It all starts from a radio with a loudspeaker. It produces and converts electrical energy and make this a formed of kinetic energy coming out of the speaker. Then, when this kinetic energy is moving and transferred to surroundings or air, it will let people feel the motion being created by the air. Finally, it reaches the people and hears this as sound.

This is an example on how we trace the transformation of on signal from radio and how it reaches to people as sound or as a music.
