Introduction
This examination is designed to assess candidate readiness for the California Hearing Aid Dispenser licensure
exam. It measures both foundational knowledge and applied clinical skills necessary for safe and effective practice.
The test includes multiple‑choice questions and scenario‑based items that require critical thinking, regulatory
compliance, and ethical judgment. Emphasis is placed on real‑world application—selecting, fitting, verifying, and
following up with hearing aids in diverse adult populations. Each question includes a verified correct answer and a
concise rationale to support exam preparation. This document mirrors the structure, difficulty, and content
emphasis of the actual licensing examination.
,SECTION ONE: QUESTIONS 1–100
1
A 72‑year‑old patient reports that speech sounds “muffled” but loud sounds are uncomfortable. Which
audiometric configuration is most consistent with this description?
A. Flat conductive loss
B. High‑frequency sensorineural loss with normal low‑frequency thresholds
C. Severe‑to‑profound mixed loss
D. Mid‑frequency notch at 2000 Hz
🟢B
🔴 RATIONALE: High‑frequency sensorineural loss reduces clarity of consonants (speech sounds muffled) while
low‑frequency hearing may be normal, making loud low‑pitched sounds uncomfortable (recruitment). Flat
conductive loss typically reduces loudness evenly. Mixed loss implies both components. Mid‑frequency notch is
less common in age‑related loss.
2
Under California law, a patient’s medical evaluation for hearing aid candidacy must be signed by a physician
within what time frame before the hearing aid is dispensed?
A. 30 days
B. 3 months
C. 6 months
D. 12 months
,🟢C
🔴 RATIONALE: California Business and Professions Code § 3315 requires a medical evaluation signed by a
physician within the preceding six months, unless the patient signs a valid medical waiver for adults aged 18 or
older.
3
During real‑ear verification, you measure an aided Real‑Ear Aided Response (REAR) that is 8 dB below target in
the 4000 Hz region. The most appropriate first action is to:
A. Increase the high‑frequency gain in the hearing aid programming software
B. Verify probe tube placement and repeat the measurement
C. Switch to a smaller dome to reduce occlusion
D. Recommend a cochlear implant evaluation
🟢B
🔴 RATIONALE: Before changing settings, always verify measurement integrity. Probe tube depth (within 5 mm
of eardrum) and stability are common sources of error. Re‑measure before adjusting gain.
4
Which of the following is a valid medical waiver condition under California regulations for an adult?
A. The patient refuses to see a physician after being informed of the recommendation in writing
B. The patient has had a hearing test within the last 5 years
C. The patient’s spouse is a physician
D. The patient’s primary language is not English
🟢A
🔴 RATIONALE: A medical waiver is valid when the adult patient acknowledges in writing that a medical
evaluation is recommended but declines it. The dispenser must retain the signed waiver in the patient file.
, 5
A patient with an asymmetric sensorineural hearing loss (right ear: mild, left ear: moderate‑to‑severe) should be
referred to a physician for further evaluation. What is the most urgent concern?
A. Cerumen impaction
B. Retrocochlear pathology such as vestibular schwannoma
C. Eustachian tube dysfunction
D. Otitis media with effusion
🟢B
🔴 RATIONALE: Asymmetric sensorineural loss raises suspicion for retrocochlear tumor (e.g., acoustic neuroma).
Standard of care requires medical referral for imaging (MRI) to rule out pathology.
6
Which hearing aid style is most likely to produce the occlusion effect?
A. Receiver‑in‑the‑canal (RIC) with open dome
B. Completely‑in‑the‑canal (CIC) with deep fit
C. Behind‑the‑ear (BTE) with standard earmold and large vent
D. In‑the‑canal (ITC) with skeleton mold
🟢B
🔴 RATIONALE: The occlusion effect occurs when the ear canal is sealed, amplifying low‑frequency
self‑generated sounds (voice, footsteps). CIC devices deeply occlude the canal, producing the strongest
occlusion. Open domes reduce occlusion.
7
What is the maximum permissible output (MPO) for a hearing aid dispensing in California?
A. No legal limit; only FDA guidelines recommend 132 dB SPL
