A graphic representation of the relation of vibration frequency and the minimum sound intensity for hearing.
An electrical prosthetic device that enables individuals with sensorineural hearing loss to recognize some sounds and that consists of an external microphone and speech processor that receive and convert sound waves into electrical signals which are transmitted to one or more electrodes implanted in the cochlea where they stimulate the auditory nerve.
Conductive Hearing Loss
Hearing loss or impairment resulting from interference with the transmission of sound waves to the cochlea.
An electronic device usually worn by a person for amplifying sound before it reaches the receptor organs.
The essential part of the vertebrate organ of hearing and equilibrium that includes the vestibule, the semicircular canals, and the cochlea.
The intermediate portion of the ear containing a chain of three ossicles that extends from the tympanic membrane to the oval window and transmits vibrations to the inner ear.
The outer visible portion of the ear that collects and directs sound waves toward the tympanic membrane by way of a canal which extends inward through the temporal bone.
Sensorineural Hearing Loss
Hearing loss or impairment resulting from problems with the auditory nerves.
Mechanical energy that is transmitted by longitudinal pressure waves in a medium (such as water or air).
the external part of the ear in humans and other mammals
transmits sound from the pinna to the eardrum
Lateral bone in the middle ear responsible for assisting in transmission of vibrations
the middle bone in the middle ear responsible for assisting in transmission of vibrations
most medial middle ear bone responsible for assisting in transmission of vibrations
transforms vibrations from sound waves into electrical impulses
bundle of nerve fibres that carry information between the cochlea in the inner ear and the brain
membrane which vibrates in response to sound waves and is located between the outer and middle ear
inferior cranial nerve that conveys sensory impulses from the organs of hearing and balance in the inner ear to the brain
superior cranial nerve that conveys sensory impulses from the organs of hearing and balance in the inner ear to the brain
an oval opening at the head of the cochlea, connecting the middle and inner ear, through which sound vibrations of the stapes are transmitted
central part of the bony labyrinth in the inner ear, and is situated medial to the eardrum, behind the cochlea, and in front of the semicircular canals.
auditory tube or pharyngotympanic tube, is a tube that links the nasopharynx to the middle ear
