What are sonic weapons?

Bu bölüm hakkında

In June it emerged that Greek police had acquired two long range acoustic devices, designed to discourage migrants from approaching the country's border with Turkey. At the size of a small TV, the cannons don’t look particularly threatening, but are capable of emitting powerful sound waves as loud as a jet plane. An LRAD is an example of a sonic weapon, which is an umbrella term used to cover the many different types of acoustic harassment devices. They emit a particularly audible sound in a precise direction, making it very unpleasant for those who get close. The use of LRADs has been a source of controversy in a number of scenarios. In addition to the pain and disorientation caused, their alert feature has been reported to cause lasting hearing damage. In what other scenarios are sonic weapons used?
