> Earshot used echolocation to analyze the audio on the recordings in order to arrive at precise estimates of the shooters’ locations. Echolocation is the process of locating the source of a sound based on an analysis of the sound’s echoes and the environment in which the sound travels. The Israeli military destroyed and cleared so many buildings in the Tel Al-Sultan area where the ambush of the aid workers took place that very few structures remained. This destruction actually strengthened Earshot’s ability to determine the positions and movements of Israeli soldiers, based on identifying the surfaces responsible for clearly distinguishable gunshot echoes. Rather than having multiple buildings reflecting the sound waves, there were only a few standing walls and the emergency vehicles themselves.

Seems like interesting tech.
