High Quality Content by WIKIPEDIA articles! The Mosquito or Mosquito alarm (marketed as the Beethoven in France and the Swiss-Mosquito in Switzerland) is an electronic device, used for solving loitering problems, which emits a sound with a high frequency. The newest version of the device, launched late in 2008, has two frequency settings, one of approximately 17.4 kHz that can generally be heard only by people under the age of 25, and another at 8 kHz that can be heard by most people. The maximum potential output sound pressure level is stated by the manufacturer to be 108 decibels (dB). The sound can typically only be heard by people below 25 years of age, as the ability to hear high frequencies deteriorates in humans with age (a phenomenon known as presbycusis).
