hearing aids and earmolds are made from a "cast"
of the ear. The cast is referred to as an ear
impression. The audiologist or hearing aid
dispenser makes the ear impression in the
office. It takes about 10 to 15 minutes. The
audiologist places a special cotton or foam dam
in the ear canal to protect the eardrum, and
then a waxy material is placed in the ear canal.
When the material hardens (about 5 to 10 minutes
later) the wax cast, along with the dam are
removed from the ear canal. Often, the ear canal
will be "oily" after the impression is removed.
This is normal. The oil comes from the wax
material and prevents the wax material from
sticking to the skin. |

audiologist before the ear impression is
obtained if you are allergic to plastic or
dyes! |
