In the News (from Reuters): “Park plays high-pitch tone to discourage vandals”
A Tokyo park has started playing a high-pitched tone at night that only young people can hear to help drive away teenagers who keep vandalizing the toilets and other facilities.
My comment: It is known that before the age of 20, a person can hear the higher frequencies of the audio-frequency range. However, without showing them the method for the correction of egoism, we are using what amounts to military tactics against our children!
