Electrophonic Noise:

This term is used to describe phenomenon reported to have accompanied the passage of meteoroids through the atmosphere. The witnesses will state that they have hear sounds and felt  physically things at the same time as they saw the meteor in the sky. The difference in the speed of sound and that of light would preclude this if the sensations were sonic. Therefore the cause of these sensory responses travels at light speed. The best current guess is that they are electrically caused by the meteoroid's passage through the upper atmosphere.
