From late 2016 U.S. and Canadian diplomats in Havana, Cuba, reported symptoms including headaches, dizziness and hearing loss, sometimes after hearing strange sounds — the cases later called Havana Syndrome. In 2018 the JASON scientific advisory group studied recordings of the sounds for the State Department and concluded they were most likely made by crickets.[1][2]
The JASON study
JASON analysed audio from eight of the original 21 Cuba cases and two cellphone videos from one patient. It identified two of the audio sources with high confidence as the call of the Indies short-tailed cricket, and judged that microwave or ultrasound sources were highly unlikely to explain both the recorded sounds and the symptoms; it suggested that psychogenic effects might explain important components of the reported injuries. Its findings were first reported in July 2019, and parts of the report were declassified in September 2021.[1][2][3]
Other assessments
A National Academies of Sciences, Engineering, and Medicine panel, commissioned by the State Department, reported in December 2020 that directed, pulsed radiofrequency energy was the most plausible explanation for some cases, while stressing that every cause remained speculative. In March 2023 a U.S. intelligence community assessment found no credible evidence that a foreign adversary had a weapon causing the incidents, with five of seven agencies judging foreign involvement very unlikely; studies by the National Institutes of Health in 2024 found no brain injuries compared with control groups. A January 2025 update noted that two agencies had slightly changed their views on a possible foreign capability.[1]
The Moscow Signal
The testimony links the issue to the long history of microwave research going back to the Moscow Signal, the low-level microwave beam the Soviet Union aimed at the U.S. Embassy in Moscow from 1953 to 1976; critics of the microwave theory have cited a 1978 study that found no adverse health effects from that beam.[1][4]
