Choosing The Correct Dome
Your HearClear™ HCR3 is shipped with a variety of domes in
different sizes and styles. This allows you to select the dome
that provides you with maximum comfort and hearing.
Open Style Domes
Open domes have openings for sound
to pass through from outside of the
hearing aid. They are intended for people
with noticeable to moderate and high
frequency losses. These domes work great
for people that use lower volume settings
(because whistling may occur with higher
volumes). The openings allow some
natural sound to pass into your ear and
provide more ventilation.
Closed Domes
Closed domes provide a seal to the
ear canal which helps trap the sound
providing more volume. In this way
these domes most greatly benet those
who have trouble hearing low frequency
sounds. These domes can also help
eliminate feedback.
Helpful Tip: Try a closed or double magic dome to
avoid whistling and/or feedback when the volume is
at higher settings.
