Egg cartons on wall

Egg cartons did MUCH better than I thought they would in that test!

With the peak of absorption being between 500-800 (about 80% absorption!!!), I think they could be VERY helpful in controlling that troublesome PA feedback range during band rehearsals.
True enough.

But as for their use as "room deadeners" in studios by coating an entire wall with egg cartons, I don't think that even the authors of that test would consider anything close to that as a good idea. They do nothing to affect the room's bass modatlity, and that test only discusses absorption, not diffusion or reflection, especially in the high frequencies. Considering bass modality and HF reflection are the tuo biggest issues in home studio acoustic design, that test does nothing to address the usefulness of egg cartons in studio treatment.

Plus, what about the difference in material? In my area there are just as many, if not more, egg containers made from some form of styene as there are the old-fashoned pressed paper. I assume that test probably was on the pressed paper, and says nothing at all about the styrene ones.

If you want to use egg cartons, go for it. You only live once. Just put a really big "No Smoking" sign on the door of your studio.

There are plenty of other materials that can be had for pretty cheap that will do a much better job of treating your room than egg cartons.
 
Back when I was a teen (in a galaxy far far ago :)) we wanted to deaden our practice room so we completely covered all the walls and ceiling with regular corning owens 4" fibreglas and then covered that with sheets so the fibers wouldn't get all over us. It was pretty funny putting it up since we covered every inch of skin and ducttaped our sleeves etc. Even then we were itchy for days.
That room was the deadest thing I've ever been in ...... it was so dead that it was kinda weird to be in. I slept there one night and I could clearly hear my heartbeat because there was absolutely no other sound to mask it.
I feel pretty sure it would have sucked for recording although we never tried it.
But that was one dead-ass room!
:D

I actually covered all rooms and ceiling in foam in one of my misguided attempts to make "good" recordings. I know what you mean about how weird it seems to be in a completely dead room.

But the real question is "why" would anyone want a "dead" room ?
Bass traps are probably a good idea, but I am not sure there are really effective ones for "home recording" sized rooms. Maybe there are, I just don't know of them.

For practise/jamming sessions, I prefer a dead room. Otherwise all the live reflection going back and forth will kill my ears and make my head spin.

LOL, sounds like you've been where I've been! Glory days!:D:cool:
 
Egg cartons are useless for sound proofing or acoustic treatment.

I've used Owens Corning 703 fiberglass which works wonders. It is far better than the Auralex crap, which is only effective on high end dampening, leaving bass uncontrolled.

Here's a link to what I did: http://www.toddejones.com/hugegallery.html and http://www.toddejones.com/hugeconstruction.html

If trying every approaching that sucks first before finding a good method makes one an expert, then I am that guy.

My room sounds 927.3% better than when it was bared stucco'ed cinder block.
 
Egg cartons are pretty much transparent to sound waves.

Building simple, inexpensive bass traps actually can improve the sound of the room. Egg cartons can't.

Sorry.
 
Back in the 70's we used old matresses to line the walls of a garage. Lots of working putting them up & down for each jam/rehearsal but we thought we were doing the neighbours a favour if nought else.
I've seen lots of places with egg cartons on walls - it was almost the symbol for home recording on the early 80's - back when a 4 track cassette player and a Tandy mic made you a semi pro.
I've opted for bookshelves with real books (pre read books are better as the pages have more air between them - porn books aren't so good as they seem to loose integrity over time & reuse) & curtains as much as possible. I have an old, non functioning, piano at one end of my room that seems to be useful to break up the space & waves (I've had to put a cushion damper on the strings so that I don't much sympathetic vibration though).
I also have a few very heavy, very big cushions I stack, lean, move about as needed.
Apart from that I'm at the mercy of a small rectangular prism.
 
Actually, for acoustic treatment, it is FAR from "useless".

Sorry, I was a teenager too and went this route to absolutely no avail.

What happens is you invest so much time and energey collecting and installing the damn things, that when you're done, you've already convinced yourself they make a difference.

Further acoustics research has reinforced the uselessness of egg cartons. I challenge you to find an authoritative source that advocates egg cartons for acoustic treatments. All you'll find is anecdotal nonsense.

Insulation really isn't that expensive and yields actual results.

Fordvan: the authority on egg carton accoustics.

hahah

I think Ford Van just likes to argue semantics.

Technicaly yes, he's right..egg cartons do absorb/diffuse some frequencies. So does the light fixture on the wall. So does the wallpaper, picture frames...

Maybe you should spend a little more time researching the absorption coefficient of materials. :rolleyes:

I never said another adovates egg cartons for acoustic treatments. Neither do I. I argued that they were "useless". With an absorption coefficient of .40, they perform better than fucking drapes do! It is better than carpet too.

Egg cartons are actually about on par with peg board over fiberboard.

In fact, they rate about as good as PEOPLE do for absorption.

Check your facts and try to pull your head out of your ass and read what I ACTUALLY say before you try working on me newb. :mad:

And my last post applies you too ProFool boi.

awwww, shucks...thanks Ford Van boi! I thought you forgot about me. I so love when you mention me in your posts.

thanks for validating my post!
