Evening all,

I was looking to try and reduce the intrusion of road noise into the back
garden of my house. There is a 40mph B road directly behind the garden and
it can sometimes get quite busy. The noise is not a major issue in the
house (22m away) but it can make the garden feel less than peaceful.

I have seen a number of 'noise barriers' advertised from companies e.g.

http://www.jacksons-fencing.co.uk/pa...&fmc=BV&fnc=AX

I've not seen those designs before, but the common method seems to be a
three layer approach to try and destroy the level due to frequency changes,
see diagrams on

I've seen commerical ones in use in the UK, but don't know where they come
from. As the fence is close to the road a higher fence/wall of any
description is going to give the best result.
