How we hear
An electronic device usually worn by a person for amplifying sound before it reaches the receptor organs
What is a hearing aid
malleus, incus, stapes
Ossicles of the middle ear
contains nerves for hearing
What is the cochlea
outer ear, middle ear, inner ear
Parts of the ear
is often used to describe people with any degree of hearing loss, from mild to profound, including those who are deaf and those who are hard of hearing.
Hearing impaired
the vibration of sound waves on the eardrums and the firing of electrochemical impulses in the brain
What is hearing
What are the tiny bones that make up the middle ear?
Hammer, Anvil, and Stirrup
How many bones make up the ear?
The part of the ear that collects sound waves; consists of the pinna, the ear canal, and the eardrum.
What is the outer ear
contains receptors for balance
vestibule and semicircular canals
loss of ability to detect pure tones in decibels >20db
What is hearing loss
connects the middle ear with the nasopharynx and allows passage of air
What is the Eustachian tube
one who studies and specializes in hearing
audiologist
contains cochlea, semicircular canals, and vestibular sacs
What is the inner ear
combination of conductive, sensory, and neural hearing loss
mixed hearing impairment
The external, visible part of the ear.
What is the pinna
Happy Wednesday
Free Points
A hearing impairment, usually mild, resulting from malfunctioning along the conductive pathway of the ear (i.e., the outer or middle ear).
Conductive hearing impairment
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
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 brain for interpretation of sound
How does hearing occur?
transmits sound waves from the pinna to the tympanic membrane of the middle ear
What is the external auditory canal
a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
cochlear implant
occurs when the inner ear nerves and hair cells are damaged
sensorineural hearing impairment
Is the eardrum. Divides the external ear from the middle ear.
What is the tympanic membrane
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.
