Ultrasonic eavesdropping and microphone jamming- researching Cuban ailments
Kevin Fu and Wenyuan Xu, researchers with the University of Michigan and Zhejiang University in China, study the use of ultrasonic waves that may have been a possible source of recent ailments of diplomats living in Cuba. Causes of the symptoms of the diplomats and their families have not yet been confirmed, but one of the possible causes offered was the use of some sort of sonic "weapon". Hearing about this caused Fu and Xu to wonder if ultrasound could be the culprit. Their research tries to explain possible ways the effects that were described could have been created leading them to also investigate ultrasonic eavesdropping and microphone jamming.
