The perpetrators of the “acoustic attack” on the U.S. diplomats in Cuba called crickets

Sounds that American diplomats in Cuba took over the acoustic attack could be the chirping of crickets. To such conclusion scientists have come, according to CNN.

The us authorities claim that in Havana from 2016 to 2017 from the “acoustic attack” suffered 24 diplomat.

They complained of hearing loss, nausea, headaches and impaired coordination. The US has been blamed on Cuba and withdrew 60% of the staff of its Embassy.

Later an audio recording of troubled diplomat sounds published the Associated Press (AP).

Professor of sensory biology Fernando Montealegre-Zapata from a British University and an American researcher Alexander Stubb came to the conclusion that the published sounds to the smallest detail — in duration, the pulse repetition frequency and the energy spectrum coincide with the chirping of crickets, says CNN.

The specialists admit some variance, as the recording was not done on the street, and indoors.

“Record AP also shows the fading frequency in individual pulses, this is a distinctive acoustic feature of sound production in crickets,” said Montealegre-Zapata.

Scientists have even determined the species of the cricket — Indian short-tailed.

The Cuban government has repeatedly denied carrying out “acoustic attack”, pointing to the unsubstantiated statements of Washington. In 2018 the United States were evacuated from the Consulate General in Guangzhou, China 11 diplomats also allegedly due to sound exposure.

In September, the American media with reference to intelligence agencies said to the “acoustic attack” involved Russia.
