it really depends how you understand the meaning of the tag. If you would
map a "noise level" you would need normalized conditions to measure, but if
you just want to say "creates more / less noise than a normal asphalt road
around here" it could be possible. Yes, it might change what is considered
"normal". FWIW, when I rode on such asphalt I did notice a difference. And
so far they also tend to put signs there to make you aware of the "novelty"
(would obviously also change if it becomes the norm).

Cheers,
Martin
