Acoustic Ceiling Tiles

(1/2) > >>

Kshah:
HI guys,

Gonna be dipping my feet into this well soon.

Been busy setting up the man cave and had the ceiling redone.

Whilst at the supplier I noticed acoustic tiles - 1200 x 600 by OWA https://www.owa.co.za/product/sandila-n-2/

There are many options, colours and designs

Has anybody used these to any effect?

Could these be of any value as backing as opposed to using Masonite?

I know that @Vince MacMahon has had a hand at making panels?


And the sales people there also enthused about the free hanging baffles: https://www.owa.co.za/product/selecta/ and https://www.owa.co.za/product/freestyle-baffles/

I wonder how these could be used

I see they are 15mm thick.

With a 35db sound absorption propery, they will make the room quieter in as much noise comes through the ceiling.   Beware not to make the room too lifeless.  A certain amount of natural reverberation is desirable

Rodney Gold fitted some ceiling tiles in his house in Panorama and said to me at the time that he thinks he over-did it

Most of my exterior noise comes in via the windows.  When I fitted 2-layer glass some years back, this made a huge difference

Greyman:
I assume the sound reduction amount of 35db quoted is when the product is installed as part of a soundproofing system as that is a high amount. Designers normally recommend products with a minimum NRC of 0.7 in order to make a meaningful difference. With an NRC of just 0.5, the price to performance ratio does not make sense in my humble opinion. The free-hanging baffles are 40mm of glass wool with a density of around 17kg/m2. The density is great but if you have the space you should go much much thicker to affect a wider band of the frequency response.

Vince MacMahon:
For what it’s worth:
Matome had these for a day or so and removed with haste!

Rather look elsewhere for room treatment.

If you have carpet, you can leave the ceiling reflective. Those tiles are very dense and thin, so they absorb only a small part of the frequency spectrum. I would advise against ceiling tiles.

Rather good thick cut pile carpet and then depending on how alive / dead the room is you can leave the ceiling or do a “cloud” at the reflection point. Use diffusion if you have enough absorption in total, or absorption if you need more, or if you have a low ceiling or speakers with poor off axis response.

Mostly though, if you have a thick carpet, I would leave the ceiling to last and mostly you’ll find you don”t have to touch it.
