I came across an interesting article in the New York Times technology section today. Students are downloading a high frequency ring tone to their cell phones that many "older" adults cannot hear! The pitch of the ring tone is about 17 kiloherz, and as we age we tend to lose that spectrum of sound first.
In my informal survey here at work, a 19 year old, 30 year old, and I (46) could hear the ring tone. Another 40-something and a 50-something could not!
Many schools require students to turn their cell phones off during classes. Leave it to our ingenious youth to figure out a way to get around that rule! They may not be able to speak on their cell phone without being noticed, but they can probably text message surreptitiously enough.
Click on the embedded player below to hear (or not) the ring tone for yourself.
