Acoustic wave generators were installed on the Kozak-2 and Novator armored vehicles of the National Guard. These LRADs are non-lethal weapons, originally designed to protect surface ships and vessels from attacks by terrorists and pirates. However, the weapon can cope with the crowd with the help of low-frequency sounds of high power up to 150 dB. Note that the death threshold for humans is -175 dB. Exposure from LRAD can be harmful to health.
The range of the installation is 500 meters, the angle of attack is 30 degrees. If you get closer to the generator by less than 15 meters, then there is a critical damage to the hearing organs.
