Thumping bass from the Niteharts electronic music festival at Snapdragon Stadium rattled windows and kept kids awake across San Diego over the weekend, with residents reporting they could hear and feel the music as far away as La Mesa, North Park, Clairemont and Point Loma. The three-day event, whose headlining set paired Knock2 with DJ Snake, ran Friday through Sunday and left city officials explaining why they couldn't do much about it.
Niteharts featured a Knock2 b2b DJ Snake headlining set, with Porter Robinson and RL Grime among the acts, and ran at Snapdragon Stadium from October 9 through 11, according to The FADER, which said the festival was curated by San Diego artists ISOxo and Knock2, who also had opening sets. As reported by FOX 5 San Diego & KUSI News, dozens of San Diegans posted complaints on Nextdoor describing bass that was constant and vibrating throughout their homes despite closed windows and doors. One reader told the outlet the noise kept their child awake, while another said it negatively affected tens of thousands of nearby residents and thousands more miles away.
People called or emailed FOX 5/KUSI on Sunday to complain about the noise, and a petition circulating in Nextdoor comments urged bothered residents to report the disturbance to both local news stations and police, per the same report. Snapdragon Stadium sits in Mission Valley, close to homes and apartments, and this marked the third year the festival has taken place there, the station noted.
Noise Complaints Raise Questions About Oversight
Residents' complaints focused attention on noise from events at the stadium and how it is handled.
SDSU acquired the 166-acre Qualcomm Stadium site from the city in August 2020 for $86.2 million before opening the 35,000-seat, $310 million Snapdragon Stadium in September 2022 as part of its Mission Valley master plan, Hoodline previously reported on the campus buildout.
Sound complaints had surfaced before; CBS 8 reported that complaints arose in June 2023 during the multi-day Re:Set San Diego festival at Thrive Park, an adjacent outdoor lawn area where music wasn't contained by stadium walls.
Organizers Blame the Weather, Point to Fixes
Oak View Group, which handles marketing and public relations for Snapdragon Stadium, said in a Sunday email that it was aware of noise concerns and took steps throughout the weekend to address them, per FOX 5/KUSI's reporting. The company said Niteharts' performances were below the venue's 95-decibel sound limit and attributed the unusual sound travel into surrounding neighborhoods to atmospheric conditions tied to Tropical Storm Rachel, which brought cloudy skies, heavy rainfall and coastal flooding to San Diego County over the weekend.
Low-lying clouds can cause sound waves to bend and refract, making noise louder and allowing it to travel farther, per WRBL reporting cited in the FOX 5/KUSI account, and cooler weather with strong winds can compound the effect.
Oak View Group said it implemented additional sound mitigation after concerns were raised Friday evening, reducing low-frequency output, adding dedicated subwoofer limiters and applying system-wide sound limits. The company also lowered sound levels for the festival's final day, shortened its sound check by two and a half hours, and adjusted speaker output to reduce sound spill into surrounding neighborhoods, monitoring levels throughout the day. The final festival performance was scheduled to end at 10 p.m. Sunday, and Oak View Group said it held weekly meetings and distributed newsletters to neighbors with performance set times ahead of the festival, planning to evaluate sound data and community feedback to improve future outdoor events.
