I'd like to piggyback on this discussion.
I have a house that is near a pretty busy intersection. The fence needs to be replaced in the next year or two and when I do, I want to do something to reduce the traffic noise. The house has a great backyard except for the traffic noise. The inside of the house is fine with plenty of insulation and triple pane windows.
I can think of one of two solutions.
1) Double layered wooden fence with something such as http://www.acoustiblok.com/aco... in the middle
2) Brick, masonry, or concrete fence
The good thing is that the zoning laws say that I can put up an 8' tall fence without a permit.
Has anyone been in a similar situation? What did you do?
