Video Summary

To verify a hearing aid is performing to standards, first remove it from the client and save any wearer settings if needed. Reconfigure the device to test settings in the programming software, then place it correctly in the test box and coupler. Use the reference microphone positioned near the hearing aid microphone. Run ANSI measurements at full-on gain and reference test gain to check outputs like max OSPL90, average gain, frequency range, and distortion. Compare results with the manufacturer’s data sheet, then restore the original settings afterward.
