In the PBC Palestine footage the sound of 5 gunshots can be clearly identified and isolated. Each of these shots are fired from close to the area the soldiers are positioned in the CNN footage.
The fourth gunshot in this sequence is the shot that killed Mohammed Abu Daher.
What is the sonic difference between the gunshot that killed Mohammed Abu Daher and the 4 other gunshots fired at the protesters recorded by PBC Palestine? If you listen carefully you can hear the difference between the shot that killed Abu Daher and the other non-lethal shots from the same day even without the visualisations.
In the image above we compare the shot that killed Mohammad Abu Daher (the shot on the far left) with 4 other shots fired on the protesters in the same footage. In this comparison we see that the shot that killed Mohammad Abu Daher is distinct from the others in two key ways.
- The shot that killed Abu Daher is much louder in the higher frequencies from 17 khz and above. Moreover it is the only shot to occupy frequencies from 19khz – 22khz
- The shot that killed Abu Daher is not as loud in the lower frequencies and this is especially observable when we compare this spectrograph with the 4 others at 1khz and below.
This is the same pattern of acoustic variation between live ammunition and rubber-coated bullets that was observable in the CNN footage that showed the killing of Nadeem Nawara. By using the sonic signature of live ammunition and rubber bullet fire from the Nawara case we can deduce from the comparative acoustic behavior of the above gunshots that the shot that killed Mohammad Abu Daher is live ammunition and that the four other shots are rubber coated bullets.
