MORRISON, Colo. -- Red Rocks Amphitheater faced its first true test of the concert season since new sound rules went into effect on January 1, 2015.

Global Dub Fest, an electronic dance music concert, took over the venue on Friday night.

"It is a constant pounding of the bass," said Sherry Drobnitch, a Morrison resident who lives less than a mile from the amphitheater. "Sometimes the bass hits to the point where it's pounding against my house."

In order to reduce the sound level impacts on neighboring residents, bass levels must not exceed 123 decibels and noise must not exceed 108 decibels. Concerts on weeknights must end by 11:45 p.m. and by 12:30 a.m. on weekends.

"The key is trying to get that balance," said Casey Tighe, Jefferson County Commissioner. "We want to have a good show experience for the people going to Red Rocks, but they want to be good neighbors, too."

One infraction will cost a performer $10,000.

Performers at Global Dub Fest did not exceed noise levels on Friday night.
