room acoustics

[varunkapahi]

i just shifted all music equipment and a computer to a new room, here i have a drum set, a bass, keyboard, and a computer. there isnt much of sound absorbing stuff in the room else than a couch and a curtain over a window and the room is already totally crammed up so i have no more space to get more couches or anything to absorb all the reflections in the room.

right now playing bass isnt much fun because the lows are booming so much, i have eq'd out a lot of lows but its still booming. so i need to make a list of things which would absorb sound and not take much space, for that i need your suggestions. right now i am gonna get

1. wall to wall floor carpet
2. more heavy curtains (maybe some just on bare walls for no other reason but to absorb sound)

please help me make this list longer. but remember there is'nt much space left to keep anything more, there is some but little left you know say about 3-4 square feet and about 1.5 sq feet in another corner and then it will be super cramped

edit: i dont want to spend a lot of money on professional acoustic treatment since this is just a make shift practice room

first of all, heavy curtains and wall-to-wall carpet won't do anything to help the boominess, because they only absorb very high frequencies. To control boominess you need something to absorb low frequencies -- aka Bass Traps.

And you need a lot of them.

Most cost effective way to get bass trapping is to build your own, and the best performance per dollar I've ever seen in DIY bass traps comes from wrapping 2'x4' x 4" 6lb density rigid fiberglass boards in an acoustically transparent cloth and mounting them so that they straddle the corners of your room (forming a triangular-shaped air space behind them).

There's a great article here http://www.ethanwiner.com/acoustics.html that goes into more detail.

I feel your pain. Minor room treatment (curtains, carpet, etc.) won't help much and could actually hurt by absorbing more highs and upper mids and leaving you the low end. The only two things that helped me with that were dialing the lows and mid bass way back and moving my bass amp out of the corner.
