We back up to Belle Meade Circle which is the main street in and out of Piedmont, Woodbury, and Springdale.
We have a good size lawn at the back of the house that buffers us somewhat. The thing is the traffic is not heavy and in the evening practically non-existent.
My neighbors who back right up to the street do not find it a problem.
Like everything else you have to consider in buying a house, noise level is just another. I would be cautious about which street you back onto, and how close to the street the house sits.
