Ahead of a Kygo concert a few days ago, Red Rocks Amphitheatre asked fans seated in rows 40 and above to consider bringing wired headphones to the show so that they could use an app to listen to concert “straight from the soundboard.” The request was met with a mixed reaction.

The request didn’t sit well with some fans, who soon launched an online petition to repeal what they claim is a problematic decibel limit at Red Rocks. Organizers of the petition believe the headphone request is another impact of the decibel ordinance and that the ordinance is “detrimental to the Red Rocks experience we all know and love.”

The petition reads: “This is unacceptable. People pay great sums not only on concert tickets themselves but on travel arrangements from the world round to attend these shows […] Now, Red Rocks, considered the greatest outdoor venue on planet earth, has its experience hampered by residents who move within 2 miles of the venue and complain about the noise.”

Exceeding the venue sound pressure limit of 108.0 dBA for a prolonged period of time could result in fines of up to $10,000 per occurrence, according to Westword.

The online petition has over 12,000 signatures already and continues to gain more.

While some were unhappy with the request, some concert-goers are suggesting people give Mixhalo a try. The free mobile app streams soundboard-quality audio directly to smartphones and headphones of concert-goers in real time. It’s also worth noting that the platform was co-founded by Mike Einziger, a member of popular rock band Incubus.
