Selecting the correct dome size
Each Lexie hearing aid comes with three different types of domes,
namely; open domes, double domes and tulip domes. Lexie hearing
aid domes are made out of a soft rubber material and attach to
the end of the slim tube. Open domes come in three sizes - small,
medium and large. Double domes come in two sizes - medium and
large.
Your Lexie hearing aid comes pre-assembled with a tulip dome,
which has one standard size. This dome should be used to complete
the Lexie Hearing Check, as its flexibility allows it to fit into many
differently sized ear canals.
Once you have completed the hearing check and your hearing aid
has been set to your unique hearing profile, you may try different
dome types and sizes, if necessary. Try the different sizes of that
dome type to find the most comfortable fit for your ear canal. The
dome should fit snugly in the ear canal opening, so that the ear canal
is properly sealed. In other words, the dome shouldn’t feel like it is
falling out of the ear or that it has to be squeezed or forced into
the ear.
