Verification of hearing aid fitting via REM Measurement

Real Ear Measurement (REM)?

REM measures the actual sound amplification inside the ear canal with the hearing aid in place. It takes into account how the ear's unique anatomy affects sound – something that cannot be predicted with audiograms and fitting software alone.

🛠️ How is REM performed?

• Preparation:

  • A thin measuring tube (probe) is carefully inserted into the ear canal, approximately 5 mm from the eardrum.

  • The hearing aid is then inserted into the ear, over the probe.

• Reference measurement (REUR – Real Ear Unaided Response):

  • Sound is measured in the ear canal without the hearing aid active – this provides a starting point.

• Measurement with hearing aid activated (REAR – Real Ear Aided Response):

  • A familiar sound is played through a speaker in front of the patient.

  • The system measures how much amplification the user actually receives in the ear.

• Comparison with target:

  • The results are compared to a target curve (e.g. NAL-NL2, DSL) based on the user's audiogram.

  • Adjustments are made in the hearing aid programming to match the target curve as accurately as possible.

✅ Why use REM?

• Provides individual customization – better than software-based adjustments alone

• Documents that the hearing aid provides the right help

• Reduces the number of readjustments and increases user satisfaction

• Ensures safe volume and protects against over-amplification
