The Mosquito

Anti-loitering sonic device

The Mosquito

Summary

Anti-loitering sonic device

A Mosquito device mounted outside a store in [[Philadelphia

The Mosquito or Mosquito alarm is a machine used to deter loitering by emitting sound at high frequency. In some versions, it is intentionally tuned to be heard primarily by younger 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.

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. 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 ability to hear high frequencies deteriorates in most humans with age (a condition known as presbycusis), typically observable by the age of 18.

History

The Mosquito machine was invented and patented by Howard Stapleton in 2005, and was originally tested in Barry, Wales, where it was successful in reducing teenagers loitering near a grocery store. The idea was born after he was irritated by a factory noise when he was a child. 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. Using his children as test subjects, he determined the frequency of "The Mosquito".

The Mosquito was released to the mainstream market in 2005, through Stapleton's company Compound Security Solutions. The current device has two settings: the high frequency sound targeted at youth, and another that can be heard by everyone. The range of the sound is 140 ft with the sound baffle, and 200 ft without. It requires a 24-volt DC or 15-volt AC power supply.

A 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. Despite the ban, another Spar shop in Newport installed the device. 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. They must ensure these systems comply with the law."

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".

Teen Buzz ringtone

The sound was made into a mobile phone ringtone, which could not be heard by teachers if the phone rang during a class.{{cite web

Awards

The Mosquito won the satirical Ig Nobel for "peace" in 2006. The Ig Nobels celebrate the quirkier side of serious scientific endeavour, honouring "achievements that first make people laugh, and then make them think".

Health effects

The German Federal Institute for Occupational Safety and Health stated in a report on The Mosquito, entitled Use of ultrasonic noise channels not entirely safe:

The results of the examination are now available. The auditors were not able to certify this device as completely safe.

The risk to the target group of teenagers and young adults is relatively low. They can leave the area when they hear the sound. On the other hand small children and infants are especially at risk, due to lengthy exposure to the sound, because the adults themselves do not perceive the noise. Moreover, the ultrasound affects not only hearing. Disruption of the equilibrium senses, as well as other extra-aural effects are well known. With the sound levels that can be reached by the device, the onset of dizziness, headache, nausea and impairment is to be expected. This is not the limit of the total risks to safety and health.}}

In a United Kingdom survey of the relevant studies of adults exposed to high frequency sound in an occupational context for the Health and Safety Executive (HSE) in 2001, it was concluded that the studies were inadequate to establish guidelines for safe exposure. The Mosquito's manufacturer relies on these inconclusive adult studies to justify the safety of the device.

The National Autistic Society said in 2008 that it was "extremely concerned" about possible harmful effects of the devices upon autistic people. Since autism can cause auditory hypersensitivity, autistic individuals with can have more intense reactions to this sound, especially if they are also under 25. Since autism can also affect communication skills, some individuals may not be able to communicate their discomfort to caregivers. A supermarket in Longridge, England, removed a mosquito device in 2008 after a campaign by a 19-year-old Paul Brookfield, who is autistic. Brookfield stated that the device was causing him pain due to his hypersensitivity.

Other disabilities and conditions may be exacerbated by the device. In March 2009, a child who had recently undergone ear surgery reported that the device set off her tinnitus, causing significant pain.

Reception

Support

The Mosquito has received support and endorsements from municipalities, school districts, property management companies, convenience stores and other organisations. Rochdale Safer Communities Partnership said the borough was committed to the continued use of the Mosquito:

"We feel totally justified in deploying Mosquito devices in the borough of Rochdale to give the community respite in cases of acute anti-social behaviour and youth nuisance," she said. "We use the devices when there are large groups of young people making life a problem for residents and businesses, as we are very keen not to let problems of anti-social behaviour escalate."

The Association of Convenience Stores (ACS) also supports the usage of the device, and so does British Retail Consortium (BRC), stating that "Not all young people are involved in violence, but given that some retail staff are facing a level of insolence [from teenagers] they have to have the option of doing what they can to protect themselves. They are entitled to discourage threatening groups from hanging around or in their shops."

At the Maple Ridge, Pitt Meadows and Vancouver west side school districts in British Columbia, Canada, the device has been credited with lowering exterior vandalism at one school by about 40%.

Opposition

Opposition categorises it as an indiscriminate sonic weapon which succeeds only in demonising children and young people and may breach their human rights.

A UK campaign called "Buzz off" is calling for The Mosquito to be banned.

The device was singled out for criticism in a joint report by children's commissioners for all parts of the UK, which formed part of a United Nations review of standards in the UK.

In January 2011, the device was banned on all Council and Partnership buildings in Sheffield following a successful campaign led by the then Member of UK Youth Parliament for Sheffield, Harrison Carter. Sheffield is the largest city in the country with such a ban in place. It was recognised by the UK Government in their Positive For Youth document, published by the Department for Education in January 2012. This strategy paper acts to set out a new-approach to cross government policy for young people aged 13–19. Although mentioned in the document, a national ban of the mosquito device was not in the Coalition Agreement, and is not part of current Government policy.

In July 2014, a new campaign was started in order to get a mosquito device removed from the public library in Milford Haven, Pembrokeshire. However, the campaign was unsuccessful.

In 2016, a shopping centre in Queensland, Australia removed the device after two years of campaigning by a local lawyer, due to it discriminating against young people. It had been installed in the centre for 10 years.
