The so-called acoustic attack on the US embassy in Cuba could involve crickets, according to a study by scientists Alexander Stubbs from the University of California and Fernando Montealegre-Dzapata from the University of Lincoln. This is reported by CNN.
Scientists have studied the audio recording agency Associated Press, published in 2017. “At the AP record, there is a reduction in the frequency of individual pulses, characteristic of how crickets make sounds,” the study says.
In 2016, American diplomats in Cuba complained of dizziness, nausea, and hearing problems. In the US, the incident was tied up with sound attacks and in response sent 15 Cuban diplomats out of the country.
Cuban authorities rejected all charges. Local investigators believe that the “acoustic attacks” could be the chirping of crickets or cicadas. The US side also admitted involvement in the incident of the Russian side, but later abandoned this version.
In April 2018, there were reports of acoustic attacks on employees of the US consulate in the Chinese city of Guangzhou. The State Department claims that strange manipulations took several months. Among the effects of the impact was cited, in particular, head injury.
