Four Aspects of Sound Isolation
When it comes to sound isolation for your recording studio environment, you only need to keep four things in mind.
Mass: The first line of defense in soundproofing
Decoupling: Break the connections that sound vibrations use to get from one side of a wall to the other.
Distance: Gain better overall sound reduction and increased low frequency isolation.
Absorption: Control mid to high frequency and also damp the individual wall panels.
