The speed of light is 186,000 miles per second. The speed of sound is about 1,108 feet per second, which is 0.2098 miles per second! The speed of light is about 886,559 times faster than the speed of sound!! Light travels at 299,792,458 meters per second. The speed of sound is 340.29 meters per second at sea level. 299,792,118 is the difference of meters per second.
According to Physics Web in 'Sound breaks the light barrier,' a professor of physics in Tennessee has designed an experiment which proves that sound can move faster than light. This looks like impossible -- and it is. In fact, the physicist has tweaked some scientific definitions. No sound can go faster than light. But a sound pulse, or more precisely, all the wavelengths associated to a sound, have a group velocity that far exceeds the real physical limits.
