Which material to use in acoustic panels?

[renemartin]

Hi, I want to make 4 DIY acoustic panels.
I've read on reddit that the important thing is the thickness of the material, not have to worry about material type itself.

But I have no experience, what should i choose?
I like that polyester thing or rockwool 'cause of the thickness they provide. More leaned toward polyester 'cause less harmful then rockwool I guess.

What y'all think? Thanks

rockwool

rockwool

I just made 3 for ceiling and 2 for behind bookshelf speakers. I used rockwool and came out nice.

 

[harleydave]

Forgot, made 1 for behind center too.

 

[renemartin]

great! thx for feedback and photos guys.

 

[renemartin]

should I buy 12 or 16 cm thick rockwool?

 

[DonH56]

Rockwool, or Corning OC-703 are commonly used to make panels. If you need to absorb bass, get the thickest you can fit and live with. I used 4" (10 cm) panels on the sides and 6" (15 cm) at the front and back, with angled 6" panels across the front corners (no room in the back) that had an additional 6" behind. Also ceiling panels. The link in my signature has pictures of my system and room.

This is useful.

To build "reasonable" absorbers, you need either the absorption coefficients at different frequencies for each material used or, even better, the length-specific flow resistance, then you can simulate the absorption coefficient versus frequency yourself with the appropriate tools.

Simply attaching any rock wool to the wall can have negative effects, especially in the upper base to upper midrange area.

To get you started, translate this website, it contains many tables with length-specific flow resistances, link to simulation tool and simulations of many different absorbers:

As he said every material has is properties in my case in my room i used rock wool and rock glass, the fibers cant go anywhere because i used a very ligth material like fabric,

 

[Justdafactsmaam]

JJ recommends rock wool

 

[ozzy9832001]

I use rockwool and pink fluffy depending on what I'm trying to do. I find for very thick traps (great than say 10") mixing pink fluffy with rockwool gives the best result.
