What causes road noise?: Physics Today: Vol 62, No 12

Unfortunately, no. In fact, a flat road is a bad idea for many reasons. For one thing, the road would not be safe; absent texture, friction would be low and braking distance could be compromised. Even in terms of noise, engineers have learned that a perfectly flat road is not a quiet road. The reasons lie in the mechanics of the tire—pavement ...
