Sound Proof Ceiling

Dan · Feb 12, 2004 9:03 pm

I'm renovating my basement with the idea of incorporating an entertainment area.

I'm interested in sound proofing the ceiling.

Does anyone know if fiberglass batting helps? Anything else anyone could recommend?

Appreciated,

Dan

you can get accoustic bats, too, but I don't know how much price difference there is.

Connecting the plaster and floorbaords (ie ceiling and floor abvoe) to different beams helps minimise vibrations (and nosise), too

Dan has hopefully finished his extension renovation by now but for other readers, the most common & effective method to reduce noise transfer is to use a plasterboard product ( in this case for the ceiling) with an acoustic rating, available from most manufacturers - for example Boral plasterboard 'Sound Stop'.
As a (in most cases) plaster ceiling will be installed in any case, this is a cost effective solution.
Incorporating insulation batts between the floor joists will control heat loss/gain and in part add to the noise reduction value.

I saw this amazing product today. I work for a building company and one of our builders was laying an acoustic ceiling in a new showroom. They were acoustic ceiling tiles laid into a galvanised steel frame attached to a concrete substrate. They are about 400 x 400mm square, sprayed with an acoustic vermiculite type solution over polysterene blocks. They were so easy to fix once you have prepare your substrate.
Hope this helps.

Adding density to the ceiling is important in stopping low frequency noise. A great tip is to use ply off cuts (1/2 sheet from bracing panels ect) which can be found cheaply. The final ceiling is laid over it to give a seamless finish.

For high frequency noise a gap free barrier is required. This should be easily achieved by normal water proofing methods, but from the underside.

I work for an insulation company and we have some fantastic batts calld ASAB (accoustic sound absorbing batts).
We build a music recording studio at home and we have these in the walls and ceiling and there is very minimal noise outside the studio.

thanks guys, this thread very helpfull.
going to be soundproofing my downstairs ceiling, people living upstairs.
carpeting the timber floorboards made a HUGE difference, i think with soundproof rated plasterboard and batts should make it really good.

I am replying to an old thread but I have an friend who is an acoustic engineer of a multinational firm in Sydney.

He recommended Acoustiflex.

It is what is referred to as a Mass Loaded Vinyl. Essentially it is a very heavy piece of flexible plastic which dampens sound. It works better than any soundbatt around.

This small company derives it entirely from recycled product and is apparently cheaper than the competitors

They won the New Inventors award on the ABC:
