Great question! You probably know the everyday use for sound energy, hearing! We're able to enjoy music thanks to sound that comes from vibrations. For example, beautiful music is created from a violin string vibrating. Also, sound energy is used for mapping the ocean floor by SONAR. The sound travels through the water and bounces off objects. This allows us to "see" underwater and ships to avoid obstacles. Another use is in medicine. With sound energy, we're able to see inside people. We can then use sound energy to blast apart harmful tumors.
