[s-cars] Garage project (NAC)

[djdawson2 at aol.com]

It is a 25 x 40 room, with a 12 foot ceiling.  I'd say every bit of it is a reflective surface.  That amounts to 3560 square feet.  Covering 50% is not an option.  I'm hoping some "apprpriately" placed items will do the trick.

Matress foam is a good fire retardant sound dampening material. Used foam
attress is the cheapest source for it. There's always some for sale in
ocal papers.
Beside, you don't need to cover the full area. Check what seems to be the
ost reflective surfaces (empty walls, ceiling) and cover 50% of the area.
t should be enough since you don't need a anechoic chamber.
Another solution is to paint a thick layer of tar, like the waterproofing
aterial for roofs, but the smell in hot days may not be that agreable.

hanks for all the suggestions.? I'm thinking the foam panel idea may be the
asiest.? Yeah, I know the fire issue, but I believe some of the insulating
oards are retardant.? I figure a couple of 2' x 4' sections up near the top
f the walls, and a couple on the ceiling should hopefully do it.

The space is not huge (25 x 40 x 12), but the best I could excavate into the
ountain behind my house.? Numerous larger tools (tire changer, balancer,
ool box, lift, press) will be going in as well, and should also help reduce
eflection.
Tom, to your envy.... this has been a long time coming, and nearly 2 years
o complete (don't ask).? I've dreamed of a workspace like this since I was
n high school.? Nothing about building a garage like this makes any
inancial sense... but as the years go by, laying under a car on your back
n the cold loses it luster.??Cars are?my favorite hobby, and that's how I
ationalize it to myself!!!

Dave,?

 am so envious of this project. I would give up half the house for such a
arage/workshop. Three or four bays and a recreation/ library and bath above
ould eliminate most of the need to?
isit the house. :-)?

orry, I don't have any specific positive recommendations for the noise. If
t is attached to the house, there may be paths to carry it inside as well.
 caution you about trying to use ordinary?
oam or other similar materials since most do not meet fire code if left
xposed. I expect the interior is somewhat empty when showing it off,
specially the new floor, which provides a lot?
ore flat reflective surfaces. A few of the cushion mats for extended
tanding and other equipment and vehicles can help interrupt the sound paths
hen the garage is in full operation.?

here are professionals that do sound analysis for public space design, but
ou can probably get what you need by just observing the layout of service
enters you regularly visit, and add?
 stop at a few more just to look and listen. You quickly pick up which ones
ontrol noise best just holding a short conversation in them, and probably
ee why.?

t may be that the dirt or Kaolin clay (kitty litter) is a great sound
bsorber :-) and a full shop is less noisy than an empty one. :-)?

om?
