On the 16th of March 2025, Earshot was contacted by activists in Serbia to investigate the potential use of sonic weapons by the government on a crowd of protestors as they were holding a silent vigil for the victims of the Novi Sad railway station canopy collapse. Earshot

On the morning of October 18th, Israel Defence Forces released this video x.com/IDF/status/171…. Earshot.ngo performed an audio analysis and found that this recording was manipulated and cannot be used as a credible source of evidence. 1/4

Islamic Jihad struck a Hospital in Gaza—the IDF did not. Listen to the terrorists as they realize this themselves:

Earshot.ngo performed a Doppler Effect analysis from two videos from the missile attack on the Al-Ahli hospital. The results cast doubt on the IDF’s claim that the missile that hit the hospital approached from the south-west. #AlAhli #IDF 1/7

When calls are intercepted, we would expect them to be single monophonic recordings with both voices on the same channel of audio. What is unusual in this alleged intercepted call is that we have the voices divided across two channels, left and right. 2/4

Though this audio analysis cannot categorically state that the audible dialogue is fake, Earshot.ngo’s opinion is that the level of manipulation required to edit these two voices together disqualifies it as a source of credible evidence. 4/4

The fact that this recording is made up of two separate channels demonstrates that these two voices have been recorded independently. These two independent recordings have then been edited together with added effects (such as pan control). 3/4

Following the alleged sonic attack on thousands of people holding a silent vigil during the mass protest in Belgrade, Serbia, on 15 March 2025, Earshot conducted a comprehensive investigation. This included analysis of audio from 19 videos, the aggregation of over 3,000 written

This increasing pitch suggests the missile is continuously accelerating towards the camera until impact. The camera’s north-western location suggests an eastern missile trajectory, further decreasing the probability that the missile approached the hospital from south-west. 7/7

However, the Doppler Effect that we hear indicates that the missile was closer to the camera before hitting the hospital. This would mean that the missile approached the hospital from north-east, east or south-east. #AlAhli #IDF 5/7

The Doppler Effect is a change in the observed frequency emitted by a sound source that is moving relative to an observer. In the first video, taken 150m south-east of the hospital, we hear a pronounced frequency increasing in pitch and then decreasing until impact. 2/7

A second video captures the moment of the strike from around 1,500 meters north-west of the hospital. In this video, the missile can be heard moving with a less pronounced Doppler Effect, where the pitch is increasing up to the moment of the explosion. #AlAhli #IDF 6/7

The IDF claimed the missile was fired by the Islamic Jihad from a south-western location. If this was the case, we would expect the pitch observed by this camera to increase continuously until the missile’s impact. #AlAhli #IDF 4/7

The increasing pitch suggests the missile is accelerating towards the camera. The decreasing pitch suggests that the missile is now moving away from the camera while still accelerating, upon the missile’s impact. #AlAhli #IDF 3/7

Listen here to the reconstructed sound of the sonic attack on protesters in Belgrade, Serbia on 15 March 2025. Earshot was able to produce this reconstruction through 15 in-depth earwitness interviews and through an analysis of over 3,000 written testimonies. Witnesses
