Sound is a wave that travels through matter. It is created when an object vibrates and causes the molecules around it to vibrate. The frequency of the sound wave determines its pitch, and the loudness of the sound wave is measured in decibels. Sound waves can travel through solids, liquids, and gases, but they cannot travel through a vacuum.
