The international non-governmental organization "Earshot", which deals with audio research, has reconstructed, based on the testimonies of protesters, the sound heard during the mass protest on March 15th in Belgrade, which they say was a "sonic attack".
The organization posted a recording of the reconstructed sound on the social network X and stated that it was created based on more than 3.000 written statements and interviews with eyewitnesses.
"Witnesses consistently describe the sound as 'machine-like', 'vehicle-like', felt as much as heard, approaching rapidly and 'passing through' the body - an indescribable and anomalous sonic phenomenon experienced by thousands of people," according to the Earshot organization.
The organization previously said that protest participants were "very likely" subjected to a "targeted attack using directed acoustic weapons."
Following allegations that an unauthorized sound weapon was used against peaceful demonstrators at a March 15 protest, Serbian authorities have requested that Russian investigators conduct an "independent investigation."
Serbian President Aleksandar Vučić announced on April 16 that the Russian Federal Security Service (FSB) had concluded that the "sonic cannon" was not used.
In addition to the Russian FSB, authorities have also called on the US Federal Bureau of Investigation (FBI) to conduct an independent investigation.
There is no information, however, on how the FBI responded to the Serbian authorities.
There is currently no official information about what caused fear and panic among the protesters, and the authorities have rejected the accusation that security services, such as the army and police, used a "sonic cannon."
In a few days, they went from saying that the police do not have a "sonic cannon", to threats that anyone who spreads "such deceptions" and "disturbs the public" will be prosecuted, to admitting that the police do have sonic devices, but that they have "never used them".
An investigation has been requested by the judicial authorities by the blockaded students who are leading mass protests in Serbia, as well as dozens of non-governmental organizations.
At the request of several non-governmental organizations from Serbia, the European Court of Human Rights is also conducting an investigation into the incident at the protest.
