Comparing Noise Restrictions

To assess how the new restrictions at Red Rocks Amphitheatre stack up in comparison to other venues, our volunteers have tried to collect information on similar outdoor concert locations. Although not all these data are exactly comparable (see below), here’s a general overview of the situation:



The decibel level and resulting effects depend on where the sound is measured. We were unable to obtain exact locations of measurements for most of these sites. Note that at Red Rocks and Fiddler’s Green, sound levels are measured at the front of house mix location, inside the venue. Most regulations (e.g., county and state limits) set levels at the receiving site, that is, your property boundary. Levels for Red Rocks are based on the assumption that sound levels will be 50 dB lower at the park boundary than they are in the Amphitheater itself.

However, the new restrictions place NO LIMIT on decibel level before midnight (or 1 AM weekends), and the end times cited above are not firm end times, but “curfews.” Beginning one half-hour after the curfew, penalties may be assessed for violations. Read the full restrictions here.

In comparison, at Fiddler’s Green:
All events are required to end at 10:45 pm, Mon-Thurs, and 11:00 pm Fri-Sun. with NO EXCEPTIONS. Official event time is kept on the Extech sound monitoring computer, and curfew is strictly enforced by the Tri-County Health Depart.
