Hearing
loss of ability to detect pure tones in decibels >20db
What is hearing loss
contains cochlea, semicircular canals, and vestibular sacs
What is the inner ear
the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window
What is the middle ear
occurs when the inner ear nerves and hair cells are damaged
What is sensorineural hearing impairment
An electronic device usually worn by a person for amplifying sound before it reaches the receptor organs
What is a hearing aid
the vibration of sound waves on the eardrums and the firing of electrochemical impulses in the brain
Hearing
The part of the ear that collects sound waves; consists of the pinna, the ear canal, and the eardrum.
What is the outer ear
one who studies and specializes in hearing
What is an audiologist
What transmits sound waves from the pinna to the tympanic membrane of the middle ear
External auditory canal
This is the long tunnel that connects to the pinna. It has ear wax and hair.
Ear Canal

Double the points
The external, visible part of the ear.
What is the Pinna
contains nerves for hearing
What is the cochlea
combination of conductive, sensory, and neural hearing loss
What is mixed hearing impairment

Parts of the middle ear
Anvil, Hammer, stirrup
Is the eardrum. Divides the external ear from the middle ear.
What is the tympanic membrane
What canals contain receptors for balance
Vestibule and Semicircular
How many tiny bones are in your ear?
Three
What connects the middle ear with the nasopharynx and allows passage of air
Eustachian tube
Canals that loop around your inner ear contain fluid and tiny hair like sensors that help you maintain a sense of balance. The fluid moves up and down, letting your brain know which direction you're facing.
how does the ear affect balance?
What makes the ossicles of the middle ear
malleus, incus, stapes
How does hearing occur?
- Sound is transmitted through the external auditory cannel to the TM
- Vibrations of the TM are transmitted by the middle ear bones to the oval window
- From here, sound is transmitted to the sensory organs of the inner ear where the round window disperses the vibrations
- Lastly, vibrations are converted to nerve impulses which are conducted by the 8th cranial nerve to the temporal lobe of the b
A hearing impairment, usually mild, resulting from malfunctioning along the conductive pathway of the ear
