HAC HAC Earmold Selection & Hearing Aid Styles 1 — Questions and Answers
Question 1: Which hearing aid style fits entirely within the ear canal with no component visible outside the ear?
- BTE (behind-the-ear)
- ITE (in-the-ear)
- CIC (completely-in-canal) (Correct answer)
- RIC (receiver-in-canal)
Correct answer: CIC (completely-in-canal)
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?
- Mild hearing loss only
- Mild to profound hearing loss (Correct answer)
- Moderate to severe hearing loss only
- Profound hearing loss only
Correct answer: Mild to profound hearing loss
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?
- It offers the greatest cosmetic concealment
- Only the earmold needs to be remade as the child's ear grows, not the entire device (Correct answer)
- It has the lowest maximum output level
- It requires no audiological programming adjustments
Correct answer: Only the earmold needs to be remade as the child's ear grows, not the entire device
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?
- An ITC sits entirely behind the ear
- An ITC fits partly in the canal with a small portion visible in the concha bowl, making it slightly larger than a CIC (Correct answer)
- An ITC is implanted under the skin
- An ITC uses bone conduction instead of air conduction
Correct answer: An ITC fits partly in the canal with a small portion visible in the concha bowl, making it slightly larger than a CIC
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?
- Highest available output power
- Maximum cosmetic discretion — it is not visible when the user is wearing it (Correct answer)
- Easiest insertion and removal for all users
- Best performance in windy outdoor conditions
Correct answer: Maximum cosmetic discretion — it is not visible when the user is wearing it
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.
Question 6: Which hearing aid style uses a thin wire running from a BTE body to a receiver tip or dome placed in the ear canal?
- ITE (in-the-ear)
- CIC (completely-in-canal)
- RIC/RITE (receiver-in-canal / receiver-in-the-ear) (Correct answer)
- CROS
Correct answer: RIC/RITE (receiver-in-canal / receiver-in-the-ear)
RIC (receiver-in-canal) or RITE (receiver-in-the-ear) hearing aids separate the receiver from the BTE body, connecting them via a thin electrical wire to a canal tip or dome.
