The hair cells mechanically transmit energy
The endolymph (fluid) moves from incoming sound causing the movement of the
hair cells
It analyzes sound based on frequency and intensity and transmits that sound to
the brain
Without the middle ear, if sound reached the inner ear it would be
a. virtually nonexistent
b. so loud it would cause nerve damage
c. distorted in frequency
,d. impossible to interpret - ✔✔Virtually nonexistent
without the middle ear approx. 99.9% of sound would be reflected back to the
atmosphere because the impedance of the inner ear is so much greater than
that of the atmosphere
The middle ear amplifies sound by approximately 17 times
Which of the following is most likely to cause conductive hearing loss?
a. presbycusis
b. otitis media
c. noise exposure
d. birth trauma - ✔✔Otitis media
middle ear infection causes swelling and fluid buildup in the middle ear space
preventing sound to reach the inner ear
chronic infections cause cause damage to the ossicular chain as well
Which is most likely to cause sensorineural hearing loss?
,a. a foreign object
b. impacted cerumen
c. Meniere's disese
d. serous otitis media - ✔✔Meniere's disease
Fluctuating fluid buildup in the cochlea causes damages to the hair cells
typically resulting in a low frequency HL
Which is not a true statement of conductive and sensorineural hearing losses?
a. Conductive hearing losses are often reversible
b. sensorineural hearing losses are usually permanent
c. sensorineural hearing losses impair discrimination
d. conductive loss does not affect threshold level - ✔✔Conductive loss does
not affect threshold level
both conductive and SNHL impact threshold acuity
A person with a hearing loss who suffers from recruitment will have
, a. difference in thresholds between ears
b. less distance between audibility and uncomfortable loudness levels
c. more distance between audibility and uncomfortable loudness levels
d. overcompensation of the better ear for the more affected ear - ✔✔Less
distance in dB between the hearing threshold and uncomfortable loudness level
Which condition is most commonly associated with normal hearing?
hyperacusis
diplacusis
presbycusis
none of the above - ✔✔Hyperacusis
Often associated with normal hearing, and can result from paralysis of the facial
(VII) nerve which causes paralysis of the stapedius muscle!
diplacusis is hearing the same sounds at different frequencies between ears
presbycusis is age related hearing loss
