Red pill me please

I've been reading "Understanding Audio" by Daniel M. Thompson.
In the chapter about room treatments, he says that the only way to really stop audio from leaving a room is to increase the thickness of the walls with the proper materials.

He goes on to say that "absorbtion materials" such as "acoustic foam tiles" won't do anything but change the sound characteristic inside of the room.


It just kind of struck me that every amateur pratice room is padded with foam or egg cartons because it "makes it sound proof".

Was that broscience all along? Was I tricked?

We were just misinformed back in the day. No, egg cartons, foam, even OC705 does little for 'sound proofing'. This needs to be distinguished between sound proof and room treatment.

Read the studio build and treatment forum here. Egg cartons no good for anything but making a fire hot. Foam good for spot treatment only after the issues of low end have been addressed in any given room.

Hinder of transmission of sound waves between rooms involves density of walls, and decoupling the structure from outer rooms if total (or close to it) is required. Yes, multiple layers of drywall (density) helps, but low end will be tough to stop unless the 'floating room built within a room' is constructed.
