Yes. You can use Tapcon screws or power-actuated nails. Seal the bottom plates to the slab with sealant. Is this a rental unit where landlord will mind?

Do the walls need to be attached to the cement floor?
for a job well done....yes

if its a square box framed out well it should sit without being nailed down, you can fasten it to the floor joists above to help sturdy it if you dont want to nail into the cement.

nailing into the cement is going to help you keep good square and keep anything from moving, they sell concrete nails and you dont need many, if your decent with a good 21 oz framing hammer (or bigger) you can just pount them into the floor but it takes a bit of work. alternatly they sell a gun that will drive the nails for you but its expensive. you may be able to find a rental one somewhere but ultimatly a good heavy hammer is just as good.

also if you plan on this being up for a good while (more than 2 years) use pressure treated lumber against any cement surface. this is not a MUST but concrete holds moisture and regular kiln dried lumber will absorb the moisture and rot fairly fast, also keep your drywall about 1/4 of a inch from the concrete to avoid it taking on excess moisture

Rrog, I owe you an apology. Called my old drummer (who doubled up as our recording man/sound sound technician!) and he confirmed what you said. The egg boxes were more about the echo/reverb. Apparently they help to some extent with sound-proofing but not a lot. He went right into one about why we recorded one track in a church as is was the reverb that we needed.

Ok, I think I can handle this. Build the walls with drywall, and cover with panda. I can attach to existing walls and ceiling, hoping to avoid nailing into floor. still want to make some mufflers. I looked at the ones they sell on Ebay, can't I just buy a 2' pc. of 8" duct, glue a pc. of egg crate foam inside, and duct down the ends with 8-6" reducers, for a 6" line?

A product that is used in commercial sound proofing is rock wool. Roxsul is the brand name and is mfg. by saint gobain. It comes in batts just like other insulation. It is used to dampen the noises made by hvac units traveling through the ducts. It also is used around bathroom walls for the same purpose. I figure that if you are going to frame and drywall, that would definitely be a plus with your build.

Most people would not have half the class you display with a humble reply like that. Clearly you are a man who takes the high road. I tip my hat to you, sir.

Independent lab data shows that standard fiberglass works as well. This lab data is available online. Insulation improves things, but not as much as you'd expect. Stick to fiberglass since it's cheaper. Use kraft-paper faced R13.

That's a medium density insulation. Note the frequencies affected are 2000 and 4000Hz. Standard drywall at $9 a sheet will do a heck of a lot more.

If the noise you have is simply fans and blowers, a standard single stud wall will work with 5/8" drywall. You should frame at 24" OC studs, use the R13 I mentioned. You'll want to do the ceiling as well. By the foundation walls there will be a gap where the ceiling drywall does not contact the foundation, You will need to reinforce (block) this area with plywood, etc.

If you want to have a music system in there, that can be sound proofed as well, but with a modification to the aforementioned wall.

Thanks Rrog but we are all her to move forwards together. Being corrected when I was clearly wrong is surely a good thing. It's how we all learn. :hug:
 
One thing I did was build a housing for all of my inline fans, which are the loudest. I took 2 x 4's and built a box to fit each one, enclosed the sides with drywall, placed the fan in it, made the connections, then stuffed the entire box around the fans with insulation. I then closed it up, and used expanded foam to seal in the ducting. You can barely hear them run. There is little you can do for the Ac and the standing fans, but this will at least quiet the big loud ones. You can still hear my rooms run, but it isn't as loud as it should be LOL.
Would you happen to have a few photos of these fan housings? I think I understand how you built them but I'm a visual learner and not that great with construction. Thanks for posting a great idea. Peace.

Jimmy Page recorded the first Zeppelin in small rooms with an added single mic waaaaaaay outside. The Turk taught him that and he used it in ever recording - a distant dynamic mic. Added some latency and texture. Add some bounce I guess. It worked for Page & Company.
