Where can a long range acoustic devices system be used?
The long range acoustic devices system has strong sound propagation directivity and has little impact on the surrounding irrelevant areas. It has been used as a non-lethal dispersal weapon by military and police in many countries, including China and the United States. Similar devices are equipped on Chinese and US warships patrolling the Gulf of Aden, and they have played a huge role in anti-piracy operations.
The mass notification speaker system can also be used for long-distance warning at highway entrances and exits, and for driving away insects and birds in forests.
How does a long range acoustic devices system(LRAD) work?
The long range acoustic devices system is designed with three bypass speakers on the front. The sound is compressed and concentrated by the sound wall, so that the sound waves can propagate forward along the device without radiating to the sides, thus reaching farther.
What are the benefits of using a long range acoustic devices system?

The long range acoustic devices system is used for long-distance voice warning and noise dispersal.
(1)Strong directivity, with little impact on the surrounding irrelevant areas.
(2)High sound pressure level, with strong sound intensity, which has a deterrent effect.
