I know there's professional grade noise damping material but if I'm on a budget, what other options are there? I've heard of denim, roofing shingles and just cloth in general. But what other options are there for the budget foley room?
If you have 70 dollars to spare, you can get 6 2' x 4' uncovered Rockwool panels. These are huge, and it's a lot of them. All that's left for you to do is wrap them in cloth and frame them. The difference between this option and a 20-30 dollar solution is far more than the 50 dollars you might save.
The following is what I purchased for my studio: http://www.atsacoustics.com/item--Roxul-Rockboard-60-Case-of-6--RB60.html
Make sure you read up on what the needs will be for your own room. You may need a less or more dense fiber.
Be very clear about whether you are
- isolating the foley room from outside noise
- absorbing reverb/acoustics
They are different problems with different solutions
Rockwool is the most common budget acoustic dampening.
Try using a combination of sheets of fibreglass and Rockwool.
I'll second Iain's comment. I wanted to save a few bob by making my own panels for my studio. They're not tuned to any frequencies as I simply wanted to deaden the reverb in my 4m2 room. Happily turned out really well and my work translates rather splendidly to larger "proper" mix studios.
I would recomend rockwool panels wich you can put in a wood frame covered with fabric. It's not very expensive, it's modular and works quite well. I have a PDF tutorial where you can see how to make them, but it is in spanish. If you are interested I can translate ir for you.
