>>The only real solution is electric cars plus significantly reduced speed limits.
Which isn't a solution as it would be like saying "the only real solution is no automobile (cars/vehicles)", because people will want ever more speeds.
So I guess, we must look for other better solutions. Somewhere I read that some chemistry researchers (AFAIK at Purdue university) are trying to improve the road building material/tyre surface material such that the noise caused by the impact of tyres on the roads is reduced. They claim that the noise caused by the impact of the speeding tyres on the road-surface is a very large noise cause.
