This kind of policy does not accomplish the cost-shifting you talk about. Rather, a cost-shifting policy looks like: "in Maricopa county, a business may make as much noise as it likes, but must pay fees to the owner of any plot of land which has its ambient noise levels raised in the amount of $X per Y decibels per minute per square meter experiencing increased noise. "
I'm not aware of much regulation in the latter vein, at least not where I live. But it has the advantage of cost shifting, from ANY business, to those affected by the negative externality. That reinternalizes the cost without hampering freedom of businesses to operate in whatever way most efficiently accomplishes their goals, and helps C-suite execs see the true cost of their operations, which incentivizes them to innovate that cost away. It's also not specific to the cause of the noise, so church bells pay the same as the data center which pays the same as the glass factory which pays the same as the concert venue.
My $0.02 anyway.
