Egg cartons vs soundproof foam

>>69970455
Egg crate foam is really cheap though.

Don't know about egg cartons themselves.

>>69970568
I've got at least 50 behind me.

Neither. Both of those are for recording purposes to reduce echo etc.

The only way to truly soundproof is to literally build another wall in front of the existing wall. Empty space blocks sound much better than material no matter what it is. However soundproofing material is essential in the process but is usually a vinyl type material usually less than a half inch thick and sometimes can actually be painted on.

I have spent so much time with this shit, believe me I wish I were wrong.

Also it depends which frequency. If it's bass then absolutely yes another wall needs to be built.

Don't waste your time, OP.

On 4chan?

>>69970981
both I guess

Egg cartons don't do shit. What is your application? Are you tying to deaden a room for a better monitor setup?

If you're trying to reduce sound coming from your room, look into hanging heavy blankets and mattress foam toppers

I'm just trying to keep a little bit more noise inside the room.

I'm only doing 1 area and it's invisible (under the desk)

Egg crate foam, they make it for mattresses.

Actual egg crates are cardboard and won't do shit.

No, it is a myth

what this guy said,
>>69970831

Acoustic treatment =/= soundproofing

the purpose of the foam or egg cartons would be to reduce the number of reflection points in the room
