HAC Pediatric Hearing Aid Fitting 2 — Questions and Answers
Question 1: Which verification method is considered the gold standard for confirming hearing aid output in infants and toddlers?
- Functional gain measurement
- Real-ear-to-coupler difference (RECD) (Correct answer)
- Sound field audiometry
- Parent questionnaire
Correct answer: Real-ear-to-coupler difference (RECD)
RECD accounts for the smaller ear canal volume of young children, allowing accurate prediction of real-ear output from coupler measurements.
Question 2: A 6-month-old is fitted with hearing aids. Which prescription method is most appropriate for this age group?
- NAL-NL2
- DSL v5.0 Child (Correct answer)
- FIG6
- NAL-R
Correct answer: DSL v5.0 Child
DSL v5.0 Child is specifically designed for pediatric fittings, targeting audibility across the speech spectrum for developing listeners.
Question 3: What is the primary purpose of a pediatric hearing aid loaner program?
- To reduce cost of new devices
- To ensure continuity of amplification during repair or loss (Correct answer)
- To trial multiple styles before purchase
- To provide aids for school use only
Correct answer: To ensure continuity of amplification during repair or loss
Loaner programs prevent gaps in auditory access, which are critical during sensitive periods of speech and language development.
Question 4: When measuring RECD in a young child who cannot tolerate foam tip insertion, the best alternative is to:
- Use age-based RECD averages from normative data (Correct answer)
- Skip RECD and use only coupler measurements
- Perform functional gain in a sound booth
- Rely on parental report of sound quality
Correct answer: Use age-based RECD averages from normative data
Age-based average RECD values from published normative databases can substitute when direct measurement is not feasible.
Question 5: Which hearing aid feature is most critical for a child in a noisy classroom environment?
- Extended low-frequency response
- Directional microphone technology (Correct answer)
- Cosmetic design
- Large battery size for extended life
Correct answer: Directional microphone technology
Directional microphones improve signal-to-noise ratio by focusing on sounds from the front, benefiting children listening to a teacher.
Question 6: At what age is it generally appropriate to begin open-ear or thin-tube BTE fittings in children?
- Birth to 6 months
- 6 to 12 months
- School age (5+) when ear canals are larger (Correct answer)
- Any age if ear canal size allows
Correct answer: School age (5+) when ear canals are larger
Open-fit BTEs are typically better suited to school-age children because younger children's ear canals are too small and the fittings are less secure.
Question 7: Which professional is primarily responsible for programming a child's hearing aids to prescriptive targets?
- Pediatrician
- Audiologist (Correct answer)
- Speech-language pathologist
- Otolaryngologist
Correct answer: Audiologist
Audiologists are trained to measure hearing, select, program, and verify hearing aids using prescriptive methods.
