HearSource Measuring Tool for
OpenEar Tubing and Receiver Link Sizes
To ensure a comfortable and secure hearing aid fit, the proper
length for the OpenEar tube and Receiver Links must be selected.
The step-by-step instructions are available on this web page.
Our HearSource OpenEar hearing aid thin tubes use a number scale
from zero (0B), the shortest, to three (3B), the longest.
Below, you can see that this thin tube is marked as a "1B" size
Similar to the OpenEar tubing the Receiver Links that are used with
the Receiver-in-the-Canal Style hearing aids use a number system to
identify their length. The length starts at zero (#0), the shortest, to three ( # 3),
Use the HearSource Measurement Tool to find the number of length.
When ordering your HearSource hearing aids we will correlate this
number to the appropriate size receiver link.
The receiver link size number is located underneath the casing of the
receiver as shown in the image below.
Step 1. Print out the OpenEar Measuring Tools at 100% scale.
Step 2. Cut out the HearSource Measuring Tool
Step 3. Place the HearSource Measurement Tool over the ear. The red measurement tool is for the right ear and the blue measurement tool is for the left ear. Have another person look and see the number closest to the top of the ear canal opening. This number is used to select the length of open ear tubing or receiver links you will need.
The picture on the right is the left ear being measured by the HearSource Measurement Tool. To find the appropriate length locate the closest number to the top of the opening of the ear canal. In this image the #1 is the correct measurement.
