What is the transfer function of the ear?

The acoustic transfer function of an external ear means the transfer function from the sound at the entrance of the ear canal (or from the electrical input of a headphone or hearing aid coupled to the ear) to the sound at the eardrum.

What are the 4 main functions of the ear?

Your ears have two main functions: hearing and balance. Hearing: When sound waves enter your ear canal, your tympanic membrane (eardrum) vibrates. This vibration passes on to three tiny bones (ossicles) in your middle ear.

What type of energy is transferred to your ears?

Acoustic energy, in the form of sound waves, is channeled into the ear canal by the ear. Sound waves strike the eardrum, causing it to vibrate (like a drum) and changing the acoustic energy into mechanical energy.

How is energy transferred through the ear structures?

The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

What are the three main functions of the ear?

The human ear, like that of other mammals, contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear.

What are the functions of ear muscles?

The middle ear muscles (MEM) alter the mechanical properties of the middle ear and thus modulate the way sound vibrations are transmitted to the cochlea. Two muscles are involved in this reflex: the stapedius, which attaches to the neck of the stapes, and the tensor tympani, which attaches to the neck of the malleus.
