Which earmold design retains a locking extension while removing part of the rim?

• A. Semi Skeleton
• B. Skeleton
• C. Shell
• D. Half Shell

Answer: (A)

The semi skeleton earmold design is characterized by its structure that retains a locking extension while removing part of the rim. This feature allows the mold to be lightweight and more comfortable while still providing a secure fit. The ergonomic design helps in maintaining proper positioning of the hearing aid component within the ear canal. This design is particularly advantageous for users who need a substantial fitting but prefer a mold that does not cover the entire ear. It provides a balance between effectiveness in sound transmission and comfort, making it a popular choice among those who wear hearing aids. In contrast, the other designs offer different levels of coverage and support, which do not specifically retain a locking extension in the same manner when part of the rim is removed.
