Figure 6.4.2—Rear-ear SPL screen. The T curve represnts the patient’s thresholds, the L, M, and
H curves represent the NAL-NL1 targets. Curve 1 shows the unaided response. Curves 2, 3, and
4 show the aided response at 50, 65, and 80 dB SPL. The patient’s UCLs are just off the top of
the graph.
6.4.3 Measuring the Unaided Response (REUG/REUR)
The REUG/REUR is a measurement of the unaided response of the patient’s ear
canal. It can be measured in either the Real-ear Insertion Gain screen or the
Real-ear SPL screen, and any measurement performed in one of these screens
will be automatically displayed in the other screen.
To measure the unaided response:
1. Position the patient in front of the sound field speaker and place the earhook
and reference microphone on the ear. See Sections 6.2.1 and 6.2.2..
2. Insert the probe tube into the patient’s ear canal. See Section 6.2.3.
3. Input the patient’s audiogram to generate a target, if desired. See Section
6.3.
4. Press [EXIT] in the Audiogram Entry screen to return to the Real-ear
Navigation screen.
