Mike Rugnetta and Atlas Obscura‘s Dylan Thuras have a fascinating discussion on the use of sound in war and at what point sound becomes a weapon. Among the topics covered: - World War I “sound mirrors” (giant concrete parabolas that ineffectively tracked incoming planes) - Project Disperse - The Mosquito - “Tunnel chicken” - LRAD - So-called “less than lethal” technology - Humankind’s unintentional sound war on the animal population
