you need to subtract the interior wall space which for decent isolation will be about 8-9 inches. as Panamonk shows in his drawing, you need to build decoupled walls, ceilings, HVAC, cable conduits, doors, windows, and possibly flooring depending on your needs. generally speaking, using common...

design the control room based on master video edit suites so you have both the CR and the home theater in one :-) usually this involves having the floor staged so the mix position is at one level and viewer at the next level, but all within the 5.1 (or 20.2.2) field. as far as sizing, the full...

between other furniture, equipment, people, etc i think the desk material will be the least of the influence on your room. as long as its not vibrating or reflecting sound from your monitors into your mic, it shouldn't be a problem.

its going to sound like a small box... is there another alternative?

depends. if the insulation is for treatment, then compressing it will help but the rigid insulation will still be more effective. if its to dampen the walls internally, then don't compress it too much as you just want to dampen the panels and avoid resonances in the air cavity.

i would go with the high ceiling you can. 10 foot or 11 foot is good. 8 foot as a minimum. esp if you want to put in an acoustic tile ceiling you want the tall ceiling. this way you can build in any isolation you need and then put trapping overhead to preserve floor space. if you don"t need much...

what are the thick yellow block on the side? best bet is to make the corners of the room deep and wide where possible to get the most bass trapping. wall-ceiling/floor-wall/vertical corners work for bass trapping with tri-corners being the most effective spot (in most cases). then add a front...

looks like a nice space! i have to agree with fitz - adding the inside drywall probably cost you 10db of low frequency isolation. now if you have put the drywall between the studs, you could have gotten another 5-6db plus whatever you get from the inner room. in any event it is what it is... the...

car are actually easier than most other "rooms" for a simple reason: no (very little) bass is trapped! the bass leaves the vehicle and is gone... so modes in a car are mostly restricted to mid and higher frequencies where the density is high enough to smooth out the response... JBL has a number...

its possible - i'm assuming you're talking about rigid insulation panels hanging? :-)

ok... better late than never :-) this design uses several panels constructed of 5/8" drywall on 2x4 frames. they somewhat interlock with the base and top plates and use several carriage bolts per side to hold the walls together. the panels are isolated from the floor and ceiling with 1/8"...

i've seen numerous reviews around. Ethan has one on his Real Traps site. bottom line, it can almost correct things in a given space for a very small area in which it would be effective (i.e. move your head 1/2" and its gone). eTrap is another specialized tool but useful only for certain cases...

your going to need studs to support the mass... 2x4 w/ r13 and line the studs and joists w. felt strip and use a layer of 5/8" drywall on each side. make 4 panels - one w. door. pin hinge them together and large rubber seals on edges. lay on a top panel (like walls) for ceiling. 4'w x 5'd x 7'h...

check the GIK acoustics, RealTraps, and ReadyBag sites for examples of commonly used layout options for porous absorbers and diffusers. In general you want bass trapping in all the corners and absorbers at first reflection points on walls, ceiling, and back wall.

start with the bass traps in the corners. this will add the needed bass control and start the absorption on the high end. since you have parallel walls, you'll get some slap echo. not a problem. thinner absorption (2'x4'x2" hung midway on the wall between floor and ceiling) staggered on the...

as far as noise - its more likely to happen in congested areas where neighbors don't share your taste in music. and i've lived in towns in NJ where noise ordinances where enforced (extra money for the town government) - busting parties at the nearby campus, and a couple of times for local bands...

version 2 with the slope is better. less refraction. put the monitors on stands behind the console not on it.

except noise violations can be $1000 per incident so yea, you might consider your options regarding noise isolation... i'm just guessing $25K-30K based on how much it really costs to ultimately build a room which can house a 120db band and sound relatively OK... the materials for such as room...

interesting... here's some costs for recent clients: high isolation (~50db) - 600sqft, 3 rooms - $40K in materials (double wall, existing home structure), <$10K labor + DIY very high isolation (~60db) - 420sqft, 2 room - $30K in materials (double wall, existing home structure) + <$30K labor...
