Practical Exam-Hearing Aid Dispenser Questions With
Solved Solutions Already Graded A+
Better sound localization, better hearing in background noise, the ability to focus
one sound over another, sounds appear louder, better peach comprehension.
List at least 3 advantages of Binaural Hearing over a monaural fitting:
1. Noise induced HL
2. Noise trauma
3. Presbycusis
4. Congenital HL
5. Syndromic HL (Waardenburg, Treacher Collins, Usher, and branchio-oto-renal)
6. Nonsyndromic HL
7. Sudden HL or sudden deafness
8. Meniere's Syndrome
9. Cranial Trauma
10. Ototoxic drugs
Causes of S/N hearing loss include:
A. reduced audibility and intelligibility
1. poor frequency selectivity
2. reduced dynamic range
3. SNHL elevates thresholds but tolerance for loud sounds is unchanged relative
to normal
B. Recruitment
1. an exaggerated perception of loud sounds (abnormal loudness growth)
2. Important to measure UCLs at multiple frequencies to accurately measure
dynamic range.

Obtaining accurate information to determine if a referral is required.
A. Medical
Determine:
1. Stroke, arthritis, nephropathy, dementia, Alzheimer's
2. Head injuries
3. Family history of hearing loss
, 4. Past surgeries
5. Checking for any of the RED FLAG CONDITIONS.
B. Otological
C Pharmacological
D. Previous amplification history
E. Patient attitudes and expectations.
What is the benefit of obtaining a PATIENT CASE HISTORY?
1. Visible congenital or traumatic deformity of the ear.
2. History of active drainage from the ear in the previous 90 days.
3. History of sudden or rapidly progressive hearing loss within the previous 90
days.
4. Acute or chronic dizziness.
5. Unilateral hearing loss of sudden or recent onset within the previous 90 days.
6. Audiometric air-bone gap equal to or greater than 15 decibels at 500 Hz, 1,000
Hz, and 2,000 Hz.
7. Visible evidence of significant cerumen accumulation or a foreign body in the
ear canal.
8. Pain or discomfort in the ear.
List the 8 red flag conditions
1. Proper bracing technique (hands and head move as one)
2.
3.
. Landmarks on the TM
. 4 quads of the TM
List the steps involved with otoscopic inspection of the ear
Five reasons to perform otoscopy. (purpose and conditions)
1. Reveal any medical conditions which require a medical referral.
2. Inspect ear canal. Wax, foreign objects, growths.
3. Inspect back of pinna for surgical scars, lesions, skin disorders.
4. Verify ear canal is clean and TM is healthy.
5. Note any unusual landmarks.
1. Otalgia-Pain
2. Otorrhoea-Discharge
3. Hearing Loss
4. Tinnitus
5. Vertigo
Five symptoms of ear disease
1. Disinfect work area
2. Check equipment for static, crackling, or distortion.
3. Sound check: Sweep all of the frequencies and intensity levels. Listen for any
anomalies.
4. Calibrate mic to the head set.
5. Speech calibrations.
Explain steps involved in daily biological check:
Recite instructions for A/C testing
