The Ig Nobels celebrate the quirkier side of serious scientific endeavour, honouring "achievements that first make people laugh, and then make them think". The Mosquito won the satirical Ig Nobel for "peace" in 2006. This ringtone became informally known as "Teen Buzz" or "the Mosquito ringtone" and has since been sold commercially. Mobile phone speakers are capable of producing frequencies above 20 kHz. The sound was made into a mobile phone ringtone, which could not be heard by teachers if the phone rang during a class. In February 2008, in response to a national campaign launched by the Children’s Commissioner for England, Liberty, and the National Youth Agency, the government issued a statement insisting that "'Mosquito alarms are not banned and the government has no plans to ban them". They must ensure these systems comply with the law." A Newport Community Safety Partnership spokesman said: "Any view expressed by the Partnership does not stop any business or private company from purchasing these devices. Despite the ban, another Spar shop in Newport installed the device. It requires a 24-volt DC or 15-volt AC power supply.Ī device installed in a Spar shop in Caerleon Road in Newport, South Wales was banned after three months by the Newport Community Safety Partnership, a partnership set up to meet the requirements of the Crime and Disorder Act 1998, with members including Newport City Council, Gwent Police, Newport Local Health Board, South Wales Fire Service, representatives of Customs and Excise, and the Welsh Assembly Government. The range of the sound is 140 feet (43 m) with the sound baffle, and 200 feet (61 m) without. The current device has two settings: the high frequency sound targeted at youth, and another that can be heard by everyone. The Mosquito was released to the mainstream market in 2005, through Stapleton's company Compound Security Solutions. Using his children as test subjects, he determined the frequency of "The Mosquito". The push to create the product was when Stapleton's 17-year-old daughter went to the store to buy milk and was harassed by a group of 12- to 15-year-olds. The idea was born after he was irritated by a factory noise when he was a child. The Mosquito machine was invented and patented by Howard Stapleton in 2005, and was originally tested in Barry, South Wales, where it was successful in reducing teenagers loitering near a grocery store. The ability to hear high frequencies deteriorates in most humans with age (a condition known as presbycusis), typically observable by the age of 18. The maximum potential output sound pressure level is stated by the manufacturer to be 108 decibels (dB)(comparable in loudness to a live rock concert) and the manufacturer's product specification furthermore states that the sound can typically be heard by people below 25 years of age. The latest 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 young people, and another at 8 kHz that can be heard by most people. Nicknamed " Mosquito" for the buzzing sound it plays, the device is marketed as a safety and security tool for preventing youths from congregating in specific areas. In some versions, it is intentionally tuned to be heard primarily by younger people. The Mosquito or Mosquito alarm is a machine used to deter loitering by emitting sound at high frequency.
