3.  The piece of plastic or other soft material molded to fit in
the ear is known as “EARMOLD”.
 “EARMOLD” delivers sound from BTE hearing aid.
 The impression is made of the empty part of the outer ear
and ear canal, by the audiologist or hearing aid dispenser by
using silicon impression material.

6. Canal ear molds are similar to dome-style ear molds. They're made
from the canal portion of the impression, and are designed to be
inconspicuous, while providing good ear retention and a customized
fit.
 Canal molds require a relatively long ear canal to fit properly. No
portion extends into the concha bowl—they're completely
contained within the canal.

7.  Full-shell ear molds provide maximum ear retention,
and are sculpted by the lab for a natural appearance.
Full shells help prevent feedback, full shells work well
for moderate to severe hearing loss.

8.  Semi-skeleton ear molds are skeleton ear molds without
the back ring. Semi-skeleton molds work for people with
limited dexterity. Skeleton and semi-skeleton molds are
generally comfortable, easy to retain, and suitable for
people with mild to severe hearing loss.

9.  Half-shell ear molds are sculpted like full shell molds,
except the material is cut back to cover only the bottom
half of the concha bowl. Patients need adequate ear-
retention. Half shells are recommended for milder
hearing loss.

11.  Skeleton ear molds have material removed from the
center to enhance cosmetic appearance while still
providing excellent in-ear retention. Designed for
maximum comfort, a rim of material secures the mold
within the concha, creating an effective seal.
