A team of computer scientists from the University of Michigan may have solved the mystery behind strange sounds heard by American diplomats in Havana, who later suffered a variety of medical disorders.
Professor Kevin Fu and members of the Security and Privacy Research Group at the University of Michigan say they have an explanation for what could have happened in Havana: two sources of ultrasound—such as listening devices—placed too close together could generate interference and provoke the intense sounds described by the victims.
The health incidents, which took place between November 2016 and August 2017 at homes and two Havana hotels, made 24 intelligence officers, diplomats, and relatives based in Havana ill. Many reported a variety of symptoms such as hearing loss, headaches, cognitive problems, and other ailments that doctors said correlate with concussions. The cause has perplexed the U.S. Department of State, the FBI and other U.S. agencies.
