'White noise' is believed to have been a key element in sensory deprivation techniques since the early 1970s and ultrasonic riot control devices are also believed to have been deployed in quelling civil unrest. One such device - the 'squawk box' - blasts two slightly different, intolerably high-pitched ultrasound frequencies (16,000Hz and 16,002Hz) at rioters; the two, when combined in the ear, effectively produce the frequencies 32,002Hz and 2Hz. The result, as one commentator put it, is to create in the rioters "a compelling wish to be somewhere else". 8 Whilst the military or law enforcement officials have never admitted to its use, or even its existence, instructions on how to build a 'Phasor Pain Field Generator' ("intended for Law Enforcement Personal Or For Qualified Acoustical Research") is available from Information Unlimited, as are schematics for handheld ultrasound self-defence devices. 9
