Between the yelling of sergeants, the rumble of jet engines, and the deafening pop of gunfire, a soldier's sense of hearing rapidly deteriorates in the heat of battle. Luckily, the Dutch company Microflown has designed a special microphone that can do a soldier's listening for him. By measuring the mechanical movement of individual air particles, as opposed to sound waves as a whole, the device can not only pinpoint the origin of sniper fire or approaching aircraft, but detail their make and model, as well.
