freeway noise, but i want to enjoy my back yard too.
« on: May 30, 2014, 04:46:09 AM »
I bought my home 2 months ago. It is about 500 ft from a busy freeway in a well maintained, older subdivision. I was suspicious of potential freeway noise so I visited the property a few times before making the offer. Each time it was wet or damp in winter. I did not realize how much the moist air dampened the freeway noise. I am now the unhappy owner of a place in which I cannot enjoy my backyard. And I have to close the house at night to sleep...I hate it. I like the outside air..spare me the traffic and diesel.

All the posts I have read refer to being INSIDE to escape the noise. That is a prison. I want to be outside.

I am looking for comments from others who may have experienced this. I have done some research and learned that certain trees may help. but also read a government site that said natural vegetation will not work unless it is very dense and 100 ft deep....Um. I live in suburbia...I have about 15 ft max to work with. I am thinking of a solid row of Arborvitae. But again, the gov site was not encouraging unless I have 100 ft.

The yard is at 55 or so dB. I can't live this way and may just pack it up.

Any ideas?

Well the gov site you read is correct when saying that vegetation does very little or nothing for blocking noise unless it is super dense.
The only true weapon for outside noise abatement is to block and reflect sound away.
You will need to build a noise abatement wall, the wall must be high enough and long enough to eliminate line of sight. If you can see the road you can hear it. Now here is the tricky part, you have what is known as the shadow zone, this is the area behind the wall that experiences a reduction once out of the shadow zone the wall will essentially disappear. Look at it like the ocean..if we have a sea wall that is 10' and a wave comes in at 9' the wall pushes the wave back, but if the wave is 20' then 10' of the wave comes over...where the crest lands is the end of the quiet zone.
Make sense?
