HAC HAC Earmold Selection & Hearing Aid Styles 1

Question 1

Which hearing aid style fits entirely within the ear canal with no component visible outside the ear?

Accepted Answer

CIC (completely-in-canal)

Answer

A CIC hearing aid fits completely within the ear canal, making it the least visible of the traditional custom hearing aid styles.

Question 2

What range of hearing loss can a BTE hearing aid typically accommodate?

Accepted Answer

Mild to profound hearing loss

Answer

BTE hearing aids paired with appropriate earmolds can be fitted with varying receiver powers, accommodating hearing loss from mild through profound.

Question 3

Why is a BTE hearing aid with an earmold the preferred style for fitting children?

Accepted Answer

Only the earmold needs to be remade as the child's ear grows, not the entire device

Answer

Because children's ear canals grow rapidly, BTE fittings allow clinicians to simply refit the earmold as the ear changes without replacing the expensive hearing aid body.

Question 4

How does an ITC (in-the-canal) hearing aid differ from a CIC?

Accepted Answer

An ITC fits partly in the canal with a small portion visible in the concha bowl, making it slightly larger than a CIC

Answer

An ITC hearing aid is larger than a CIC, occupying part of the concha as well as the canal, offering easier handling and space for directional microphones.

Question 5

What is the primary benefit of an IIC (invisible-in-canal) hearing aid?

Accepted Answer

Maximum cosmetic discretion — it is not visible when the user is wearing it

Answer

The IIC sits at the second bend of the ear canal, placing it completely out of sight for an outside observer and providing the highest degree of cosmetic appeal.
