My Basement Studio- ready to ask questions
Originally posted at johnlsayers.com, topic 11179.
Soundman- Thanks for the links, but I feel I might be miswording what I am saying. I have read all of those and use the tools constantly, but sometimes they just do not lead you to exactly what you are trying to do, ya know?
I know Rod has posted (several times) the code for fresh air in the US. I get the codes, which is why I am asking this question:
I have a central air unit with the fan outside of my basement. This distributes the air throughout the house. I plan on adding a duct to push the cold/hot air in and add a duct to pull the air out, like it is setup in for all the rooms in my house. That is not an issue for me.
My issue is the fresh air- Will the air that is being pushed and pulled via the ducts I will be adding from the existing ones be considered fresh air? The only reason I ask is because the central unit circulates the air from the inside, which would be partially fresh air due to every room having windows or doors for fresh air to get into.
If I cannot use this, I am guessing I would add a vent for fresh air to come from the outside and for air to go out, and use the baffle silencer that I have seen built on here a bunch of times.
My question- in short- will the added duct work from my central air unit be acceptable as fresh air?
Actually, those links were much more about your first question than your second question:
"1) how do I soundproof the inside of the duct that is going to the studio to pump air? I would assume the sound would travel right through the vent to the rest of the house, thus making isolation created rather pointless. "
They cover all of that pretty well: Lining your ducts and building silencers is the way to go. Lots of examples there.
I don't think those threads deal much with code. I think the only person who can determine if your fresh-air plan is good enough and meets code, is a qualified HVAC contractor. I would imagine that it depends on the maximum number of people you will have in your room at the same time, and the flow rate, and the amount of fresh air mixed into the system, and the total number of outlets, and a whole bunch of other things. I'd really suggest that you get an HVAC guy to look at your plans, and tell you.
Personally, for my room I'm planning to build a separate ventilation system, not connected to the house at all. The last thing I want is cooking smells getting into my studio from the kitchen, or the smell of popcorn from someone watching a movie, or even worse, cigarette smoke getting drawn in. Nobody in the family smokes, but guests sometimes do, and I'd really hate to have smoke in my room: So I'm building a separate system, for those reasons, but they might not apply to your situation. That's just I myself me personally!

Hi Everyone- major progress has happened. Framing, drywall, electricity, ventalation is done. I even finished the ceiling with the isomax clips, hat channel, double 5/8 drywall. The room is pretty echoy (The floor is still the cement), but I turned the radio on full, distorded blast just to test it out, and I must say I was pretty impressed. I muted the TV on the floor above and could hear a faint noise, and I think it was because I knew the radio was on. When the tv was at normal volume, which is where my girlfriend will be watching tv, you could not hear a thing!
My question is this- once I am finished painting and the floor is done, can I do anything to treat the room that will help with the soundproofing even more? Will traps or anything keep the sound in the room and make it even more quiet above?
