GOYANG, May 31 (Korea Bizwire) — In a progressive move aimed at curbing juvenile delinquency and reducing crimes in public restrooms during late-night hours, the Goyang Police Station in Goyang, Gyeonggi Province has recently announced the installation of cutting-edge high-frequency sound speakers.
These advanced audio devices emit a discreet “beep” sound that is barely audible to adults but strategically targeted at the sensitive ears of teenagers.
Operating between the hours of 10 p.m. and 6 a.m., the newly installed high-frequency sound speakers play an ultrasonic tone with a frequency of 18,000 hertz (Hz), carefully designed to be perceptible only to teenagers.
Approximately ten minutes after entering the restroom, adolescents are subjected to this sonic deterrent, creating an environment that discourages prolonged loitering and fosters an inclination to vacate the premises.
“The human ability to perceive sound frequencies varies with age, and teenagers have the remarkable capacity to hear high frequencies, such as the 18,000 Hz emitted by our speakers,” explained a spokesperson from the Goyang Police Station.
“While some young adults in their early 20s may still discern these sounds, the majority of adults are unaffected.”
After an extensive eight-month pilot program, the Goyang Police Station observed a significant decline in delinquency reports involving juveniles, reporting an impressive 58 percent reduction.
Moreover, the overall crime rate experienced a remarkable 77 percent decrease, further highlighting the effectiveness of this innovative solution.
The implementation of these high-frequency sound speakers showcases the Goyang Police Station’s commitment to employing ingenious tactics to ensure public safety and combat delinquent behavior.
With this groundbreaking approach, the department aims to create an environment that dissuades misconduct, fostering a safer community for all residents.
As the program continues to yield promising results, it may serve as a blueprint for other law enforcement agencies seeking novel strategies to address similar challenges.
