Damping plasterboard structures to reduce ringing


Active Member
Hi, I hope I'm not asking a question that's already been answered but a bit of searching hasn't unearthed an answer yet...

I've built a couple of plasterboard structures in the living room, a pelmet to hide projector screen and a bit of boxing in under the stairs. But I'm a bit worried about any ringing/stored energy in these structures.
The room is pretty inert today as all the walls are blockwork, the last thing I want to do is end up with that sort of ringing sound you get when the room is energized and then there's a sudden pause in the music or film. Particularly as I plan to spend a bit of money of room treatment elsewhere.

I've been looking for self adhesive damping materials, something like dynamat for cars, but ideally a bit cheaper. But there does't seem to be anything aimed at the domestic market that fulfills this function.

Is anyone aware of such a product? I don't really want to go down the road of plaster board with the massloaded vinyl adhered to the back unless I have to...

Any DIY options I can bond on the back of the boards with green gunk?

Ideas appreciated....

call Gary at custom audio designs and ask about Tecsound 50 sheet, that might do the trick
