Title: Best material choices to soundproof inside wood fence
Post by: Porchlight on January 19, 2018, 08:50:15 PM
Kind folks, please offer some of your wisdom on this:

I want to soundproof a wooden fence that has redwood pickets on both sides. We are extending it from 6' to 8' tall. The fence separates two small one-story homes.

Please recommend a few types of soundproofing material that:
1) will not mold, and
2) will do a good job muffling the sound of a female with a loud swooping "head tone voice" (think Julia Child 200-500 Hz) and a medium sized dog who barks a lot. (1500 Hz?) Road noise isn't an issue.

I currently have some carpet underlayment in there but my neighbor is worried it will mold once I put the pickets up on my side. (So far, no mold and it's been stapled up there for two years.) We live in SoCal, so no freezing temps, no snow. It rains a few times per year.

mass loaded vinyl and 1/2" cement board together.

No gaps any where.
Make sure the barrier hits the ground.

This is going to increase the fence weight by 5lbs sqft. so prepare the fence to support the added weight.

Your height will be what actually dictates reduction, this is known as diffracted path and shadow zone.
 So your fence might still not be high enough depending on distance from source to wall and from wall to receiver.

Since you are in socal you can see this up and down the I-5  go look how high the freeway noise abatement walls are.

Do the best you can, so that cost is justified by the reduction.
