Here in Tucson, I don't need an extended session. During the hot months (pretty much the whole year except for our month-and-a-half winter) I get rid of the shirt as I walk into the booth. I'm hoping to actually figure out how to get an HVAC vent in the room in the next month or two -- before it gets too hot to do any sort of physical work in that room.

I have studied this subject since my radio days... and that was an era when the accepted understanding of acoustics was not as far developed as the crowd today that designs (and tunes) performance halls and houses of worship.
But from the old days, I have kept this logic in my collection: Take the volume of your room and multiply that by the number of "turns" per hour you want. You probably want to pump enough air into the room to "exchange" the contents 6 times per hour or maybe a bit more. New you know how many cubic feet of air per hour you want to move. Convert that to how many cubic feet PER MINUTE. You want a duct large enough that it speed, the VELOCITY in the duct does not exceed something close to 100 feet per minute.. Then you want the length of the well insulated (on the INSIDE of the duct for sound absorptions) cuct to be at least ten times the diameter. (Some amateur in the HVAC world suggested that ration. Maybe 20 to one would be even better.. We're trying to make the duct long enough that it becomes a muffler for the HVAC fan and for noises entering other ducts to other rooms.. Then you want an EXIT DUCT (return air) that is of equal size and length to keep noise from leading back in from that direction.
Have fun. Most HVAC folks seem to think that 1,000 to 1,500 feet per minute is an acceptable air flow in the duct system I'm not the patient, just the spouse staying on the lumpy little day-bed they provide, but I have spent the last two nights in a hospital room. Their DUCT VELOCITY is somewhere close to LIFT-OFF conditions at Cape Canaveral!!!  Maybe I should slip my little portable recorder in their tonight and make an audition just for laughs. |

Wow, thanks vkuehn! I'll try to figure that all out -- although, in this case, I think the primary considerations are, "Can I tie into that duct?" and, "Can I cut through that wall?" Essentially, I think I only have one choice for location, and probably very limited choices for size. But we'll see!

Once you have the hard part figured out (cutting and tie-ing in to a duct or two, remember to use baffles in the section of ducting nearest the booth. Also prepare a return air or out-going air duct as well (with baffles).
The out-going duct should be at least six foot or longer. Just sayin'

ME! ME! ME! ME! ME! The booth is in the barn and I keep the main part heated to 50 degrees F unless I'm teaching yoga in there that day then I pump it up to a whopping 60. I put the space heater in the booth to warm it, as you said then turn it off, and I also use that same heater on the yoga floor all during practice. It hasn't gotten terribly cold here in Maine yet, though, so I haven't had to do it everyday. |
The small heated carpets (or even throwing a blanket or thin rug over a heated blanket) work wonders, especially when in slippers. Nice and quiet, and if your feet and legs are warm, the rest of your body is fine. Cooler booth generally = less noise. |

Funny I see this thread tonight... just back from two weeks in Arizona and California deserts - we went there hoping to be warmer, but took the cold with us; now that we've returned to Indiana, the desert is back up in the seventies and it was 17 when we stepped off the plane in Indy. Uggh.
Back in my basement studio/office now, it's warmer in here than the outside the house, but only very slightly. A couple years ago, when I converted this room for its present purpose, the easiest way to kill the noise was to block all the paths for air in the ceiling and such. That was a mistake for both summer and winter. Fortunately, I have no moving computer parts in here. In the summer, that's good. In the winter, it means I have to rely on incandescent bulbs for heat (which I do like better than nasty fluorescent light).
Once in a while, I manage to buy and sneak in a space heater for my room here, and it's always promptly stolen for use upstairs, and I never see it again.
I'm cursed, that's all.
At least it's quiet.
