China develops handheld sonic weapon for crowd control

China has developed the world’s first portable sonic gun to control riots, the Chinese Academy of Sciences announced.

The instrument was jointly created with the deloi and military application and is intended to disperse a range of focused sound waves frequency, according to a report published in the South China Morning Post (SCMP).

The scientists reportedly stated that the “biological effect” of the device was extreme discomfort, causing vibrations in the eardrums, eyes, stomach, liver and brain.

Some studies have indicated that low frequency sounds can cause dizziness, fatigue, trouble, headaches and even heart palpitations.

The news comes as China struggles to solve the problem of the pro- democracy protests in Hong Kong, which have sometimes become violent and have immobilized the city’s airport.


Professor Xie Xiujuan, senior scientist of the project, told the Chinese publication that the device was fed by a tube-shaped container containing an inert gas. When heated, the gas particles vibrate and a deep, monotonous sound is emitted.

However, Xie would not reveal details of the frequency or range of the device.

The prototype has passed field and third-party tests, and scientists have done an assessment of its effects on the body, according to scientists.

SCMP reports that it has also refused to comment on its potential uses without the approval of higher authorities.
