Real-Ear Measurements 175
When the reference microphone is disabled, the analyzer uses the information
determined during the leveling process to determine the signal outside the ear
during the measurement. It is very important that the patient remain still after
leveling and that the sound field is undisturbed, particularly if the reference
microphone has been disabled.
to enable/disable the reference microphone:
1. Enter the Real-ear Insertion Gain or Real-ear SPL screen.
2. Press [MENU] to enter the local menu.
3. Select Reference Mic using [, ] under Measurements.
4. Use [, ] to choose ON or OFF.
5. Press [EXIT] to return to the measurement screen.
8.4.10 Viewing numerical curve data
The frequency response curves measured by the 8000 test system can be viewed
in either the standard graphical format or in data format, allowing the clinician to
take a look at the actual numerical values of the measurements.
to view curve data in the real-ear insertion Gain screen:
1. Enter the Real-ear Insertion Gain:
2. Press [MENU] to enter the local menu.
3. Select Data/Graph under Display using [, ].
4. Use [, ] to choose:
• AIDED DATA: To view selected aided curve.
• IG DATA: To view selected insertion gain curve.
• GRAPH: To view in standard graphical (non-numeric) format.
5. Press [EXIT] to return to the Insertion Gain screen. Instead of the measurement
graphs, you will now see tables of numerical data. See Figure 8.4.9.
6. Use [F2] to select the curve you want to view. Depending upon your selection
in Step 3, you will either see the insertion gain or the aided gain results.
