Maybe you should spend a little more time researching the absorption coefficient of materials.
http://www.acousticsfirst.com/docs/egg.PDF
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.
Yes, they do absorb some frequencies, just not in a way that is appreciable to the human ear.
If you've been in a properly treated room, you'd understand the whole concept better and drop this silly egg carton issue.
I dare you to post your defense of egg cartons on a forum like recording.org's acoustics forum. There are people a lot more knowledgable than I who will provide painful detail as to why you're sadly uninformed.

You seem to be under the very wrong impression that I actually advocate using egg cartons for any kind of acoustical treatment.
Maybe you should go back re-read the whole thread again, this time, keep in mind that I have worked in NUMEROUS studios that have been properly treated, and have helped construct two different studios. John Sayers trusted my knowledge in this field enough to ask me to edit his acoustics guide which he sold to SAE.
You can take your acoustic forum at recording.org and stove it up your ass. Oh wait, your head it there. But maybe there is still room?
Egg cartons have a .80 coefficient between 600-800hz! I can tell you for CERTAINTY that there are MANY rooms where this is a very problematic frequency and absorbing almost all of that frequency would be a god send! Not only have I worked in studios, but have done live sound for far longer that I care to admit, and have mixed sound in every conceivable situation you can think of (including fucking bluegrass bands huddled around a AT 4033 when the stage was RIGHT underneath Interstate 5!!!).
So AGAIN, while far from the best material to treat walls with, it is FAR from "useless". In certain situations, it could be JUST what is needed. It could be a far cry better than your caveman brute force of over-absorption of using OC 703 everywhere!
I like you OC 703 guys, you think it solves most everything.

You should take me VERY seriously when it comes to audio. I know my shit.

Certainly it is possible. What do you really think the probability is that he needs this solution in a home studio ? (serious question)
Thanks.

Maybe 30-50%
I have been in egg carton rooms (who hasn't if you have been doing this crap for over 20 years!). I can say with certainty that they sound a LOT better than without the egg cartons!

Well, the issue is not so simple!
It is desirable to have some RT in a room! The trick is to BALANCE the RT time of all frequencies, with maybe having a bit of emphasis on a longer RT time for frequencies 4khz and above.
The modern day "fix-all" that everybody seems to want to spout off on "acoustical treatment" is to put up OC 703 EVERYWHERE to control bass.
Guess what guys, it also KILLS THE HIGHS! So, you already have a room that is probably unbalanced with more emphasis below 4khz and you make that ever WORSE by throwing shit up on the walls!
Somebody be fucking creative for once and start talking about Helmholtz Resonators targeted to the resonant frequency of the fucking room!

I got it now. You think egg cartons are useful in acoustic treatment, mentally retarded people are fun to taunt and we should take you very seriously.
Thanks for clarifying...

I have issues with LF standing waves in my room. I was considering bass traps, but an article in EQ commented that although bass traps help prevent transmission of low frequencies out of the room by absorbing some of them, this meant that more bass frequencies would actually be reflected back into the room. This wouldn't be a great result in my situation...if this is true?

Draw a picture of Humpty Dumpty falling off a wall, perhaps even a second one of him smashed (whatever inebriant you desire). Photocopy the drawing a couple of hundred times. Past the 2 pics side by side in all the areas that have sound problems.
Play some thing at the freq. isolated as a prob and make a measurement to see if lining the space with egg cartoons really make enough of a difference to have dragged this thread out for so long.

Application of the Helmholtz Resonator phenomenon will resonate the more you stick out your neck the more egg cartons you will need.

Yes, people like you ARE fun to taunt.
Oh I get it. Now I'm retarded.

That doesn't make much sense to me. It sounds like the EQ article is conflating soundproofing with acoustic treatment. Further, it stands to reason that bass traps, by converting sound energies into heat, would decrease transmission of bass frequencies back into the room.
My bass traps consist of 2 layers of 2" thick OC703 (which I understand Ford Van despises almost as much as he hates mentally retarded people) spread diagonally 4 feet across the corners of my room, extending up 10 feet. This has considerably tamed what was a significant problem of standing waves. BTW, I doubt it has any significant effect on soundproofing. I achieved that by building a stand-alone building of cinderblock and filling the cinderblock voids with sand.

I'd have to read the article to see exactly what it's saying, but what you describe makes no sense. Bass traps work exactly because they help break up and absorb room reflections.

I see. What grade are you in?
Sorry, I generalized your comment about over-reliance on OC703. That was wrong.
Your hatred of retarded people stands on its own, without a matching disdain for OC703.
