how to build a sound proof room?....?

Question

i've heard u can use mattresses, egg crates, etc. i dont want it to be too ghetto. i can afford to use maybe a few hundred dollars for materials....
it will be about half the size of a 2-car garage. (big enough for 2 turntables, 2 15" club speakers, with a little extra room for comfort)

I'm also researching this on the net, just curious as to what ya'll might advise....
Any suggestions would be great! Thank you! ;)

the whole garage is already insulated and has drywall up. i want the "room" to only take up half or less of the garage.

thank you all! yaaaaaaaay! i cant wait to start! ;)

Answer 1

Try insulating the walls. Any time you use it on inside walls it aids in noise control.

Answer 2

OK, so far every one here is on the right path. Let me give you some tips as to increase the effectiveness of your sound barriers.
-Elevate your speakers. Get those vibrationg monsters off the ground. Sound travels through vibrations, if you give it a solid foundation to travel trough, it will be close to impossible to dampin to acceptible levels. So, buy some rope and strong planter hooks or tool/ utility hooks and hang your speakers from the ceiling, this will eliminate the sound vibrating through the structure to the out side.
-Sound (vibrations) travels very well though ONLY a solid -walls- or ONLY a gas -air-. A great way to dampen the noise effective, is to force it through both solid and air, mutilple times. So the more 'foamy' a pruduct, the better it insulates noise. Styrifoam and eggcrate work great for this. Styrifoam is usually thicker than eggcrate, however, eggcrate has far more surface area, due to its wavey texture. So as to which one is better? Use them both if you can! With the wavey textured eggcrate side showing and the foam against the wall.
But get those speakers off the floor, and if you can, try to put some egg crate on the inside of you speakers leaving only the speaker cone free. This should result in a much more 'crisp' sound, less muffled by the bass. Do not glue it in there until you test run the speakers first. Too small of a speaker could result in a muffled sound. It works great though on larger speakers, try and staple it down in a few places first, then glue if it produced good sound.
Hope it helps.

Go to the store and get the foam mattress covers that look like egg crates. You can use cardboard to glue onto the back(the flat side, NOT the spiked side!) of the foam. Leave about an inch of a gap from the top of the cardboard and the top of the foam for over-lapping of the cardboard and foam together. Use either staples or thumb tacks to place the stuff onto your walls. The foam is a wonderful sound absorbing material as well as giving some additional insulation to the walls. Plus, the foam and the cardboard are cheap!

Answer 4

What you want to build is called an anachobic ( I think I spelled it right ) room. It is a very difficult feat to accomplish.
The egg crates are in the right direction but are of the wrong material. The mattress pads are, somewhat, the right material, but not thick or dense enough.
I've had quite a bit of experience with " garage bands " no offense. and have had pretty good luck with ready made, easy to get materials, that, will let you wail, far into the night
without pissing off the neighbors. E-mail me , if you like, and I'll be glad to turn you on to what I know, ( I promise I know quite a bit ) Have fun.

Answer 5

If you are putting turntabesl in there then I assume you dont want people outside like your neighbors to be bothered.

For that you want to use some heavy duty stuff to block the low frequency bass. Use drywall, granite board, etc. to line the walls. Anything heavy will do. screw those panaels into the existing studs.

Cover that with something soft like a carpet and then foam so that it wont sound like youre inside an oil drum.

Use a heavy door and Line the doorway with weatherstripping

Answer 6

My friend built a recording booth. He purchased some styrofoam tiles that were made just for that purpose. You want a rouch surface or obstruction on the walls and ceiling to reduce the soundwave's bouncing off them. You'll see this effect in many gymasiums.

Answer 7

here is a cheap way get some heavy quilts or blanket from a garage sale of consignment sale and line the walls with them pin them to the ceiling and where the mikes is going to be make a smaller room in close in the blankets believe me it works. you will have a near to profession sound.

Answer 8

for your walls put a layer of 20ml plastic,then alayer of insulation,then another layer of the same plastic.Dothe same on your celing and if you have a room under you ,dothe same for your floor.

Answer 9

the cheapest and very effective way is to use carpet padding and carpet the shaggier the better

good luck
