All behind-the-ear hearing aids have a
microphone, amplifiers and processors, a
volume control, a tone hook, an ear mold, an
on/off switch, and a battery compartment.
Sound enters the microphone, is amplified
and shaped by the processor, and is directed
out the tone hook and through the earmold
into your child's ear. The earmold is
specifically molded to the shape of your
child's ear. Earmolds need to be
replaced fairly often as your child's ear
grows. |
