Interpretation of Serial Number
Each hearing instrument has its own
unique number located on the exterior
of the hearing aid.
Blue writing or blue coloring denotes a
left hearing instrument. Red writing or red
coloring denotes a right hearing instrument.
The first two digits of the serial number
represent the year in which the instrument
was manufactured. The second two digits
of the serial number represent the month
in which the hearing instrument was
manufactured.
Hearing loss can be improved, in most
cases, through medicine, surgery, or with
hearing instruments. Hearing aids are the
most commonly chosen option.
Today's hearing instruments are quite
small in size and feature sophisticated
electronics that accommodate a wide
variety of hearing losses.
Nature gave us two ears for a reason and
since the majority of people who have a
hearing loss are affected in both ears, two
(binaural) hearing instruments are typically
recommended. Two hearing instruments
should provide these benefits:
■
Better overall sound quality when
compared to one hearing instrument
(“stereo sound”).
■
The ability to locate a sound source in
noisy and normal listening conditions.
■
Increased ability to understand speech
in noisy and normal listening conditions.
■
A sensation of balanced hearing.
Talk with your hearing healthcare provider
about what is best for you. Even the best
technology can’t do the work of two ears!
