Sound expert urges measurable dB limits and meters to resolve noise disputes

The council heard a technical briefing on the village noise ordinance from sound expert Ralph Holddron, who recommended replacing discretionary enforcement with measurable decibel thresholds and calibrated meters to produce consistent outcomes for police and businesses.

Ralph told council members that subjective judgments by officers have produced inconsistent results — "one says it's not too loud, one says it is too loud" — and argued the solution is objective measurement. He recommended limiting weekday sound more tightly (for example, 80–85 dB Sunday–Thursday) while allowing higher levels on weekend nights with a clear cutoff time. He noted that lawn mowers commonly operate between 85–95 dB and highlighted that each increase of 6–10 dB roughly doubles perceived loudness.

To make enforcement less subjective, Ralph proposed that venues install or provide calibrated dB meters and that the village equip officers with meters read from a fixed receptor point (approximately 75–100 feet in front of speakers). "You want them about 75 ft in front of the speakers. That's going to be the loudest point," he said, and suggested meters could be mounted so officers could verify readings without leaving vehicles.

Council members and local venue representatives discussed permitting, special‑event conditions, and limits on low‑frequency subwoofers. A business representative offered to mount a dB meter on the building to demonstrate compliance during events. The council asked staff to consider how to integrate dB thresholds and meter requirements into permitting and enforcement procedures and whether to require venues hosting outdoor live music to install meters as a condition of their permit.

No ordinance changes were adopted at the meeting; council directed staff to review permit language and technical specifications for meters before the next meeting.
