Selecting the Correct REM Probe Tube: A Guide

REM probe tube placement

Real-Ear Measurement (REM) plays a vital role in verifying hearing aid fittings, ensuring patients receive the precise amplification they need. One of the most common questions our mye3shop supplies team hears is: “Which probe tube is the right one for my real-ear measurement system?”

To help clinicians choose the right probe tube, here’s a breakdown of common tubes and the REM systems they are compatible with.

Tips for Selecting and Using REM Probe Tubes

  • Always verify machine compatibility before purchasing replacement tubes.
  • Inspect tubes for wear or damage before each session.
  • Keep a variety of tube types on hand if your clinic uses multiple REM systems.
  • When in doubt, speak to the manufacturer of your system directly to ensure you’re using the correct probe tube.

Signs You’re Using the Wrong REM Probe Tube

  • Calibration errors – Your system struggles to calibrate or gives error messages.
  • Loose or mismatched connector – Tube doesn’t fit securely, or handle color doesn’t match system specs.
  • System warnings – Your REM machine flags compatibility issues or fails to recognize the tube.
  • Inconsistent results – Measurements vary too much between sessions or patients.
  • Patient discomfort – Patients report pain or irritation during insertion.
  • Improper placement – Tube bends, kinks, or doesn’t reach the correct depth.
  • Low SPL readings – Sound pressure levels are lower than expected, affecting accuracy.
  • Tube damage – Tubes show wear, cracks, or deform easily.

Why the Right Probe Tube Matters

  1. Accuracy: Probe tube placement directly affects real-ear sound pressure level readings.
  2. Patient Comfort: Tubes that fit well and are compatible with your system minimize discomfort.
  3. System Compatibility: Different REM machines require specific tube lengths, diameters, and connectors.
  4. Consistency: Using the correct tube ensures reproducible results between sessions and across patients.

Choosing the right probe tube is a small but crucial part of achieving accurate real-ear measurements. By matching your tube to your REM system, you can improve fitting precision, patient comfort, and the reliability of your audiometric assessments.
