HAC Pediatric Hearing Aid Fitting 3

Question 1

Which earmold material is generally preferred for active infants and toddlers due to safety and flexibility?

Accepted Answer

Soft silicone

Answer

Soft silicone earmolds are safer and more comfortable for young children, reducing injury risk and improving retention.

Question 2

How often should earmolds typically be remade for rapidly growing infants in the first year of life?

Accepted Answer

Every 3–4 months

Answer

Infant ear canals grow rapidly, so earmolds may need replacement every 3–4 months to maintain a proper acoustic seal and prevent feedback.

Question 3

A child with a unilateral mild-to-moderate hearing loss in one ear and normal hearing in the other is best served by:

Accepted Answer

A single hearing aid on the impaired ear

Answer

A single hearing aid on the impaired ear helps restore binaural hearing advantages and supports speech and language development.

Question 4

During a pediatric hearing aid orientation, which topic is LEAST relevant to cover with parents?

Accepted Answer

Insurance billing codes used by the audiologist

Answer

Insurance billing codes are administrative details that parents do not need to understand to successfully manage their child's hearing aids.

Question 5

What does the term 'audibility index' (AI) or 'speech intelligibility index' (SII) measure in pediatric fittings?

Accepted Answer

The proportion of the long-term average speech spectrum audible to the child

Answer

The SII quantifies how much of the speech signal is audible, helping audiologists verify that amplification targets are met.
