Hearing is a complex process. The ear consists of 3 parts:

• Outer Ear
• Middle Ear
• Inner Ear

These three parts work together to allow us to perceive sounds. The part called the shower ear or auricle collects sound waves and directs them to the ear canal. These sound waves vibrate the eardrum, which is located at the end of the ear canal. When the eardrum vibrates, it moves three small ossicles in the middle ear. The middle ear is a small, air-filled cavity containing ossicles called hammer-anvil-stirrup arranged in a chain. The hammer ossicle is attached to the eardrum, and the hammer is connected to the anvil, and the anvil is connected to the stirrup with very sensitive joints. With the movement of the membrane, these three ossicles move, amplify sound waves and transmit them to the inner ear. The third ossicle in the chain, the stapes, vibrates the fluid in the auditory part of the inner ear – the cochlea – and activates thousands of hair cells in the cochlea. Feathers convert movement energy into neural signals. These sound signals are transmitted to the brain via the auditory nerve and interpreted by the brain as sound.
