GoKawiilUniversal's noise-engineered roller coaster still draws neighbor complaints over rider screams
Universal Studios Hollywood spent three years and heavy engineering—pea gravel track fill, glass 'scream screens,' and a 940-foot sound wall—to minimize noise from a new 72-mph looping coaster near a residential area. The measures worked during rider-free tests, but once real passengers boarded, nearby residents reported constant, piercing screams every 30 seconds throughout operating hours. Universal is now adding more sound barriers and adjusting hours to address the ongoing complaints.
