Acoustic Foam Thickness (Too Thin?)

[Rod Norman]

The thickness difference is about two inches. Staggering thicknesses is a good idea. The real question is what are you using it for? If you want sound isolation from other rooms, the acoustic foam does little. If you want to tame early reflections within the room, you have the right idea. I also suggest stapling wadded up fabric onto pieces of long plywood and leaning them up in the corners at an angle with the fabric wads pushed into the corner. This will tame bass frequencies. Good luck,

A year ago I purchased 8 2ft X 2 ft panels of acoustic foam (eggcrate design) for use in an isolation cabinet. I'm now thinking of using these to treat my bedroom (9ft X 10ft) for mixing. The thing is, they're only 3 cm thick and am in a bit of a dilemma as to whether I should stick with these or spend money on thicker tiles. Are these tiles sufficient or would I need to replace them with the latter? I was thinking as a compromise that I could maybe ditch 4, and replace them with a ce of 10 cm thick tiles.

No it won't.

On placing corner bass traps:

There may be only 3 wall-wall corners in your room, but those aren't the only corners are they? Wall-ceiling corners can be great places to put traps because they don't take up floor space.
