In Sweden, teenagers hang out at night, especially in the parking garage, which causes a lot of riots and chaos at night at times, as well as constantly disturbing the neighbours.
To reduce this phenomenon, the city of “Skelleftea” in the Västerbotten county in central eastern Sweden resorted to a method called “hidden vocal intimidation”.
The town of Medina agreed with a specialized company to do this task, as the company will install devices in invisible places and emit a frightening sound at certain frequencies in order to spread terror in the teens loitering to push them to leave and return to their homes.
Swedish media, which published the news on Sunday, says that all attempts by the city’s municipality to persuade young teenagers not to hang out late outside, and in the parking garage, failed, as the municipality resorted to lowering the temperatures in the garage and reducing the number of electrical connections so that it is difficult to Young people have to charge their cell phones, which may prompt them to leave.
It is noteworthy that municipalities on the outskirts of the capital Stockholm have previously used such a device, but this method was met with great criticism from some residents, as the sound causes them to disturb them.
Also, the acoustic intimidation device was used in several European countries, such as Britain, with the aim of eliminating the phenomenon of teenagers writing on walls and vandalism at night.
