Measurement Tool for Thin Tubes and Receiver Links

To ensure a comfortable and secure hearing aid fit, the proper length for the Thin Tubes and Receiver Links must be selected. Use the HearSource Measurement Tool to find the right tube length for you. When ordering your HearSource hearing aids we will use this
number to fit you with the right size receiver link.

Easy Measurement Tool Instructions

You will need: a printer, scissors, and someone to help you.

  4. Hold your head level (as you normally would).
  5. Have another person make sure the top white line is on top of your ear, behind your earlobe.
  6. Have them look and tell you the number closest to the top of your ear canal (the TOP, not the middle).

  7. Write down this number if they are both the same. If your ears are different, be sure to note which ear was which number!


HearSource Thin Tubes

Our HearSource OpenEar hearing aid thin tubes use a number scale from zero (0B), the shortest, to three (3B), the longest.

Receiver Links

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), the longest.
