Beginning in late 2016, a mysterious illness befell U.S. diplomatic personnel and family members in Havana.
Specialists said the symptoms, described by those afflicted as “buzzing, grinding metal, piercing squeals and humming,” were similar to the brain dysfunction caused by concussions.
Some U.S. officials suspected the “health attacks” were intentional, perhaps perpetrated by the Cuban or Russian governments, but new research has implicated another culprit: Very loud crickets.
Scientists analyzed a recording of the sound released by The Associated Press in 2017 and found it matched the chirp of the Indies short-tailed cricket Anurogryllus celerinictus “in duration, pulse repetition rate, power spectrum, pulse rate stability, and oscillations per pulse.”
This particular kind of cricket is typically found in the Caymans, Florida Keys and Jamaica, but researchers Alexander L Stubbs of the University of California Berkeley, and Fernando Montealegre-Z of the University of Lincoln in England believe they may also be present in Cuba.
The researchers noted that the pulse structure of the AP recording initially didn’t match outdoor field recordings of the insects, but when the cricket call was played indoors, “the interaction of reflected sound pulses yields a sound virtually indistinguishable from the AP sample.”
They said their research, which has not yet been peer-reviewed, provides “strong evidence” that crickets produced the sound on the recording. However, their findings highlight the need for more rigorous research on what caused the diplomat’s ailments and does not rule out the possibility of another form of attack, according to the report.
