Why are US hwy so noisy???

ACC-HE

Have you noticed the hwy in the US are much more noisy than ours?

I like those shiny reflector stones, I think we should have those as well since the road visibility in the rain is not very good, but wouldn't they interfere with snow plows?

Concrete vs Asphalt, which one is the more expensive one?

and... would tires help reducing road noise of US hwy?
