Mosquito Ring Tones

The normal frequency range for human hearing is 20 hertz to 20,000 hertz. One of the things that happens as we get older, is that this range decreases. Here is a link to a New York Times article that has a chart showing by age groups the maximum frequency we can hear: http://www.nytimes.com/2006/06/12/technology/12ring.html?ex=1307764800&en=2a80d150770df0df&ei=5090&partner=rssuserland&emc=rss

Well, our ‘young’ students, ages 13 to 14, can hear in the upper ranges of 17,000 to 20,000 hertz. They can now select a menu and download ring tones for their cell phones which are preset to a specific frequency. This means that parents and teachers can’t hear them, but the students can. One such is called the ‘Mosquito Ring Tone’. Some of my 8th grade students already have it.

and see if you can hear a 17,000 hertz ring tone.

If you can hear it, you are young !!!
