat insulation. I plan to use wood panelling for the ceiling, and my idea is to make "windows"in the panelling and use the existing insulation as an absorber. Would this work?


The "windows" could be covered with some nice fabric . The same could be done to the walls, but here I`m only using 2" of heat insulation. I will probably need some additional bass treatment? In the back of the room I could probably fit bass absorbers in the corners.


The floor will be concrete, probably covered with ceramic tiles. I thought of carpet, but after some reading (eg. the article by Ethan Winer at http://www.recording.org/users/acoustics/ ) I think that tiles will work.


I plan to build bass absorbers in the back corners of the room.

Thanks Ethan!

Thanks Ethan.


I need to peruse your website in more detail (there is a lot there to digest).
