Soundprove

[Sebg]

"Soundproofing" means sound insulation - keeping outside sounds out and inside sounds in.

Pink bats and other "soft" materials are usually used to affect 'room acoustics' - that is, how the sound behaves in a room. Almost nothing to do with sound insulation. And expanded polystyrene is almost useless for acoustic purposes - it provides minimal sound insulation and no sound absorption.

So pink bats is the go then?

Are you trying to keep sound inside the room, or trying to make it sound better in there?

If you're trying to keep sound in/out, then go for drywall on a separate framing system.
