Understand How Hearing Works

Hearing depends on the persistence of sound waves. The sound waves travel more slowly than light waves do. Sound waves are created due to changes in pressure which are generated by vibrating molecules. There are three influences of sound waves; The timbre, pitch and loudness.. A human can hear sounds that range between 20 and 20,000 Hertz. Knowing the structure of the ear is important to understand how hearing works. There are three parts of the ear; the outer ear middle ear and inner ear.
