Ground Or Not To Ground Receiving Antenna In Storm ?

This is the first time I have seen it mentioned the ear reacting to the electromagnetic pulse. Most of the time it is described as the same way the old WW2 depth charges sounded in the submarines. YOu get the click and then the boom. I forgot the term used but it is something like an impulse or pressure shock wave traveling faster than the speed of sound and then the actual sound wave. I do believe that any mechanical wave, such as a pressure or shock wave, travels at the speed of sound, no more and no less. To travel faster, it would have to be an electromagnetic wave.
