Guide to Audiometry: Masking, Cross-Hearing, and
Threshold Testing Questions With Complete Solutions
normal tympanic membrane
can see right through it. can see malleus, no liquid on the other
side, and cone of light
otitis media
ear infection, fluid filled middle ear space (can cause pressure
and swelling of TM)
cerumen build up
excessive amount of wax in the ear canal could impede sound
from getting through
perforated ear drum
if the ear drum cannot vibrate, you will have a conductive loss
otosclerosis
bones of middle ear have become soft and spongy
sensory/neural hearing loss
damage to inner and hearing nerve. occurs when hair cells
(organ of corti) are damaged
mixed hearing loss
problems occurring in both the conductive and sensory/neural
mechanisms
, hearing by AC is impaired but hearing by bone conduction is
normal
conductive
hearing loss that exists which there is the same amount of
attenuation for both AC and BC
sensorineural
results reveal both a loss in hearing sensitivity by BC and AC,
but there is a greater AC loss
mixed
peripheral auditory pathways
outer, middle, inner
central auditory pathways
auditory centers in brain stem
auditory processing disorder
not dependent upon language abilities and cognitive abilities;
usually happens without conductive hearing loss and
sensory/neural pathways
erroneous hearing loss
tests show some degree of hearing loss but have normal hearing
or insufficient auditory pathology to explain extent of loss
malingering
faking the problem
psychogenic hearing loss
