Painting Acoustic Foam
I was wondering if anyone has any experience with coloring the typical charcoal foam. It seems to me that simply spray painting it will close the open cells on the face of the foam and increase the reflectivity of sound from the foam. Is this true? Is there a way to color the foam (I don't want my place to be that dark)? I know I can find white melamine foam, but it is more expensive than what I've been able to find charcoal (colored) foam, and my local music shop only has the 2" Auralex in purple or burgundy.

You may be able to dye it, (and I'm not saying you should)...
but I certainly wouldn't paint it... for the reasons you suspected... that it would likely be detrimental to it's function.

The better option would be to cover it in acoustically transparent cloth to hide it.

agreed. Muslin would be a decent choice for this.

I used fabric (not fleece, but similar) to 'dress' my self-made gobos. It works really good.

You are absolutely correct. However, since you're considering changing the color anyway, you should look into 2" Owens Corning 703, which sounds better than foam, and can be easily covered with cloth, plus it's much less expensive. We have both in our studio. Auralex is super easy to use (spray or squirt adhesive, stick to wall, get to work), but the 703 sounds much better. You do have to treat it. On another note... are you sure you need absorption? You might want to look into diffusion first. In my experience, you need both... and generally bass trapping as well. Good luck! Corey
