How to Decouple Your Glasses to Create a Tone

The problem with decoupled walls is that that air gap because it's acting like a spring and because it can resonate. If it's not at the proper thickness for the air gap that resonant frequency may be within the range of sounds that you're going to generate either inside or outside the room. So what you would love like to do is make sure that your soundproofing technique was going to take care of those maybe mid to high range frequencies. And then make sure that the air gap would push would resonate at one of those frequencies so that the other elements of your soundproofed wall don't pass through.
