Is it Overkill

I have a question. When treating a room just acostical purposes, no Isolation. How much treatment is required. I was looking into covering the entire walls with OC 703 in cloth covered panels. Would this be necessary. If not, what is the ratio of treatment need with the sheetrock

CAN ANYONE HELP ME?

Your question is too vague and easily answered by yourself be reading the Recording Manual on off the main page. Andre

Read the stickies to get a more complete idea. In short, no. You don't wan't the whole wall covered. 1 - it's too dead in the highs. 2- you do nothing to address the rest of the frequency spectrum. There is no single right answer for the percentage. Without knowing how the room was constructed, what other things are in the room, how many people, what kind of seating, where the speakers are, where the listening position is, there is no way to determine what is 'right' for you.

A booth should generally be deader than a CR, and a CR deader than a tracking room; a good start for a rectangular CR would be to put about 3' wide 4" thick fiberglass or rockwool (NOT standard house insulation) across the corners floor to ceiling, then more spaced 4" off the wall in front of the speakers (opposite the listening position, that is), a suspended "cloud" of the stuff over the mix position and centered between your head and the speakers, more yet across the rear wall (behind your head), and 2' x 4' pieces on the side walls where a mirror would let you see either speaker. Then, stop and listen to a LOT of music; if it sounds good, it is. If not, alternate patches of the same absorbent on opposing side walls (if you have absorbent on one wall, leave the corresponding part of the wall opposite BLANK) - this will help control flutter echo. IF you have carpet, consider laying some plywood on top of it temporarily; if the sound improves, don't leave the plywood; instead, rip up the carpet and do the floor in something (anything) reflective. That should give ANY room a good start; however, even two identically built rooms aren't truly identical, and the only way to get it right is LISTEN, then correct the wrong things you hear... Steve
