Attach Anything To Money On Trim This EXPLAINED in 5 Minutes! 3 Principles of Noiseproofing (Cut Down Sound Through Walls!)

Sound was pouring through one of the walls in my shop. I decided to soundproof/noiseproof it a little better, and it seemed like a good opportunity to explain how some of these soundproofing concepts work!

There are really three methods for soundproofing rooms in construction:

1. DECOUPLING--This involves creating an air buffer between walls or materials. Sounds gets weakened as it passes in a wave through a wall. Forcing it to do this twice causes the sound to dissipate.

2. ADD MASS--Sound also has a harder time moving through denser materials. Adding two layers of 5/8" drywall one on top of the other, staggering the tape seams, is a great way to deaden sound in a room.

BUT, this works even better when you add a layer of DAMPING COMPOUND in between the drywall layers. When sound hits the first drywall layer, it flexes the soundproofing layer inside. This causes the soundproofing compound to stretch and shear the sound waves, TURNING THEM INTO HEAT!

3. ABSORPTION-- Some materials, like foam and insulation, are just good at absorbing noise and sound. Adding rockwool insulation, or even batts of fiberglass insulation, to wall interiors can help drastically cut down on sound transference.

I also added NOISEPROOFING SEALANT to the perimeter of my room, and the perimeter of my new drywall patch over the door. This sealant acts like a damping compound, shearing sound waves.

GREEN GLUE seems to be the industry leader in making soundproofing/noiseproofing compounds and sealants these days.
