Havana Syndrome as Sonic Attack

RecordOBS-0075
CategoryGovernment/Cover-ups
StatusDEBUNKED
SummaryAn early theory proposed that Havana Syndrome was caused by a sonic weapon, possibly using ultrasound or infrasound, directed at U.S. personnel. This theory was popular in the media and among some officials, but later investigations found no evidence of such an attack. The sonic attack theory is now largely discredited.
OriginThe sonic attack theory emerged in 2017 after reports of the symptoms in Cuba, with some officials suggesting a covert acoustic device.
Claimed
  • A sonic weapon was used to harm U.S. diplomats and spies.
  • The weapon may have been operated by Cuba or another adversary.
  • The U.S. government initially covered up or mishandled the investigation.
Evidence / consensusScientific studies and the U.S. intelligence community found no evidence of a sonic attack. The symptoms are not consistent with known acoustic weapons, and no device has been identified.
> OBSERVER NOTE:
The sonic weapon theory was a tantalizing Cold War relic, but the evidence never produced a smoking gun. The archives show only static.
