Auditory physiology is the study of how the human body processes sound. It involves the ear's structure, including the outer ear, middle ear, and inner ear, which work together to capture and transmit sound waves. The cochlea, located in the inner ear, converts these sound waves into electrical signals that the brain can interpret. Once the cochlea sends signals through the auditory nerve, they travel to the auditory cortex in the brain. Here, the brain analyzes the signals, allowing us to perceive different sounds, such as speech and music. This complex process enables us to communicate and interact with our environment effectively.
