Play it by (outer/mid) ear
The three bones in the middle ear.
What are the malleus, incus and stapes
The unit for measurement of frequency
What are hertz (Hz)
Two reasons we brace when performing otoscopy.
Movement of patient, ear-cough reflex/Arnold's branch of the vagus nerve
The region of the basilar membrane tuned for low frequency sounds
What is the apex
The presence of an air bone gap indicates this type of hearing loss
What is conductive hearing loss
These are the two structures that the eustachian tube connects
What are nasopharynx and middle ear space?
The frequency range for human hearing
What is 20Hz-20,000Hz
The threshold searching technique coined by Hughston and Westlake
What is "down 10, up 5"
The end organ of hearing located in the scala media which contains the hair cells
What is the organ of corti
The configuration of hearing loss most commonly associated with aging.
What is sloping/high frequency?
This is the name for scarring seen on the TM secondary to repeat trauma (ie infections, tubes, etc)
What is tympanosclerosis?
This is how stiffness impacts an objects resonant frequency
What is: greater stiffness= higher pitch, less stiffness=lower pitch
Surgically implanted device that can be used for people with permanent conductive hearing losses. Often used for bilateral atresia.
What is a BAHA (bone-anchored hearing aid)
The point at which the scala vestibuli and scala tympani meet
What is the helicotrema
The symbol for left bone conduction (unmasked)
What is > (carrot open to the left)
The portion of the malleus that can be observed via otoscopy.
What is the manubrium
Low frequency sounds have _____ wavelengths that high frequency sounds, which allows them to move more easily around objects
What is longer
The most commonly worn style of hearing aid
What is a Receiver in the canal (RIC)
The nerve responsible for innervating the cochlea and semicircular canals
What is CN VIII (vestibulocochlear nerve)
The configuration of hearing loss where thresholds are better in the low and high frequencies and poorest in the middle frequencies.
What is a "cookie bite"
This is why the middle ear has to act as an amplifier
What is the impedance mismatch between the air in the middle ear and the fluid in the inner ear?
List 2 of the cues used for sound localization:
What are: Interaural level differences, interaural timing differences, and/or pinna effect
The test used to verify the programming of a hearing aid. Unfortunately it is not performed as often as it should be
What is real ear measures
The membrane into which the stereocilia of the hair cells are embedded
What is the tectorial membrane
The speech sounds someone with a high frequency hearing loss would be most likely to struggle to hear (list at least 3)
What are: s, sh, th, t, k, p, h,
