Acoustical consultant: Franklin City’s two Larson Davis meters likely insufficient; recommends site visit and mitigation study

An acoustical consultant told Franklin City officials that the city’s two Larson Davis sound level meters could be integrated into a broader monitoring system but are likely insufficient on their own and that a site visit during an event and a detailed noise‑control study are needed to identify effective mitigation.

The consultant said the first step would be to review the project specifications, visit the site while a loud event is occurring if possible, and collect additional monitoring data before recommending equipment or mitigation. “Two locations are most likely not sufficient,” the acoustical engineer said, adding that monitoring should focus on noise‑sensitive property lines and worst‑case receptor locations.
