Hearing Aid Dispenser UPDATED Exam
Questions and CORECT Answers
Typanometry - CORRECT ANSWER - What identifies a measure of of compliance of the
TM (ear drum)?
+200 H2O to -200 H2O - CORRECT ANSWER - Typanograms probe tip measures
from......
Type A Tympanogram - CORRECT ANSWER - A (normal) Intact TM(ear drum).
Requires the presents of air in the middle ear, an intact ossicles, an normal Eustachian tube.
Type As Typanogram(shallow). - CORRECT ANSWER - Transfer of energy is stiffened.
Stiffened movement of the TM. Ossicular fixation, compliance is reduced,
typanosclerossis(calcium deposits of the TM). CONDUCTIVE HEARING LOSS problem.
Type Ad Tympanogram(deep) - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER - Individuals with noise induced
hearing loss have a "V Notch at.....
,Interaural intenuation - CORRECT ANSWER - The loss of sound energy as it travels from
the test ear to the non-test ear.
1000 Htz - CORRECT ANSWER - Bone conduction testing begins at what frequency?
Pure tone threshold testing means: - CORRECT ANSWER - The lowest intensity sound a
patient hears 50% of the time.
Excessive ambient noises - CORRECT 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. - CORRECT ANSWER - The
descending technique is preferred because:
Air Bone Gap - CORRECT ANSWER - Name the difference in the bone conduction and
the air conduction.
The Air-Bone Gap is: - CORRECT ANSWER - Always better better hearing by bone
conduction than by air conduction, never the reverse.
The Air-Bone Gap indicates: - CORRECT ANSWER - Impairment to the conductive
portion of the hearing mechanism.
Hear well equally at all frequencies. - CORRECT ANSWER - The human ear can NOT:
the Dynamic Range. - CORRECT ANSWER - The intensity range is
125 to 8000 Hz. - CORRECT ANSWER - The range of frequencies that help people
achieve better communication is
,Audiometry - CORRECT ANSWER - A procedure that measures the sensitivity of a
person's hearing retaliative to normal hearing.
Depending on the instructions: - CORRECT ANSWER - The results obtained can differ
by as much as 10 dB.
40 dB HL. (1000 Hz) - CORRECT ANSWER - Start Air Conduction testing at:
Descending technique: - CORRECT ANSWER - Gradually decrease the the tone by 10 dB
steps until the tone is heard.
Ascending technique: - CORRECT ANSWER - Gradually increase the the tone by 5 dB
steps until the tone is heard again.
Rule of thumb: - CORRECT ANSWER - Decrease by 10 dB, Increase by 5 dB.
0 dB HL: - CORRECT ANSWER - Normal ears hear at all frequencies.
0-20 dB HL: - CORRECT ANSWER - Normal range
21-40 dB HL: - CORRECT ANSWER - Mild Hearing Loss
41-70 dB - CORRECT ANSWER - Moderate Loss
71-90 dB HL: - CORRECT ANSWER - Severe Loss
91 dB HL Plus: - CORRECT ANSWER - Profound Loss
, 1000 Hz, 2000 Hz, 4000 Hz, 8000 Hz, 1000 Hz, 500 Hz, 250 Hz, 125 Hz - CORRECT
ANSWER - What is the order of Presentation for Air Conduction testing?
750 Hz and 1500 Hz - CORRECT ANSWER - What are the intermediate frequencies to be
tested?
Sensation Level - CORRECT ANSWER - What is the actual presentation intensity, minus
the patient's threshold level?
Mirror Audiogram (or Shadow Curve) - CORRECT 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 - CORRECT ANSWER - Interaural Intenuation (IA) for pure tone air conduction
testing is:
Tone Decay Tests - CORRECT 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. - CORRECT ANSWER - Auditory
Fatigue symptoms:
Bone conduction testing - CORRECT ANSWER - What type of test bypasses the outer
and middle ear?
Bone conduction tests - CORRECT 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 - CORRECT ANSWER - What outcome indicates the
same for both air and bone conduction testing? Never the reverse.
