Choosing the correct slim tube HE length will ensure a
more accurate, comfortable fit. The measurement tool
included in the kit allows for a quick and simple
measurement and has the following features:
Color Code Markings
– blue (left
ear) and red (right ear) color code
markings to indicate which of the
client’s ears to measure.
Horizontal Line Markings
– measurements must be made
horizontally with the measurement tool touching the skin
in the gap between the head and the top of the pinna.
Four Horizontal Sightlines
– (0-1-2-3) – to indicate which
tube length you should use for an accurate fitting.
To measure for an accurate slim tube HE length:
1. Place your head at the
same horizontal level as
the client’s head so you
are looking straight into
the client’s ear that you
wish to fit with the hearing instrument.
2. Hold the measurement tool with the
appropriate blue or red color code
marking (for the left or right ear) with
your thumb placed on the ear diagram.
3. Place the measurement tool on the
top of the ear and in contact with the
skin in the narrow gap between the
head and the pinna. Keep the
horizontal line on the measurement
tool horizontal and level.
4. Choose the sightline (0-1-2-3) on the
measurement tool that is most parallel
with the top of the opening of the ear
canal. In this example, the sightline
marked 1 would be the most accurate choice.
5. Make a note of the sightline chosen and then repeat
steps 1-4 on the opposite ear for a binaural fitting.
Note: It is important to measure the opposite ear for a
binaural fitting since right and left ear sizes can vary
and thus, require different slim tube HE lengths.
