How We Hear
Our ear is a complex organ comprised of three major sections: outer, middle and inner ear.
The outer ear (1) is responsible for collecting the sound and directing it to the eardrum which vibrates, sending the sound into the middle ear (2).
The resulting vibrations of the three little bones in the middle ear are transferred to the fluid inside the inner ear (3).
The specialized cells of the inner ear send signals to the brain where the sound is interpreted (4).
