I don't know but I would think not. In the 80s our Kraft R&D facility in Perlach, Bavaria was in a mixed housing & industrial zone.
The day time noise limit was 86dBa but at night it went to 74dBa ( a lot lower). The condensate traps on the cheese vats were a constant issue & I was in charge of the services so it took many attempts to kill the noise level.
