Sound energy is a form of energy produced by vibrating objects. When an object vibrates, it creates pressure waves in the air, which we perceive as sound. These vibrations can travel through various mediums, including air, water, and solids, allowing us to hear sounds from different sources, such as musical instruments or voices. The intensity and frequency of sound waves determine the loudness and pitch of the sound we hear. Sound waves can be measured in decibels (dB) for loudness and hertz (Hz) for frequency. Understanding sound energy is essential in fields like music, acoustics, and engineering.
