1,800 > 340.29
I was recently watching Batman: Gotham Knight, a collection of intertwined animated Batman shorts. During one of the segments, "Field Test", Fox invents a gyroscopic emp device to repel bullets. Skipping the actual story and just simply focusing on the science of it the device is explained as being triggered by noises over a certain decibel level. So if the device hears a gunshot it instantly repels metal such as bullets. Now I'm no scientist, but it seems to me that bullets travel relatively faster than the speed of sound. If you look it up on Wikipedia most guns have a muzzle velocity of up to 1,800 meters per second. Sound only travels at 340.29 meters per second. That means that by the time the device detects the sound of the gunshot poor batman would already have a gaping chest wound. Now like I said, I'm no scientist... so I could be wrong. But that seems to be about right to me.
