I notice this a lot, where there will be a couple miles of a blocked lane, but then only see work being done in a small area. Is it s...

does the human body have the ability to dampen incoming sound on command?
It seems that an unexpected loud noise hurts your ears more than an expected loud noise. Is this because you have the ability to dampen the incoming noise? Or is it the mental awareness of expecting the incoming sound that seems to dampen it?
