Question on foam..

[DaveDrummer]

I am planning on soundproofing my room with a roominator kit from Auralex. My question is: I know this will make the quality of sound in the room better, but how about outside? Will this help the sound from escaping the room as well? Thanks

Dave

No.
Acoustic treatment and sound isolation are two very different animals.

Maybe have a look here, and study up on the two subjects.
