Reducing sound in the Basement
« on: February 20, 2007, 02:25:15 PM »
I'm attempting to sound proof my cellar and turn it into a home theater. I have a lot of sound issues that need to be adressed. Just so you know, i'm not looking to completely sound proof, this is just a budget project.

1. The water heater makes a ton of noise, and i will be walling it off. Do i need a vent for the water heater to get enough air ( i think the wall will be about 4 or 5 feet away from the heater).

(A)If it's a gas heater, you may need a vent for combustion.

2. Theres a woodstove we use to heat the rest of the house. There are ducts that lead up to the floors above to utilize the heat. How can I reduce the noise traveling through the ducts?

(A) You would need to cover or line the ducting with closed cell foam.  Use the mat at the chart at

3. The footsteps above are an issue. Right now i only have about 7' of clearance on from floor to ceiling. I need the most cost efficient way to reduce sound.

(A)The cheapest way is to put MLV with foam backing under the carpet above.  Otherwise you'll have to float a ceiling using soundclips.  You can remove the ceiling and float another one using minmum space if you recess the clips up between the joists somehow.  See
