Studio Ventilation

[Bobbsy]

The trick with ventilation for sound studios is to use very large cross section duct work (with multiple baffles inside to prevent sound getting in) and very slow moving air.

It sounds simple but getting it right is the work of specialist professionals.

So my usual solution at home is to run the air conditioning (which also provides heating) on high between takes and turn it off when actually recording.

I got lucky with A/C for my studio.

When I decided to install central air conditioning in the house...the main goal was the upstairs, which is where the heat was the worst, and downstairs it's pretty cool except maybe in the two hottest months.
So as they were running the ducts, I asked the guy if he could run one all the way down to the studio...and at first it seemed like it would not be possible, but I showed them how they could run it through an existing closed porch, through the floor, and then a hard L-turn into the studio.
Ended being a piece of cake, and due to the extra length of duct...you can't even hear the A/C noise or are rushing in.

I then wrapped heavy insulation around the duct, then boxed it off, and by the time I was down with trim-n-paint....you couldn't even tell there was an A/C duct in there.

So my studio has great A/C and I can run my gear even in the dead of summer, and it's very comfortable and quiet. I just leave my studio door open, and the A/C return upstairs pulls the hot air out at the one end and the duct serves cool air at the other.

I worry that I've made my booth so sound proof that it's also "airtight"?

How concerned should I be about fresh air (oxygen) getting into the room for the performer?

Does anyone have a similar experience?

(BTW The room does have it's own window AC unit that I built into the wall to cool the room in the summer. Some O2 may come in through it, I don't know yet.)

I'm afraid the first session I do in there, I'm going to turn around and see the drummers lips turn blue right before he passes out.

It might discourage time-wasting.

Get them into the studio, tell them they've got five minutes to get it right before their air runs out.

You should get a specialist!

Thank you for the advice Aan! I'll definately check out Mitsubishi too.
