Sound energy is a form of energy that is produced by vibrating objects. These vibrations create sound waves that travel through a medium (like air, water, or solids) to reach our ears. When these waves hit our eardrums, our brains interpret them as sound. Different sounds have different frequencies and amplitudes, which we perceive as pitch and loudness.
