Soundproofing: Caulking the walls

See the previous topic in this sectionSee the next topic in this section

After reading "The Complete Guide to Finishing Walls & Ceilings, I decided to caulk under the bottom plate of all my walls. According to the book, it improves the STC (Sound Transmission Class) rating by 5 points. This equates to a 12% improvement when using a single layer of drywall over insulated (R13) walls.

Caulking the bottom plate of your framed-in walls is an easy way to keep sound in the basement.

This should help keep the sound from traveling under the walls, and also reduce the vibration of the walls when sound hits them. I spoke with a couple of DIYers who thought it was probably a waste of time, and that it wouldn't do any good. Nonetheless, I decided to give it a shot.

Acoustic caulk

Some parts of the bottom plate needed quite a bit of caulk to seal the gap in places where the board was bowed a bit. Other spots were tight and required very little caulk to seal. It took about 4 tubes of caulk and about an hour of my time to seal all the walls in the basement.

Not sure if I'd have noticed the difference, but I'm glad I went ahead and did it!
