So I picked up a drum kit recently and have a few questions about making a practice area that wont piss off the neighbors. I was in a half ass attempt of a band a while back and we used to practice in the basement which led to complaints from neighbors and an occasional visit from the po-po. Ive now got an extra bedroom available upstairs and am tossing around the idea of making a practice area/ studio that I would need to sound proof on a very tight budget. So Ive been reading about all types of sound proofing methods for the past 3 hours and I want some feedback from people who have actually tried this themselves. Ive read about building an insulated room inside of a room including a raised floor and second ceiling which seems to be the quietest method but, requires a bit more investment than Id like to put into this but, its not totally out as an option. Ive also read about layering cardboard, carpet, and acoustic tiles from the walls and ceiling which is cheaper but, Im unsure of the overall effect it would give. The appearance of the room would not really be too important to me but, I would like it to effect the structure of the room as little as possible since we do not plan to live here forever. I guess the main thing to figure out is how to drown out the bass really, the mid and high tones should be pretty easy. I also play bass and would like to be able to really crank the fucker up. Any feedback would be appreciated and I apologize for the long and likely hard to understand post.
