mosquito

[mə′skēd·ō]

(invertebrate zoology)

Any member of the dipterous subfamily Culicinae; a slender fragile insect, with long legs, a long slender abdomen, and narrow wings.

mosquito noise

A distortion that appears near crisp edges of objects in MPEG and other video frames that are compressed with the discrete cosine transform (DCT). It occurs at decompression when the decoding engine has to approximate the discarded data by inverting the transform model. The mosquito noise appears as random aliasing in these areas and requires sophisticated detection circuits to eliminate it. As TVs get larger, mosquito noise and other artifacts become more noticeable. See artifact. See also Mosquitotone.

Mosquitotone

A cellphone ringtone that uses a constant, 14.4 kHz frequency generally only heard by people under 20. Also known as "Teen Buzz" or "Mozzy Tone," it became popular because parents and teachers usually cannot hear the high-pitched tone when the phones are ringing. After 20, most people's ability to hear these higher frequencies begins to decline; however, some aged 50 and older have been known to recognize the ringtone.

Keep Teenagers From Loitering
The Mosquitotone uses a constant 14.4 kHz sound; the idea taken from the modulated 17 kHz tone of the Mosquito sound-emitting device introduced in Wales in 2005 from Compound Security Systems (www.compoundsecurity.co.uk). The Mosquito was designed to prevent teenagers from loitering in the area. After a few minutes, the sound becomes very irritating, and the crowd tends to move to another venue. See ringtone.
