Why you gotta be so mean?
How much acoustic foam do you guys think I would need for a room 12'x10' I'm looking a 2'x4' pieces. I'm new to room treatment so I have no clue. Would I do the ceiling? I honestly have no clue. Any help would be great. oh and this is the room I's be mixing and recording in.

Thanks,
AMcB
 
It depends... depends on the materials the room is made of, depends on what the result you are looking for (anechoic, neutral, just kill some reflection).

None ;)

You want to treat your corners the back of the room and the first relfection points, minimum(pic1). In addition to this, you could treat behind the monitors, more ceiling points, and more points on the wall(pic2). Obviously the pictures depend on where the door is and if there is a window, but that's the basic layout.

You want to treat this room with rigid fiberglass panels(do a search in this forum) not foam.

Here's my standard blurb:

Room treatment is a deep subject, and a complete answer requires far more than will fit into a single reply here. So here's the short version. All rooms need:

* Broadband (not tuned) bass traps straddling as many corners as you can manage, including the wall-ceiling corners. More bass traps on the rear wall behind helps even further. You simply cannot have too much bass trapping. Real bass trapping, that is - thin foam and thin fiberglass don't work to a low enough frequency.

* Mid/high frequency absorption at the first reflection points on the side walls and ceiling.

* Some additional amount of mid/high absorption and/or diffusion on any large areas of bare parallel surfaces, such as opposing walls or the ceiling if the floor is reflective. Diffusion on the rear wall behind you is also useful in larger rooms.

For the complete story see my Acoustics FAQ.

There's a lot of additional non-sales technical information on my company's site - articles, videos, test tones and other downloads - here:

Awesome thanks guys. I knew it would be a every 16inch rule. I just needed some direction.
 
Panda's sketches are pretty much right on the money. You might want to consdier something thicker on the rear wall to help with length related modal issues.

What about behind the monitors to help with sbir? Would you recommend spacing rather than thicker absorption?
