Sound as a Military Weapon
Long-range acoustic devices (LRADs), whose development began in 2000, are used to issue warnings and disperse crowds. Some models can project sound over distances of up to two kilometres. However, exposure at a distance of 15 to 20 metres can cause hearing injuries, and the LRAD-500X produces sound at around 154 decibels. Acoustic weapons raise health and legal concerns, while evidence of harm from infrasound remains limited. Investigations have not established that a foreign state was involved in cases of “Havana syndrome.” Experts recommend using these devices only when necessary and subjecting them to strict controls to protect civilians.
