Fascinating
This article on the front page of the Times is a fascinating look at cellphone rings pitched so high only children (and presumably dogs) and dogs can hear. The new signaling, to the youth, of the forbidden text. Strange, very strange indeed.

Just a point: There are no such things as "frequencies only a child can hear." True, most adults do not have perfect 20Hz-20KHz hearing, but some do (Me, for instance, and I'm almost 50 years old). In a room with twenty kids and ten adults, at least one of the adults will have the auditory acuity to hear the "for kids only" ring tone.
As you were.
At 38, I'm curious if I can still hear it!!
In my previous career, I programmed ringer tones for Philips. The high tones were the only one to come out of the Piezzo-element (buzzer) with enough volume to hear........
