By radio signals of different ranges
For radio broadcasting, sound waves are converted to electrical waves that are further transmitted. This transformation is done by a device called a transducer, which converts physical parameters into an electrical form (signals).
Sound travels at the speed of sound, whereas radio waves travel at the speed of light. The speed of radio waves is much faster than the speed of sound. If you're seated high in the stands at a baseball game, watching it on the field and listening to the game on the radio at the same time, it's quite common to hear the crack of the bat on the radio before you hear it straight from Home Plate.
Any decent car stereo installer will have them, or can order one or can custom wire one for you if needed.
