Sound as a weapon: Chinese scientists develop handheld sonic weapon for crowd control
[Sadly, I only have access to a small portion of the article. Jan]
China has developed the world’s first portable sonic gun for riot
control, the Chinese Academy of Sciences said.
The rifle-shaped instrument, which was jointly developed with military and law enforcement, is designed to disperse crowds using focused waves of low frequency sound, the academy’s Technical Institute of Physics and Chemistry website said on Wednesday.
The device’s “biological effect” would cause extreme discomfort, with vibrations in the eardrums, eyeballs, stomach, liver, and brain, scientists said.
