Common sense works!

Yea DD, I see your point, and I agree. A picture is worth....you know! That helped, and
I fully agree with the resiliant channel in regards to the metal skin. It should help vibration from transferring to the framing/skin. I might even put some diaganal stiffeners, maybe wood or even steel studs, between the steel framing,with some kind of neoprene or doublesided weatherstripping tape, to dampen the vibration, especially with bass amps, drums. But I'm no expert. Heck, I' don't even qualify as novice when it comes to this stuff, but common sence goes a long way:D Anyway its a start. And BTW, thanks for taking the time to illustrate what your doing. I think I'm going to load corel tomorrow and try it. Looks good here. CAD reduced to a bitmap or .gif kind of sucks. Although I just say where theres a new acrobat that reads CAD. Gotta check into that. Well, I just heard today my offer was accepted for the commercial building/home in Oregon. Got a month to get my house ready to sell and move...ah :eek: :eek: :eek: :eek: crap I better get busy...you too!!! Have fun, and may you enjoy the fruits of your labor soon:eek:

Yeah I had read that too about resilient channel. Still I can't help but think it would have some benefit using it on my exterior wall. I want to keep as much vibration from the outside metal siding as possible. Someone correct me on this if I'm wrong. I'm not worried about sound getting in but I don't want the metal siding oscillating at it's resonant frequency. Learned a little bit about that as a Sonar technician in the Navy.

Sonar tech, huh? Then you very might know quite a bit about resonances in metal sheets and how to solve the problem.

Triangulation, and attaching the sheet metal to such triangulations.

Race cars have the same issue, though the LF that causes the sheet metal oscillations is not due to sonar or subwoofers, but rather LF generated from tire, road and powertrain vibrations.
 
That's why everything on a submarine is shock/rubber mounted. The frequency of a poorly mounted ventilation fan could be detected outside the sub if the resonant frequency of some part of the outside hull was the same as the source (the fan). You might not "hear" it but it could be detected.

You end up with three options.
A. Isolate the source (rubber mounts, iso room, etc)
B. Block or channel the source away from potential resonant materials.
C. Dampen the potential resonant material.

One company I've seen has a material that adheres to the backside of your sheetrock. Their slant is that since sheetrock is "suspended" between studs, this suspended portion will resonate. Kinda like when you tap on the wall to find a stud. They adhere a dense material to the backside changing the resonant frequency. I got a sample from them a month or so ago but haven't really looked into it yet.

Mr. Sayers SAE site

DD, say, last night I looked at the SAE site, and unless I'm wrong, it looks like it has been updated, or I somehow missed a bunch of stuff. Take a look at how he designs built in the wall acoustic absorbers, and slotted absorbers. Looks like to me, theres a way to reverse your wall construction in different places and it might do the same STC
transmission loss, as well as build in your absorbers, with out loosing any floor space. Ill take a look again and draw a section. Like I said, I'm not even a novice, but I saw that last night and it finally sunk in. I think some of these ideas will work for you, and might even save money in the long run. But you would really have to analyse it, finance wise. I don't know. But its worth looking at. Same with the clips. Also, a few years ago,I was in a large garage studio, with linoleum or tiles(cheap) about 2 ft. wide around the perimeter of the room, and painted the rest of the floor. Then he put down some different thriftstore throwrugs around the painted area, leaving about a foot in betweem the rugs which was painted conctrete. WoW! what a sound. He told me about an edge reaction between the rugs and concrete to reflected sound. Acted like a diffuser, on the floor. The sound was fantastic. About .5 second reverb, but diffused. He had a few bass trap panels that were like gobos/dividers for amps. But they were hinged at the wall, and 8' high by about 6' wide. Like a wall, but trifold. They worked great, even as a vocal booth. Oh well, I'm ramblin again. Can't help myself when I see people doin projects like yours. Have a good one DD.

Fitz,
I haven't been to John's site lately. I'll look over there and see what's going on.

Just got back from a weekend at the beach about 2 hours ago. Can you tell I would have rather been here drawing my studio?:D

At least I caught up on some reading (NEC Electrical Code). Very dry but I picked up a couple of tidbits having to do with my wiring.
