High-pitched sound intended to deter school vandalism
The Langley School District is installing a device at Douglas Park Community School that sends out a high frequency sound that can only be heard by young people.
The device, aptly named the Mosquito, cost $5,000 in the 2013-14 budget for purchase and installation.
People between the ages of 13 and 25 can hear the high-frequency sound.
“It is meant to deter vandalism,” said secretary-treasurer David Green, in response to the budget question from Trustee Megan Dykeman at the last school board meeting.
The device will be on at night.
There is also one at Dorothy Peacock Elementary.
The devices are commonly used at 24-hour convenience stores to deter youth from hanging around outside.
At one popular Langley store, French-language newscasts are played over speakers to deter people from hanging around outside.
