Sound levels were not so sublime for some Redmond residents last weekend during a pair of concerts at Marymoor Park.

Logan Harris, spokesman for King County Parks, said parks staff — using a Goldline Sound level meter during the Sublime with Rome shows — took 16 high-end readings on Saturday night. The average level was 100, which was 11 percent higher than the agreed-upon maximum of 90.

On Sunday, staff took 11 high-end and low-end readings: The average of high-end sound readings was 97, which was 8 percent above 90; the average of low-end readings was 115, which was 28 percent above 90.

“Occasional spikes of over 105 are acceptable, but these readings were consistently over,”  said Harris, noting that the sound-booth person was told not to take low-end readings on Saturday.

“The music’s level was completely unacceptable. Household windows shook during the whole concert,” said Mayor John Marchione in a press release. “The county needs to take responsibility for its events.”

Marchione sent a letter to King County Executive Dow Constantine and Sheriff John Urquhart, noting that “Marymoor Park needs to act like a good neighbor and turn down the volume.”

According to the release, residents who called the King County 911 dispatch reported that they were told to contact the Redmond City Council, which doesn’t have jurisdiction over Marymoor Park. Lisa Rhodes, City of Redmond communications manager, said they received six complaints via email to the mayor, City Council and the information line, and the Redmond Police Department had 14 complaint calls (five on Saturday and nine on Sunday) logged into its dispatch records.

Harris added that the sound policy was developed in collaboration with the City of Redmond police and King County. Curfew for concerts is 10 p.m.

King County takes readings from 345 feet from the stage and calculates them with a formula to estimate what the readings would be at 100 feet, Harris said. The levels are estimates, as there are environmental conditions that can affect the readings. Concert promoter AEG Live also has digital reading equipment in its mixing station at 100 feet.

AEG Live issued the following statement regarding the weekend’s concerts, “AEG is committed to working with the City of Redmond and all of the neighbors to finding ways to mitigate the sound concerns.”

Kevin Brown, King County Parks director, added: “Right away, we want to apologize to our Marymoor Park neighbors for the higher noise levels coming from the Sublime with Rome concerts Aug. 29 and 30. We immediately alerted AEG to the excessive noise and were informed steps were taken to reduce noise levels.

“Overall, we have received very few complaints about concert volumes this year. While we believe the recent concerts were an anomaly, King County Parks will work with the community and evaluate potential changes that would improve the process.”

Brown said they take the complaints seriously, since they work hard to be a good neighbor and ensure that the concert series is an enjoyable experience and a boon to the local economy.
