Hearing begins when sound waves enter the ear. The auditory nerve carries these signals to the brain. The brain then interprets these signals as sounds. The eight steps of hearing are:
1.Sounds enter the ear canal. 2.The eardrum vibrates. 3.The ossicles amplify the vibrations. 4.The cochlea senses the vibrations. 5.The auditory nerve transmits the vibration to the cochlear nucleus. 6.The cochlear nucleus sends the signal to the thalamus. 7.The thalamus sends signals to the cortex. 8.The cortex processes the signal.
