I have room for noise and want to act on that impulse

codyfarmer · 06-17-2008, 10:31 AM

So, I just moved into a new house the week before last and have a music room I'm going to completely make ridiculous.

I want to put sound proofing in the room, but don't want to hang egg crate bed liners. Anyone have a good place to get sound proofing stuff for a decent price? I need this because I'm going to eventually add ---->

Also, if anyone knows a super sweet place to get a decent bar drilled out for tap's, kegerator, etc, that would be super sweet for my music room too.

Thanks!

Sound proofing requires mass. Also if you can keep the walls, ceiling , and floor physically isolated from the rest of the structure it will contain the sound most effectively. Basically build a room within a room and isolate it with floating mounts (springs, rubber, shock-absorbers, etc.). This is the way large recording studios build their rooms. However, since you are in a house, your going to have to modify this approach.

Windows and doors are going to be the biggest sound leakers. I once made panels to cover windows out of two sheets of plywood with a layer of sheat-lead between them. I used carpenters glue on both sides of the sheet-lead and then screws through the plywood at 4" to 6" intervals. The screws alternated starting from one side of the "sandwich" then from the other side. They were long enough to penetrate about 1/2 way through the far piece. I used these to cover jalousie windows and had a power trio rehearsing in the room, but outside all you could hear was a bit of the kick and low bass--no neighbors ever complained and they were close, less than 30' away.

A friend of mine built a rehearsal room out of a single wall garage by putting plywood over the inside studs (the 2x4s that run vertically every 16") and filling the space with sand. Those walls transmitted very little sound. The ceiling was less sound proof, but he tacked a couple of layers of carpet to it and that helped. He would crank a 100W double stack and blow out his ears, but the neighbors didn't hear much on the outside.

Final note: Bass frequencies are going to be the hardest to contain--that's what you need the most mass for. Egg crates don't sound proof anything, but they can be useful as acoustic treatments in the room--they break up reflections and absorb some highs. The old-style stuffed mattresses also soak up high frequencies and I've seen them added to thin paneled doors to help stop sound leakage--not as effective as a double hung door with airlock, but better than nothing.

Hope this helps,
Roger
