Is it possible to soundproof a wood fence?

I live near a busy road and want to block traffic sounds. Is there a product that will absorb or block the sound?

A solid wood fence (very little gaps between boards) is the standard way to reflect road noise. Is yours perhaps staggered face boards - one on your side, then next on other, etc - which lets air blow through, but also a lot of the noise gets through. Redoing it as a single-faced fence would reduce that a lot, if that is the case - shouldbe ableto reuse almost all boards ifthey are careful and use a wood block during removal rather than just hiting with a hammer - also easy DIY job and would probably get a better quality. Watch which way boards are turned to avoid streaks - keep same side "out", and check local regs on which side of fence has to be "out" - some cities mandate actual fence configuration, so check first.

In extreme cases I have seen wood fences back-sprayed with expanding foam then covered with a second layer of boards, then all stained so the foam looks like the boards, but that is real extreme and promotes fence rot and termite/carpenter ant invasion.

Obviously, if yours is a lattice fence, then there is a lot of space for noise to get through the holes, so you might need to reface with solid boards.

Other solutions - plant fast growing plants along the fenceline - things like ivy and clematis aren't the best for the fence as the rootlets grow into the wood so cut its life 25-50% but will block noise well and grow very fast, as will faster growing tall hedge plants and evergreens like dawn redwood, Stark willow, Thuja, and some cypress, hemlock, lilacs and junipers. Check with you local garden center, and also the local and state highway department engineering departments should have a list of the fast growing noise and view blocking plants they use along roadways.

Remember to check your state's invasive species list to stay away from them, don't make the mistake of using bamboo unless you wnt your entire yard taken over and your neighbors hating you, and watch overhead and underground utility interference.
