I'm not familiar with noise as a speed consideration by my State DOT. Do you have a reference to the noise consideration for speed limits in the law/rule for your locale?

https://www.dot.state.mn.us/environment/noise/pdf/metro-nois... page 6: Minnesota classes some speed limit reductions as noise abatement.

Washington refers to modifying speed limits with the goal of noise abatement: https://wsdot.wa.gov/sites/default/files/2021-10/ENV-ANE-Noi... page 20

Delaware includes modifying speed limits (classed as traffic management) for noise abatement: https://deldot.gov/Programs/highway_noise/index.shtml

as a counterexample, https://wisconsindot.gov/dtsdManuals/traffic-ops/manuals-and... various pages: Wisconsin forbids using speed limit reductions as noise abatement.

Wow, noise measurements seem prone to manipulation. I am familiar with a State that measures actual travel speeds, throws out lows and highs, takes some %, and that is the speed limit ( <= max by law ).
