HEARING AID DISPENSER PRACTICE TEST QUESTIONS & ANSWERS 100% CORRECT
|WELL UPDATED 2024/2025 EXAM |GRADED A+




Typanometry - ANSWER-What identifies a measure of of compliance of the TM (ear
drum)?



+200 H2O to -200 H2O - ANSWER-Typanograms probe tip measures from......



Type A Tympanogram - ANSWER-A (normal) Intact TM(ear drum). Requires the presents
of air in the middle ear, an intact ossicles, an normal Eustachian tube.



Type Ad Tympanogram(deep) - ANSWER-Intact TM, normal Eustachian tube function,
energy flow is reduced. 1). Ossicular discontinuity (incomplete chain) flaccid movement
of the membrane, or 2). a Monomeric membrane(behind the membrane).



Type B Tympanogram - ANSWER-A canal obstruction, TM perforation, middle ear
fluid(includes possible fluids from infection ,blood [from trama]. Also possible improper
insertion of probe tip could give a false positive.



Type C Typanogram - ANSWER-The same as type B, but also shows substantial negative
pressure in the middle ear space. Patient feels "fullness" or "hollowness", and
decreased hearing. Requires medical referral.



3000, 4000, and 6000 Htz - ANSWER-Individuals with noise induced hearing loss have a
"V Notch at.....

,Interaural intenuation - ANSWER-The loss of sound energy as it travels from the test ear
to the non-test ear.



1000 Htz - ANSWER-Bone conduction testing begins at what frequency?



Pure tone threshold testing means: - ANSWER-The lowest intensity sound a patient
hears 50% of the time.



Excessive ambient noises - ANSWER-What are greater for the lower frequencies than
the higher frequencies?



It is easier to hear when a sound stops than when it begins. - ANSWER-The descending
technique is preferred because:



Air Bone Gap - ANSWER-Name the difference in the bone conduction and the air
conduction.



The Air-Bone Gap is: - ANSWER-Always better better hearing by bone conduction than
by air conduction, never the reverse.



The Air-Bone Gap indicates: - ANSWER-Impairment to the conductive portion of the
hearing mechanism.



Hear well equally at all frequencies. - ANSWER-The human ear can NOT:



the Dynamic Range. - ANSWER-The intensity range is



125 to 8000 Hz. - ANSWER-The range of frequencies that help people achieve better
communication is

,Audiometry - ANSWER-A procedure that measures the sensitivity of a person's hearing
retaliative to normal hearing.



Depending on the instructions: - ANSWER-The results obtained can differ by as much as
10 dB.



40 dB HL. (1000 Hz) - ANSWER-Start Air Conduction testing at:



Descending technique: - ANSWER-Gradually decrease the the tone by 10 dB steps until
the tone is heard.



Ascending technique: - ANSWER-Gradually increase the the tone by 5 dB steps until the
tone is heard again.



Rule of thumb: - ANSWER-Decrease by 10 dB, Increase by 5 dB.



0 dB HL: - ANSWER-Normal ears hear at all frequencies.



0-20 dB HL: - ANSWER-Normal range



21-40 dB HL: - ANSWER-Mild Hearing Loss



41-70 dB - ANSWER-Moderate Loss



71-90 dB HL: - ANSWER-Severe Loss



91 dB HL Plus: - ANSWER-Profound Loss

, 1000 Hz, 2000 Hz, 4000 Hz, 8000 Hz, 1000 Hz, 500 Hz, 250 Hz, 125 Hz - ANSWER-What
is the order of Presentation for Air Conduction testing?



750 Hz and 1500 Hz - ANSWER-What are the intermediate frequencies to be tested?



Sensation Level - ANSWER-What is the actual presentation intensity, minus the
patient's threshold level?



Mirror Audiogram (or Shadow Curve) - ANSWER-When the tone is loud enough to be
heard by the better ear before the poorer ear threshold can be found is called



40 dB - ANSWER-Interaural Intenuation (IA) for pure tone air conduction testing is:



Tone Decay Tests - ANSWER-What test measures Auditory Fatigue of the VII cranial
nerve. (Given at 4000 Hz @ 20dB HL for one minute)?



Difficulty understanding speech, tinnitus, and vertigo. - ANSWER-Auditory Fatigue
symptoms:



Bone conduction testing - ANSWER-What type of test bypasses the outer and middle
ear?



Bone conduction tests - ANSWER-What test shows the possible results of the
improvement in the patients hearing without the use of a medical instrument., and may
also show a mixed loss?



Sensorineural Loss Thresholds - ANSWER-What outcome indicates the same for both
air and bone conduction testing? Never the reverse.



Bone Conduction Testing - ANSWER-What type of test shows the threshold of the
cochlea directly?
