What soundproofing products have the ability to contain the bass inside an untreated room so that a noticeable amount of bass that is escaping out of the room be significantly attenuated from the bass heard in an adjacent room?
I'm interested to know if there are soundproofing products to solve this acoustic problem and where I can buy them.
