Soundproofing with Eggcartons, miracle or myth?

As a former fireman I'll re-iterate what Hanydman said, this would be an accident waiting to happen from a fire safety standpoint, especially if you're talking about foam egg crates instead of the cardboard/fibre kind. Doubts? Take several out to the driveway (or other safe area) and fact check us on the flammability issue.

+1. This is how the Station Night Club fire started in Warwick, RI. (well that and the pyrotechnics inside the club.) The entire wall behind the bands was covered in the stuff.

actually I built my old singers studio, 2x6 walls interior walls were doubled batt insulation then 1/2" soundboard, and 1/2" drywall. It was pretty effective, understand though that A/C ducts, and gaps under doors will leak a fair amount of sound too, and windows also present a problem area... Interior rooms, which generally have no insulation in the walls are going to transmit sound as long as the walls can vibrate..
strategically placing some damping and bass traps in problem areas is the best bet.... I would check some home recording forums for some reading on the subject.
 
To add to this, what kind of cost would someone be looking at to do this? We just found out our jam room was being sold, they weren't making enough money, and now we have to move into the singer's garage. I haven't had a chance to check it out but it sounds like the garage is just a frame at this point. We were thinking of doing fiber egg crates on the corners to elminate the 90 degree angles of the walls and throwing up some carpet padding on the walls.

Sounds like we would actually need to hang drywall to finish the walls and then insulate and build second walls, floor, and ceiling. This sounds really expensive. Any other solutions on the cheap that would be effective to control outside volume?
 
One idea is a room within a room...

That's what I did. I built an elongated 10-sided room within a rectangular room.

Many studios are oddly shaped so that no two walls are parallel to each other and the ceiling is angled so that it's not parallel to the floor.

You can mount 'diffusers' on parallel walls. And yes, an angled (or sloped, in my studio) ceiling is good.
 
Making a room that sounds nice and making a room that doesn't leak too much sound are two very different processes. Start with the sound abatement. This is the time to do it, while the building is under construction. It'll be cheaper.

Rather than looking at us to reinvent the wheel, start with the acoustics101.com site I listed above. It has a lot of good information that Auralex admittedly put together as a sales device, but they also put it out there because they were answering the same questions over and over.

The increased cost to build in a little sound abatement now shouldn't be too significant.

This is an interesting article but the diagram shows a perfectly square room, which is another thing you would want to avoid if you were to build a room from the ground up. Reflections and standing waves are made worse with parallel walls. Many studios are oddly shaped so that no two walls are parallel to each other and the ceiling is angled so that it's not parallel to the floor.

This.

This stuff self-adheres.

As others have said, they provide sound dampening.

There are similar products, mostly automotive in nature. I built my (guitar) isolation cab with this product.

Hope it helps. FYI, for wave diffusion we use cloth wall-hangings, carpets, a couch, and big-ass pillows in our practice space/sorta studio. It works, and it makes things comfy. ;)
 
The best sound-DAMPENING on the cheap is old thick-pile carpets nailed to the walls and ceiling, and tall bookshelves full of books, magazines, newspaper, etc. You can position the bookshelves at angles to block specific reflections.

But in all seriousness, there is no such thing as sound-PROOFING on the cheap. Cheapest you can go is what was described earlier, a complete new set of walls and ceiling, with dead space between the outer and inner walls, and all the edges sealed so air does not leak between the two walls.
 
Total myth. Does not work AT ALL. The best result you can get with egg cartons is to make the room sound darker, with less reflection off the walls.

The myth is because acoustic panels inside studios used to have an egg-crate pattern to them; but egg crates are not acoustic panels, and acoustic panels are not soundproofing!

Turn down. Learn to play at a volume that won't drive the neighbors into calling the heat. Often the simplest solution is the least obvious.

Well, way back in 1975, when eggs were 25 cents a dozen and were packed in pressed paper (cardboard) containers, I spent most of an entire day completely covering all of the cinder block walls (including the inside of the large swinging doors) in my parents one car garage with them. They made a HUGE difference in the toneality of the room. Not completely anechoic but much better than before.

But it was far from soundproof. We were just as loud outside as before. But my parents said all of a sudden you could understand the vocals from inside the house.
:D

When I was about twenty the band I played with lived and practiced in a huge old house that we rented (cheap) from a buddy's uncle.

All I can figure is that he had a vendetta against his former neighbors and wanted to pay them back. :D


Anyhoo... We had three 4' x 8' sheets of 3/4" insulation styrofoam behind our drummer with the big grey egg-flats glued to them.

I don't think it helped much, but I remember being pretty PO'd when our drummer knocked a big dent in one of them.


One of our guitar players said: "it's okay man... you're the only one that will hear the difference..."


Smart-asses... they're often right and start young. :)
