WebA sound wave is a pressure wave caused by an object vibrating in a medium, like air. These waves can be described by how fast they vibrate (frequency) and the magnitude of their vibrations (amplitude). When sound waves hit our ears, they stimulate microscopic hair cells that send nerve impulses to our brains.
