The Birth of "The Mosquito" Ring Tone
Invention of "The Mosquito" Ringtone is generally credited to the British inventor Howard Stapleton on a product he invented back in 2005. The product, "The Mosquito", had quite a different intended use then a "teen only" ring tone. In fact, the British inventor who came up with the ingenious idea, had intended to use the 17KHz tone to annoy teenagers and keep them from loitering outside of stores at night. The idea was simple, the device is supposed to annoy teenagers through the broadcast of a high level sonic frequency that works much like a dog whistle except targeted toward younger humans(namely teenagers). Since most money spending adults can not hear these high frequency ranges, the device leaves the regular paying customers unaffected. The product was sold as an ultrasonic "teenager repellent" which rides on the marketing of the well known product type that is meant for dogs. The product blasts a continuous 17KHz sound wave aimed towards dispersing loitering teenagers from the store at night. Since most adult can not hear the sound, the device leaves the paying customers unaffected.
"The Mosquito", as it was named, took advantage of a unique medical condition that most adults (and kids) are unaware of. The natural hearing loss for human adults tends to be particularly acute towards the higher frequency ranges and the condition(Presbycusis), gets worse as people gets older. Presbycusis is a natural biological condition that hearing medical professionals refer to as aging ear. Scientists have concluded that high frequency hearing loss generally start at around age 20. The human ear begins to lose its "agility" as we get older and become less capable of hearing tones in the highest human audible frequencies ranges (18-22 KHz). This condition gets worse the older you get much like most human bodily functions. Adults over 40 or 50 generally exhibit some extent of this condition, but young adults rarely exhibit symptom since most human communication occurs in the 200 and 8,000 hertz range. The deterioration of ultra high frequency hearing generally goes undetected for young adults because those frequency ranges are practically unused by humans.

The actual "person" responsible for the birth of "The mosquito ringtone" or as it was appropriately named the "teen buzz" by the teens that started using it is unknown. The best information narrows the birth of its use as a "ringtone" to some schools in Wales where "The Mosquito" device was marketed to. The innovative application of this idea as a "teen only" ringtone spread like wildfire first in England, then the rest of the world in a matter of months with the help of the internet. The use and spread of this idea has since grew to legendary status as another internet curiosity.
