Hi all!

I'm about to construct a vocal booth for my small 1-room studio, and hope you can help me out with a few tips...

My studio is a rather humble affair (especially when compared with some of the amazing stuff I see here) - One small adapted room, PC based, but yields decent results so far...

Now - I decided to build a small (1 by 2 meters) vocal booth, simply not to disturb neighbours late at night with loud singing. The point is not necessarily to archieve great booth acoustics, but to keep the sound from escaping the booth itself. It's a simple wooden construction, foam insulation on the inside.

And now my rather silly question - Given the booth itself (and the door, when closed) is sealed tight, and thus leaks almost no sound to the outside (and now you may laugh) : how do I prevent from uh.. suffocating in such a small closed space after a while?

That's overdoing it of course , but I do need a fresh air intake/outlet, I suppose...
I was planning on building a 'Z' type labyrinth construction for the in/outlets. Any tips you could give me concerning this issue?

Any suggestions would be greatly appreciated!

I bought one of these

at Home Depot a while back just to see how loud it was - it's actually pretty quiet -

I'd put the fan outside the booth at the bottom so it picks up cooler air, then duct up/over/down for the inlet - then, as far away as possible I'd do just the opposite for exhaust - using fiberglass duct liner (like Superduct) would cut noise quite a bit.

Putting the exhaust port near the top of the booth inside would remove the hotter air - it would also keep the fan noise from being as close to the mic. Putting the fan on the INLET will give a slight positive pressure to the booth, so that when you open the door any dust will EXIT rather than be sucked IN.

You want an Omega shape for each duct so you have more turns - when I can, I'll draw something to better illustrate... Steve

Sorry 'bout the side scrolling, long links or wide pix will do that - 'nother thing, you'd want to rubber isolate the fan from structure too. Plus, if you buy a larger one than you need, you could add an electronic speed control to slow the fan down, this will give quieter operation without limiting air flow as much...

A cheap speed control - wire the fan to this, slow it down til it's quiet enough -

(Just don't run your mic cables close to the fan/control/wires...
