Long and narrow: construction woes

[jingleheimer]

Background:
I guess my story starts off a little while ago when i started playing with a couple of friends who, before I came along were already recording. As for myself another friend and I had built a studio in his basement for personal use over the summer. Now since I have began playing with these fellows we have decided to construct a new practice space with recording capabilities. Which leads me to my questions.

Question:
1) What are some acoustice problems in long narrow spaces?
2) In picture Number 2 what would be the best way to cover these raffters
(and reduce sound spill)?
3) I know in the last "studio" I built acoustics were a little more of a problem
but should i worry about that in a practice "studio" where the sound will be
somwhat louder?
4) since this is not going to be permanent how would you construct walls
(picture 3) where the curtins are and (Picture 1 and in the layout where
near the "red poles")

I appologize that my questions kind of jumped around to several topics. But as always thanks for any help and support. -Jingleheimer-

Layout

I have drawn a plan of how i would setup the room. Broadband aborbers and bass traps made of 4"x1" wood, 2x 2'x4' 4" rigid fiberglass, and cloth material. These will be movable so you can put them in the vocal booth when recording vocals. You don't need them for practice purposes, but when it comes to recording, you will be better off having them. Above the mixing position i have shown clouds, these are just like the bass traps and broadband absorbers but i would suggest not having the wood. You will want you mixing position to be centre of one wall like shown in the plan.

hey thanks alot for the help we im going to show the other guy this stuff tommorow and hopefully get started building. Again thanks alot for the info! -Jingleheimer-

You shouldn't need the absorber at the curtain, just as long as the curtain has a lot of waves in it, it sould work quite well, and possibly put all those clothes you have in the vocal booth behind the curtain too. The rigid fiberglass usually comes in packs of 3 i think for $60, and you will need 18, so that it $360+wood and cloth. But it should be good for acoutics. Maybe, when mixing, take down the drums and put them out of the way.

Just had a thought for isolating drums while recording. It should reduce the volume of the drums a little which will make tracking a lot easier, and when mixing it works as a broadband absorber. Will need 8 more 2x4 4" rigid fiberglass, more wood, cloth, and MDF

Might wana put plasterboard up for a ceiling, to reduce noise to upstairs, and so you can get a seal around the isolation thing. To get the signal from the drums, you cud install cables above the plasterboard ceiling. Forgot to show in the picture for the isolation thing that you will need seals anywhere that air can get through.

Hey thanks again man the help is great! And in the second picture with the movable absorbers on hinges i love the idea. In fact that was one of my concers for tracking as to how i would be able to track our drumer(he likes to play with volume HAHA) but again thanks a ton for all the help. Hopefully when we complete it ill post some pictures to let you know how it went. -Jingleheimer-

Cool. I'm not sure how much that hinged panels will reduce the noise. If sealed well, it should be ok. What would be idea is, if they both went the full width of the room and were sealed, without touching each other, because the sound insulating involves a mass-air-mass structure. I just did the width of most, as building products usually come in 8'x4', and you said your room was 9'.
