Here's a quite little update on my acoustic engineer's progress.
I don't have anything tangible just yet, but I did hear from Brian this week. He had some questions about A/C and ventillation. He thinks that my current plan of two 8" ducts, one incoming and one outgoing, tied into the house's system is good, provided that the ducts are of sufficient quality and make a couple of turns. The distance between room and A/C system is fairly short (thank goodness). He recommended round, non-flexible ducts. He said that the worst case scenario is that the ducts would need to be encased in drywall, which means a lot of framing in the attic to accommodate that. (That would suck.)
Good that I received the call (as opposed to my doing the calling), but not so good that I didn't get anything by week's end. However, I realize that my project is rather "small potatoes" compared to the "real jobs" they're working on these days, so I'm not disappointed.
Hopefully I'll have more useful stuff to add this week.
Unrelated to the project, it's been a great week otherwise. After driving the same car (a 1991 Mercury Capri XR2) for almost 12 years, I finally got the permission slip from my C.F.O. (i.e., spouse) to get the car I've loved since I first saw photos of it on the Internet almost two years ago. Then, the next day I received an invitation from Mike to see a show in which he performed. It was quite a distance away, but with a car that was screaming to be broken in, I graciously accepted his offer and brought a friend of mine along for the ride and show. I'll spare everyone the details -- I'll just say that we all had an awesome time!

keith,
i dunno about that car, man ... i can't see putting more than 5, 6 sheets of 5/8 drywall on that roof ...
by the way, i realize you're in probably good hands now, but you might be interested in doing a search on paul woodlock's thread (studiotips forum) for "splitter silencer" or just "silencer."
i don't know what others think about this strategy for soundproofing ductwork but i was seriously thinking about doing it. it makes a lot of sense to me intellectually and doesn't seem too hard to do.
it's basically big boxes of rockwool with the air going through (empty pathway, equal in cross section to your duct work cross section, reserved for the air to travel), the wool absorbs the sound. but no backpressure is added to the system. the rockwool is "to the side" of the air pathway.
this might be easier than surrounding all your ductwork in drywall. or maybe not. it really probably depends how long of a run we are talking about. the silencers DO have to be very long to absorb low frequencies.

Ha! Consider that this was the car I just sold yesterday -- pretty versitile, don't you think?Dan Fitzpatrick wrote:i dunno about that car, man ... i can't see putting more than 5, 6 sheets of 5/8 drywall on that roof ...![]()

There were six bags of concrete (2 in front, two in back, two in trunk), lots of heavy guage steel posts, and a bunch of redwood 2x4s for a fence project at the old house! (I relied on a friend's real pickup truck for the fence boards the following week!)
Oh, and I might as well show you the finished job too.
Don't worry, folks -- the new car will not be abused this way!
(Oh, by the way, for all you Aussies out there -- yes, indeed, that was the Australian-made 1991 Mercury Capri! Great car -- lasted many years!)

My old car (filled with lumber and stuff) which I sold two days ago? Or my new car?
