I live on a little sidestreet next to a highway. The highway is raised (due to being on a steep hill directly behind our place) and has noise barriers installed.

By and large, highway traffic is a low, background static, somewhat like the ebb and flow of a more mechanical wind.

But, because our sidestreet skips a single traffic light on a parallel street, mororbikes live roaring through it, easily louder that anything from the literal highway. At this point, I'd support a ban on motorbikes over 80db.
