Hello All,
I landed on this great forum sometime ago when I finally decided to treat my room with better acoustics and this place has been extremely resourceful.
So I went ahead and made the walls soundproof as much as my budget could allow and want to treat the walls now the best I can.
I have some wooden planks with which I can make 3 broadband absorbers (6ftx3ft, 4in thick). How can these broadbands be placed to become efficient Bass Traps? Corners or against the walls?
Also, I was a bit confused about the kind of foam and density need for absorption of mid/highs. Internet research tells me that a 2"- 4" open cell PU foam with a density of around 24 - 30kg/m3 is a good absorber (the choice again depends on the room and the walls).
But the egg crate foam absorption sheets look quiet different (a little more porous) as compared to how the foam Pyramid, wedged or grid foam panels look like(much more rigid, less porous).
My confusion was - Are they both open cell PU foams of different densities? Or are they different types of foams with different densities? Or are they same? I was comparing what I understand by the 2 images attached.
Can someone help me with my question? Dont want to go blank to a foam store.
Thank you!
