3.Applications
Back-up alarm is a device intended to warn passers-by of a vehicle moving in reverse. They typically produce 1000 Hz pure tone beeps at 97-112 decibels. Matsusaburo Yamaguchi of Yamaguchi Electric Company, Japan, invented the back-up beeper. It was first manufactured as model
BA1 in 1963. ISO 6165 describes "audible travel alarms", and ISO 9533 describes
how to measure the performance of the alarms.
Back-up beepers are criticized by the public and in scientific
literature. Beepers top lists of complaints to government
roadbuilders about road construction noise. There is published
concern that people become habituated to the ubiquitous noise, diminishing its effectiveness. The normal
level of 1000 Hz pure tone beeps at 97-112 decibels, considerably higher than the long-term hearing loss limit of 80 decibelsStrategies such as adjusting the volume
according to the ambient noise and changing the tone to include
sounds above 1600 Hz and below 800 Hz for improved localization
would improve the alarm, but improvements are not cost-effective
for the manufacturer and, if implemented by the equipment owner,
introduce liability for the owner.
Brains do not adapt to the repetitive and persistent sound of
back-up beepers, but have evolved to process natural sounds that
dissipate. The sound is perceived as irritating or painful, which
breaks concentration.
While not addressing the criticism of the type of sound, units
exist that moderate the volume based on sensing ambient sound.
