168 FONIX 8000 Hearing Aid Analyzer
Most of the operations of the Real-ear SPL screen are identical to the operations of
the Insertion Gain screen. Therefore, most of the instructions found in this section
apply to measurements performed in both screens. Any differences between operations
in the two screens are noted.
To enter the Real-ear SPL screen, press [F2] from the Opening screen to enter the
Real-ear Navigation screen. Then press [F4].
Figure 8.4.2—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.
8.4.3 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 Realear
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 8.2.1 and 8.2.2.
2. Insert the probe tube into the patient’s ear canal. See Section 8.2.3.
3. Input the patient’s audiogram to generate a target, if desired. See Section 8.3.
4. Press [EXIT] in the Audiogram Entry screen to return to the Real-ear Navigation
screen.
