Hearing (or audition) is the sense of detecting sound, that is, receiving information about the environment from vibratory movement communicated through a medium such as air, water, or ground. It is one of the traditional five senses, along with sight, touch, smell, and taste.Both vertebrates and arthropods have a sense of hearing. In humans and other vertebrates, hearing is performed primarily by the auditory system: Sound is detected by the ear and transduced into nerve impulses that are perceived by the brain.
