Where can I get free egg carton foam?

Restaurants perhaps? Ask a local business if they can save em up for you. Most places won't want to leave stuff like that around, so it's best to ask, then stop off everyday to pick up the trash.

if you're looking to work on the accustics of the room, you'll need real acustic foam

[nooneimportant77]

well yes it will. but for true acustic work you'll need reall stuff, its alot more dense,

however just about anything will really work i dont know why i said that like that before, i made a vocal booth out of heavy blankets over boom mic stands for walls and it worked out fine.

The blanket idea is a good temp solution. Be sure to keep the blankets off the wall. You need the air space behind the blanket to deaden the sound. If the blanket is just hung down on the face of the wall the sound waves will travel through it and reflect off the hard wall surface, but if there is a foot or so of air space then the sound has to travel through the blanket, reflect off the wall, and then get back through the blanket again. By this time it should be knocked down at least 10 or more dB.

You can make some cheap stands from PVC pipe and save you Boom mic and lighting stands for other work, or build a quick stand out of some 1x2 lumber.

Try a local grocery store, or restaurant, like a Waffle House or an IHOP, they use lots of eggs.

But no, you don't need better foam, that stuff works great, Dave Grohl from Foo Fighters made his own sound studio using that stuff and it sounds amazing.

He said a lot of their recording was done in the shitty room he improperly acoustically secured himself.


So no, it works, your mic matters a lot more than the acoustics of the room.

It's a long shot, but try the free section on craigslist

the convolutions of true acoustical foam are meant to be anechoic (scattering the sound waves) while coupled with the absorptive qualities of the foam. the (usually) grey eggcrate foam you are referring to, by the nature of its open-cell structure, is ineffectual for either task. trust me when i say that i learned this the hard way after wasting money on cheap eggcrate foam and figuring out that it does little. so if you really want to cut echo, you either have to absorb the sound (dense materials) and/or trap it (anechoic dispersion).
that said, the cheapest i have ever seen eggcrate foam go for is $60US per 4" (1.3m) by 8" (2.6m) sheet. and as far as it being used for shipping material goes, i'm sad to say that it is seldom used with any frequency by any industry.

yeah the three temp. walls were basicly in the middle of the room and the fourth wall was a wall that has accoustic foam on it so it was fine.

and the three walls were all at different angles
