Practice Question Bank & Answer Rationale
THIS PACK CONTAINS
149 exam-style multiple-choice questions. Each question includes the correct answer and a complete
rationale for focused revision.
COVERAGE
This practice examination assesses entry-level competency for Connecticut hearing instrument specialist
licensure, covering audiometric interpretation, ear anatomy and pathology, hearing aid electroacoustics, fitting
and verification, Connecticut statutes and regulations, ethics, and patient management. Items mirror the rigor
and applied reasoning expected of accredited U.S. allied-health credentialing examinations.
STUDY GUIDE
Recommended duration: 2 hours. Passing target: 70% (35/50 correct).

,1. A patient's audiogram shows a 45 dB air-bone gap at 500 Hz with normal tympanometry
and intact acoustic reflexes. Which finding best explains this pattern?
[ ] A. Otosclerosis with stapes fixation
[ ] B. Sensory presbycusis
[ ] C. Noise-induced cochlear damage
[ ] D. Vestibular schwannoma
CORRECT: A. Otosclerosis with stapes fixation
A conductive gap with normal tympanometry and intact reflexes is classic for otosclerosis, where stapes
fixation stiffens the middle-ear system. Presbycusis and noise damage are sensorineural with no air-bone
gap, and vestibular schwannoma typically produces asymmetric sensorineural loss with abnormal reflex
findings.
2. Under Connecticut law, which action is required before a hearing instrument specialist
may dispense a hearing aid to a prospective patient?
[ ] A. Obtain a signed medical waiver or document physician clearance consistent with FDA and state
requirements
[ ] B. Perform a complete vestibular evaluation
[ ] C. Refer for cochlear implant candidacy screening
[ ] D. Obtain a CT scan of the temporal bone
CORRECT: A. Obtain a signed medical waiver or document physician clearance consistent with FDA
and state requirements
Federal FDA rules and Connecticut statutes require that a prospective user either obtain a physician
evaluation within six months or sign a waiver, unless exempted. Vestibular testing, implant screening, and
imaging are not prerequisites for routine hearing aid dispensing.
3. A hearing aid's published OSPL90 is 118 dB SPL and its full-on gain is 55 dB. Which
interpretation is most accurate?
[ ] A. The aid can produce up to 118 dB SPL output regardless of input level
[ ] B. Maximum output is 118 dB SPL and maximum gain is 55 dB under the specified test conditions
[ ] C. The aid's average gain is 118 dB and peak gain is 55 dB
[ ] D. The aid's compression ratio is approximately 2:1
CORRECT: B. Maximum output is 118 dB SPL and maximum gain is 55 dB under the specified test
conditions
OSPL90 is the saturation output measured with 90 dB SPL input, and full-on gain is the maximum gain at the
reference test setting. The values describe output and gain limits, not compression ratio or average gain.

,4. Which probe-tube placement error would most likely cause an invalid real-ear
measurement?
[ ] A. Probe tube extending 2-3 mm past the earmold tip
[ ] B. Probe tube positioned flush with the earmold tip
[ ] C. Probe tube placed 5 mm beyond the earmold tip, near the tympanic membrane
[ ] D. Probe tube oriented laterally toward the pinna
CORRECT: C. Probe tube placed 5 mm beyond the earmold tip, near the tympanic membrane
The probe tube should extend 2-5 mm past the earmold tip but remain well away from the tympanic
membrane; placing it too deep can cause standing waves and invalid readings. Flush placement or lateral
orientation may also be problematic, but excessive depth is the classic error.
5. A patient reports that their behind-the-ear hearing aid whistles only when they chew or
turn their head. Which cause is most likely?
[ ] A. Acoustic feedback from a loose or worn earmold
[ ] B. Receiver failure
[ ] C. Low battery voltage
[ ] D. Incorrect compression settings
CORRECT: A. Acoustic feedback from a loose or worn earmold
Movement-induced feedback typically stems from an inadequate acoustic seal, often due to a loose, cracked,
or worn earmold or tubing. Receiver failure, low battery, and compression settings would not selectively
produce whistling during jaw or head movement.
6. Which counseling statement best reflects evidence-based expectations for a new
hearing aid user with mild-to-moderate sensorineural loss?
[ ] A. Hearing aids will restore normal hearing in all environments
[ ] B. Hearing aids will improve audibility and communication but require adaptation and realistic
expectations
[ ] C. Hearing aids eliminate the need for communication strategies
[ ] D. Hearing aids should be worn only in quiet settings
CORRECT: B. Hearing aids will improve audibility and communication but require adaptation and
realistic expectations
Best-practice counseling emphasizes improved audibility and function, not restoration of normal hearing, and
includes realistic expectations and communication strategies. The other options overpromise, discourage
consistent use, or ignore rehabilitation principles.

, 7. A patient's word recognition score is 92% at 40 dB HL in quiet but drops to 48% in
background noise. Which fitting strategy is most appropriate?
[ ] A. Directional microphones with noise reduction and SNR-improving features
[ ] B. Linear amplification with high gain
[ ] C. CROS fitting
[ ] D. Bone-anchored implant evaluation
CORRECT: A. Directional microphones with noise reduction and SNR-improving features
The pattern suggests good quiet performance but poor speech-in-noise ability, which is best addressed with
directional microphones, digital noise reduction, and SNR-enhancing technology. Linear gain, CROS, or
bone-anchored devices do not target this specific difficulty.
8. Which condition would most strongly warrant medical referral before hearing aid
fitting?
[ ] A. Bilateral symmetrical high-frequency hearing loss
[ ] B. Unilateral sudden hearing loss with tinnitus and vertigo
[ ] C. Long-standing noise-induced hearing loss
[ ] D. Presbycusis with normal tympanometry
CORRECT: B. Unilateral sudden hearing loss with tinnitus and vertigo
Sudden unilateral hearing loss with tinnitus and vertigo raises concern for retrocochlear or vascular pathology
and requires urgent medical evaluation. Stable symmetrical losses, chronic noise-induced loss, and
presbycusis are typically managed with amplification.
9. A hearing aid's attack and release times are set very fast. Which perceptual
consequence is most likely?
[ ] A. Improved speech clarity in quiet
[ ] B. Distortion of low-frequency vowel sounds and potential pumping artifacts
[ ] C. Increased maximum output
[ ] D. Reduced battery drain
CORRECT: B. Distortion of low-frequency vowel sounds and potential pumping artifacts
Very fast attack and release times can track and distort low-frequency voiced sounds, producing pumping or
breathing artifacts. They do not increase maximum output or reduce battery drain, and may not improve quiet
speech clarity.
10. Which statement about cerumen management by a Connecticut hearing instrument
specialist is most accurate?
[ ] A. Specialists may perform cerumen removal only within the scope permitted by state law and after
appropriate training
