Have you ever heard of `teen bell or teen buzz?` It is buzzing sound that only teenagers can hear. Its sound is so annoying that pedestrians who hear this buzzing sound cannot help leaving. Originally, teen buzz was developed by a English security company. Its original purpose is driving teenagers away from shopping mall because teenagers used to hang around even though they have no money.
But, teen buzz gets its popularity at a wrong place. the place is a mobile phone`s ring sound market. Some people think that `if a mobile phone rings in a class, a teacher could not hear this ring sound.` It is starting point of teen buzz.
