Beat the alarm about the secret sonic weapon. Now think of scientists they have found the answer

For a year and a half ago, spoke of "the whole" world about mysterious attacks aimed at employees at the U.s. embassy in Cuba. In september 2017 was FBI connected into the case, after that 24 employees at the embassy had health problems that were connected to the sonic attack - in other words sounds that are not perceived by the human ear.

The mysterious attacks were first reported to the u.s. government as early as December 2016.

According to The Guardian reported also in Canada, that ten of their diplomats has been hit by similar attacks.

Symptoms included a mild traumatic brain injury, permanent hearing loss, balance problems and headaches, according to a statement from the diplomatic union, the American Foreign Service Association (AFSA).

According to the Washington Post enlightened Trump administration that utvisningene was a protest against that Cuba had not been able to protect the Us diplomats in the country.

In December 2017 said the United states ' then secretary of state, Rex Tillerson, that he was "sure that the attacks were targeted". At one time considered the united STATES to shut down the embassy in Cuba after the mysterious health problems.

Cuba has all the way refused stubbornly for that it was they who were behind it.

- the Country will never allow the attacks against diplomats or diplomatenes family happens on our territory, says in a statement from the government, quoted by The Guardian.

Original recording

A recording of the mysterious sounds were being spread in the news worldwide, including the news agency AP. Friday presented two researchers at, respectively, the british University of Lincoln and the University of California, Berkeley, the findings indicate that the sounds on the recording come from the crickets, an insect in the gresshoppefamilien.

There is plenty of debate in the medical community about which, if any, physical damage these people have got. All I can say fairly safely is that the recording from the AP is of the crickets, and we think we know what art it is to talk about, " says the american researcher, Alexander Stubbs, to the New York Times.

Stubbs and medforsker Fernando Montealegre-Z has published an early draft of forskningsrapporten on the net, and plan to submit it for publication in a scientific journal within a short time.


Stubbs said he immediately recognized the sounds from the time when he was on fieldwork in the Caribbean, and heard the sounds hansirisser expel when they are trying to attract a paringspartner.

The various species of crickets have peculiar paringslyder, and the two scientists believe that nature there is talk about close to the american embassy in Havana, is the west indian korthalsede sirissen. A recording of the insektets paringslyd can be heard here.

The west indian korthalsede sirissens song matches, in nuanced detail, the AP-recording, in the duration, pulsrepetisjonshyppighet, kraftspektrum, pulsratestabilitet and oscillation per pulse, enter the two scientists in his analysis.

Differences in the sounds the diplomats took up, and sirisslyden can be explained by the ambassadeopptaket was done indoors, while the latter recording was made outdoors.

- Incredibly high sound

The american diplomats excluded that insects could stand behind the infernal sound. But Stubbs underlines:

- They create incredibly loud sound. You can hear them from inside a dieseltruck running at 65 km/h.

Stubbs emphasizes that the conclusion about the crickets not mean that the diplomats were exposed to an attack. But the defining characteristic i.e. tilskrivingen of sound as a derailing.

It is certainly possible that they were sick from something completely unrelated that was not a sonic attack, or that they were attacked in a different way, " says the researcher.

This is not the first time someone claims to have found the solution to the mystery. Last year, a research team from the University of Michigan that the sounds could be produced by two ultralydkilder, for example, lytteapparater, who stood close to each other and thus combined with each other to create a new sound.
