Teen Buzz is a popular ringtone that was hijacked from a technology that was originally used to repel loitering teenagers from shops in the United Kingdom. Inventor Howard Stapleton developed the "Mosquito device" for Compound Security Systems. This device emits a modulated 17khz sound that proves to be a great annoyance to teenagers or anyone younger, but leaves most over twenty years of age unaffected. This is due to Presbycusis, a normal loss of acute hearing that occurs with advancing age. Teen Buzz was developed to combat The Mosquito device using the same technology, but as a constant 14.4khz high frequency ringtone. It is primarily used in the classroom, allowing students to be alerted of incoming text messages on their mobile phones without the knowledge of their teachers. Stapleton is impressed and admits the idea to being humorous, but he thought it might be an infringement on his intellectual property rights.

History[edit]

The story goes back to 2005, when a British inventor named Howard Stapleton came up with a security device designed to keep teenagers from congregating in malls, taking up space and driving away the money-spending customers. It was marketed as an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer designed to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected. The product, called The Mosquito, took advantage of a singularity that most adults (and kids) are not aware of: Certain high-frequency tones are apparently undetectable to the human ear after a certain age, a condition known as [presbycusis].

Apparently some teens in Birmingham (the inventor's hometown) got wind of what the company was doing, and decided to appropriate it for their own use: They created a cell phone ringtone called "Teen Buzz," which has caught on like wildfire, first in the UK, and quickly emigrating to the US.

British newspapers described the first use of the high-frequency ring tone on May 2006 in some schools in Wales, where The Mosquito device was introduced as a "yob-buster," a reference to the hooligans it was meant to disperse.also it is very popular to all teenagers for ringtones so adults cant hear

Presbycusis[edit]

The principle behind it is a biological reality that hearing experts refer to as presbycusis, or aging ear. Starting at about 20, scientists say, the human ear loses its ability to hear tones in the highest human-range frequencies (18-20 khz), and the older you get, the harder it is to detect these sounds.

Most adults over 40 or 50 seem to have some symptoms of this condition, but younger adults are usually asymptomatic, as most human communication takes place in a frequency range between 200 and 8,000 hertz, leaving the deterioration of the ability to hear frequencies higher than that undetected.

The Mosquito[edit]

The Mosquito device is manufactured by the british company Compound Security. Once installed on a building, emits a high-pitched sound (at 17 kilohertz), like a constant insect buzzing, but about 10 times more annoying. The product is based on the idea that, as people age, they are less able to hear high-frequency sounds, making this particular sound annoying only to youngsters.

This sound, beamed at kids congregating in a section of the mall, would encourage them to move on, the theory goes, therefore preventing unwanted gatherings of youths and teenagers in shopping malls and around shops or chasing them away.

Mosquito devices have been sold around the world since its launch on 2005. Police forces and small business have praised the Mosquito device and say it has improved business and community trouble spots.

It has since been welcomed by many as an important step forward in crime prevention, and by others as an attack to the human rights and the health of those affected.

Teen Buzz[edit]

The Teen Buzz Ringtone (also known as Mosquito Ringtone, Mosquitotone or Zumbitone) is a cell phone ring tone that is too high-pitched for most adults to hear. It is a constant high-frequency (14.4 khz) tone, while the sound generated by The Mosquito device is a modulated 17 khz sound, according to its inventor, Howard Stapleton.

In settings where cellphone use is forbidden — in class, for example — it is perfect for signaling the arrival of a text message without being detected by an elder of the species. Although students reportedly succeeded in using their cell phones without their teacher knowing, there are growing reports of adults who hear the tone perfectly (read below, Can You Hear It?).

Simon Morris, marketing director for Compound Security, said to The New York Times that his company has received so much attention - none of it resulting in a profit, because the ring tone was, in effect, pirated - that he and Stapleton decided to start selling a ring tone of their own. It is called Mosquitotone, and it is now advertised as "the authentic Mosquito ring tone."

Can You Hear It???[edit]

As more people report on the Internet their ability – or lack of ability – to hear the infamous ringtone, it is becoming every day more evident that people are not alike.

Although it is clear that the chances of hearing perfectly the sound decrease markedly with aging, there are many reports of people aged as old as 50 who allegedly hear the sound of the ringtone as clear as their younger counterparts (see Table below).

WHAT ABOUT YOU? CAN YOU HEAR IT?

34 yrs old, & can hear it clearly! So annoyingly funny!! PLEASE STATE YOUR AGE, COUNTRY, AND ANSWER "CAN YOU HEAR IT?" --> 32 years old and I can hear it, on and IMAC computer speakers, I played it while there were 3 more people in the room, 2 over 50 did not hear it, 1 who is 40 heard it, however when i played the sound off my smartphone speakers all heard the buzz.

Heard by an almost 35 yr. old female - can't hear anything past 19.5khz.

PLEASE SIGN BY TYPING FOUR TIMES ~ I'm 32 from Scotland in the UK and I can hear it quite loudly. It seems to die away rather than just stop and I found myself pulling a face whilst listening as it was soooooooooooo annoying! They've just fitted one of these in my neighbourhood to try and deter young kids hanging around. Don't know what the outcome will be.

I'm 12, in Arizona, and I can hear it. Very loud. My grandma is 63, and she can even hear it.

I´m 33, from Brazil, and didn´t hear a thing. And I know people above 40 who did... damn it. Zumbitone 07:56, 23 June 2006 (UTC)

I just turned 20 and am from the US. I can hear the tone, but not as loud as my 15 year old brother describes it. Just be wary that some websites have the sample in mp3 mode which can downgrade the quality and would be at a lower frequency than 17KHz which allows older people to hear it. Try finding a sample in wav format. Here's the one I used: http://www.jetcityorange.com/toys/17KHz.wav. Ignore the popping noise in the file. [[User:] 05:44, 30 June 2006 (UTC)

17 in the US. I can definitely hear it, and it sure does HURT!

30 in the USA. I can definitely hear it and it hurts my ears~ Nuts to that, at least I am not as old as I thought I was~ =P AMG

38, United States: Ouch I can definitely hear it. My ears are still ringing even after I turned it off. The ringing in my head that I have now reminds me of the high pitch noise I hear after I have spent a night at the bars listening to loud music.

24, US: YES I can definitely hear it. Sometimes I grow used to it and I can't hear it anymore. I am definitely using this on the neighbor's dog.

12, Toronto Canada : OMG this is frickn awesome!! though, u shud listen to a nother file which is 23 khz . I couldn't even hear that one just at the beginning and tats it

OMG.... I was sitting in school....I am in 12th grade and i am 18.....and at lunch people were talking about this noise that only kids can here. I asked to here it and it was so high pitched it reminded me of someone being torchered. lol it was great so i downloaded it and had fun. now 1/2 the school has it b/c we all blutooth it to eachother. Some teachers ( the younger ones ) can here it and some students cant. I think it is so kewl for someone to make stuff like this and that more should be made. I am from MISSOURI in the U.S.A.
