Hi all. I am in the process of giving our basement studio unit which is located under our lounge/kitchen an overhaul. The plan is to frame out the exterior block walls, insulate and line with ply and white wash. Have ripped the ceiling out so can run new cables and lights etc and plan to insulate between the ceiling joists and then thinking of installing ply ceiling. Am wanting to minimise noise between the two levels so wondering what insulation people would recommend and if the ply ceiling would help with sound proofing. Any ideas or experiences would be appreciated. Cheers

There are noise dampening batts available. Rather than ply, what about two layers of gib?

We used 2 layers of gib to soundproof between the lounge and other rooms, it works really well.

Google how to. Theres lots to consider to get effective soudproofing. Gib or ply has to be railed or else its a waste of money.

Forget the details now but there are several elements to get effective sound-proofing. Ask your building supplies merchant.

Heres the answer, this is the best of the best. Rhondo ceiling battens fitted using the rubber clip type of brackets. Sound proof insulation between the ceiling and next floor. 1 layer of 13mm gib noiseline Soundproof caulking around the perimeter. A second layer of 13mm gib. DONT use recessed lighting. We have just done a new home this way and its as good as you will get unless you go for a second floor framed separately from the ceiling structure.

We used noiseline Gib it does work very well.

#6 is dead on plus use Woolbloc (or Terra Lana x Mitre10) as it has the best accoustic insulation of any.

insulation has no acoustic value. Its how air movement and vibration happen. For gib noiseline to be effective or a barrier to the vibration of noise, it has to be applied properly. If you screw to existing studs you just wasted your dollars.

+1 sound moves with air. recessed lighting has loads of gaps for air and noise to go through, but holes for wires for surface mount lights allows noise to, if unsealed.
you can put a layer of moisture permeable air sealing wrap on the ceiling and seal up anything thats goes through it.

Nonsence.
Accoutsically rated insulation does two jobs - it reduces the air-transmission of sound by minimising air movement and it absorbs a broad spectrum of sound frequencies into it's physical material. Applied properly it is well worth the effort.
Indeed, if insulation had no accoustic value, can you explain why the manufacturer specs include an Accoustic Rating figure? It's measured in rayls and if you can be bothered, read this: https://en.wikipedia.org/wiki/Rayl

Bradford Gold has a reasonably good acoustic rating, as do other products.

Insulation is part of many of the sound rated Gib Systems , as is directly fixing to framing .
Granted , a ceiling fixed on hangers , or wall linings suspended off the framing on rail is far better . better still with insulation .

i meant aucoustic insulation doesnt have any sound reducing qualities, great insulation properties.

30k for half my house to be noise reduced following a qualified acoustics engineers plan for my house. Let down in places by a dumb builder who took shortcuts, that had to be redone. So been there done that.

prefer the opinion of an acoustic engineers to your nonsense, and more bothered than you will ever comprehend.

Sounds like the 'experts' stiched you up and I'm perplexed why you bought them in if you know so much about the subject.
Given that you claim to know all about it - please explain why the manufacturers of insulation quote the accoustic properties of their products. Further, please explain why we fill the walls of audio booths with these materials.

Im sorry , but you are wrong on that one .
As a rule , the properties are not great , but they do play a role in many sound rated systems .
We've installed sound insulation directly onto walls inside noisey factories to isolate areas and the Db levels have dropped drastically
Inside wall cavities are less effective of course , but there is still a level of absorbtion

Bradford Gold has a higher acoustic rating than some of the black acoustic batts. Read the information available !
