17.9 REM or S-REM mode

The Speechmap environment provides two hearing instrument verification options: REM (real-ear measurement) and S-REM (simulated REM). In REM mode, the stimulus is controlled by the REM reference microphone below the ear and SPL in the ear canal is measured by the probe microphone. In S-REM mode, levels measured in the 2cc coupler are converted to estimated ear canal levels using the RECD values (age-appropriate average, entered, or measured). In addition, the stimulus delivered to the hearing instrument microphone is modified to include average microphone location effects for the hearing instrument type indicated. The screen display for both modes is the same, showing SPL, measured or simulated, in the ear canal.

For REM mode, review 10: Real-Ear Measurement Setup,

For S-REM mode review 7.9: Calibration of HIT reference microphone, 7.11:

Coupling the hearing instrument, 7.12: Positioning the hearing instrument.

It is suggested that hearing instruments be preset in S-REM mode with fine tuning done in REM mode.

vHighlight and <PICK> [Mode] to toggle between REM and S-REM.

Note that REM mode should be used for vented or open fittings. Vent effects depend on the vent, the ear and the hearing aid settings.
