After months of hammering out new noise ordinances and determining testing protocols and decibel thresholds, Grand County will hold a voluntary vehicle noise testing event near the entry booth for the Sand Flats Recreation Area on Thursday, May 27 from 9 a.m. to 11 a.m. Local law enforcement officers and policymakers will use this event to practice procedures and collect data. No citations will be issued, and participating vehicles will get free entry into Sand Flats. Both Grand County Sheriffâs deputies and Moab City Police Officers will use law enforcement grade sound metersâof which each agency now has twoâto conduct stationary sound checks on participating vehicles using a standard protocol that measures decibels at 20 inches from a vehicleâs tailpipe while the engine is revved to a specific RPM. Law enforcement officers will spend some training hours ahead of the event learning to use the equipment and follow the protocols; the event itself will serve as further training. Representatives from local ATV rental businesses will also be volunteering to help facilitate the event.
