In what is becoming an increasingly alarming mystery, U.S diplomats and their families are being evacuated out of China after hearing stranges noises and falling ill. The strange sounds have been compared to hearing cicadas, the waving of metal sheets or static. After hearing the sounds, people complain of symptoms similar to a traumatic brain injury, such as headaches, nausea, cognitive issues and hearing loss.
What is most frightening is this is not new. It has happened before in Cuba in 2016 where 24 American Embassy employees fell ill after hearing similar sounds. The unknown reason for the illnesses strained relations with Cuba causing the United States to expel Cuban diplomats.
At the time the Associated Press theorized that the events in Cuba could have been caused by the use of “an advanced sonic weapon that operated outside the range of audible sound.” It was guessed that devices were being placed in the diplomates homes. Others speculate that spy gear placed to close together could interact sending out the strange sounds and causing the illnesses.
The latest reoccurence of this mystery led State Department to issue a health warning for US citizens in China.
