A teacher of mine has several clippings from the local paper in his room. I'm not sure how old this clipping was or what paper it was from, but it claims that:
According to the US Census, noise is the most frequent complaint of urban Americans. Nearly half of us live in areas that are deemed to be acoustically unsafe by our government.
— Louis Holger, M.D. from Oakland, CA in "Noise Unhealthy" about Concord CA's noise ordnance
I interpret "us" to mean Americans because the paper is from a largely suburban area with little noise pollution and the fact that it was preceded by a statement about Americans as a whole.
First of all, does the US even have standards of "acoustic safety"?
Secondly, is there any source for the titular claim?
