Music technology that is used to keep birds away from a bus station in North Carolina may soon be employed to keep away other "pests."

Officials at Trade Street Station in Charlotte, North Carolina, currently use the station's loudspeakers to emit the calls of hawks and owls to frighten away pigeons that roost in the rafters. Now, they plan to use the sound system to play classical music and smooth jazz to discourage loitering teenagers.

A spokeswoman told a local newspaper, "The idea is to make the atmosphere at the Trade Street station less pleasant for those who aren't there to catch a bus. We know if we play a certain genre, people won't want to hang around."
