Human Hearing
The Human Ear
Some highlights: Frequency range
The audible human hearing range is from 20 Hz to 20 kHz
Most people can comfortably hear between 1000Hz to 5500 Hz
The Outer Ear
The outer ear gathers sound and channels it into the auditory canal toward the middle ear
The Middle Ear
The middle ear consists of the eardrum and three small bones: the hammer, anvil and the stirrup
The eardrum vibrates when it encounters sound waves
The bones transmit and magnify the vibrations
Middle Ear
The Inner Ear
The inner ear contains the cochlea and the auditory nerve
Vibrations are transformed into electrical impulses in the cochlea
The cochlea sends the impulses through the auditory nerve to the brain
Inner Ear
Infection in the Middle Ear and location of the ear components
