I live a road which, as I have a school at one end, is busy at certain
tmes of the day. I have double glazing in the front of my house from a
small local firm and we noticed a huge difference in noise reduction
when we went from out rotten old wooden - 100 years old - to having
double glazing. You can certainly notice a difference when we open the
windows.

Most of that difference is probably down to the windows fitting better and
sealing out draughts - therefore noise as well - as the glazing itself.
