MORRISON, Colo. (CBS4)– The noise level of some concerts at what many consider the best outdoor music venue, Red Rocks Amphitheatre, is being measured to see if it’s just too loud.

Homeowners living in Morrison near Red Rocks claim some concerts are not only too loud, but say some of the musical acts are literally shaking their homes.

“Starting two or three years ago they started really cranking up the volume and added this deep bass which is coming into our homes, even with the windows closed,” said Morrison resident Elizabeth Roth.

About 30 households are experiencing window rattling noise from certain concerts– especially EDM or Electronic Dance Music.

That group wrote a letter to Jefferson County saying they’ve had enough and want commissioners to step in.

“You’re lying in bed and it’s ‘Boom, boom, boom,'” said Roth.

In January, Red Rocks implemented new sound regulations and despite having had just one concert since then, residents say those changes are minimal.

Officials from Morrison, Jefferson County Commissioners and the City and County of Denver will visit some of those homes to find out what they are experiencing.

“I think if we get up there and we see there is a lot of noise, there is a problem. We will talk about what are the solutions,” said Jeffco Commissioner Casey Tighe.

The group is touring the area after 10 p.m. to see just how loud it gets at night even as the concert continues. Officials want to resolve the issue without taking away the character and experience that makes Red Rocks unique.

“I’m not going in with any preconceived notions, I just want to see what they’re experiencing and hear what’s going on,” said Tighe.

“If you go to the symphony, the theater, a sporting event, almost all of those things wrap up around 11 o’clock. The only thing that extends longer than that are night clubs. This is a park, not a night club,” said Roth.

More than 80 concerts are set to take the stage for the summer concert season. They must end by 12:30 a.m. on weeknights and 1:30 a.m. on weekends. The sound pressure limits have also been set as part of the new regulations.
