AP PSYCHOLOGY

Detailed explanation-1: -Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium.

Detailed explanation-2: -The sense of hearing is also known as AUDITION. Sound travels in waves and aspects of these waves determine the sound we hear. FREQUENCY–(number of waves per second) determines the PITCH. Amplitude or STRENGTH–(height of the wave) determines the LOUDNESS.

Detailed explanation-3: -What is hearing? Hearing refers to the awareness of the presence of sounds and placing meaning to that sound. It begins as vibrations that travel through your ear (outer ear, middle ear, and inner ear) through your nerves to your brain – where you hear.

Detailed explanation-4: -Tiny hair cells inside the cochlea, the sensory organ of the ear, convert these vibrations into electric impulses that are picked up by the auditory nerve. At birth, each typical ear has about 12, 000 sensory cells, called hair cells, which sit on a membrane that vibrates in response to incoming sound.

Detailed explanation-5: -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.
