Why might you see the drummer hit drum before actually hear drums sound if sit in last row of an auditorium during a band concert?

The speed of sound is slower than the speed of light. Sound travels at approximately 343 meters per second, while light travels at approximately 299,792,458 meters per second. This means that if you are sitting in the last row of an auditorium during a band concert, you will see the drummer hit the drums before you actually hear the sound of the drums. The delay between seeing the drummer hit the drums and hearing the sound of the drums is called the latency. The latency will be greater if you are sitting further away from the stage.
