Light versus Sound

We were sitting in the highest section of the football stadium for the last game, and we noticed that when the band was doing the pre-game performance, we would see them striking the drums, but we would hear the sound of the drum a few instants afterwards.  I was mindful that his is because the speed of light is faster than the speed of sound. The speed of light is the fastest speed that energy and matter could ever travel. Speed of light is 299,792,458 m/s while the speed of sound in dry air at 20degrees Celsius is 343.2m/s.
