Basic Audiology Exam 4
1. audiological test results = putting the puzzle together in order to
determine an accurate , plan, and
appropriate : diagnosis, treatment, referrals
2. calculating WDS:
HL should always be within normal range
use the AC thresholds at Hz and Hz and find average:
conductive 2000, 4000
3. word recognition scores in percentages:
%- % = normal limits
%- % = slight difficulty
%- % = moderate
%- % = poor
%- % = very poor: 90-
100 75-90
60-75
50-60
<50
4. cerumen impaction:
must have % blockage to result in a conductive hearing
loss the earwax will create between a - air/bone gap
if a significant amount of soft earwax is located by the opening the ear canal
should not be performed:
100 15-25
tympanometry
5. what disorder?
most in older adults (men), fullness, itching, pain, fluctuating hearing
loss, constant hearing loss, popping sound: 100% cerumen impaction
6. c

acoustic reflex =: conductive,
mixed 15-25 ABG
generally
flat normal
type B (small
PV) absent
8. treatment of cerumen impaction (individual or medical): ear drops, flush
out flush ear, ENT (suction)
9. otitis externa:
inflammation and infection in the
's ear
only causes a hearing loss when the ear canal becomes , resulting
in a - ABG: external ear canal
swimmer
completely swollen shut, 15-25
10. what disorder?
redness in ear canal, itching, pain, fluid drainage, odor, hearing loss
when swollen: otitis externa
11. otitis externa:
presents itself
prevention =
prognosis =: unilateral or bilateral
keep ear dry, don't overclean, wear
plugs good
