FONIX 7000 Hearing Aid Analyzer
3. For ANSI 87 and ANSI 96, set AGC aids to achieve the greatest possible
compression or as otherwise specified by the manufacturer. For ANSI 03, set
AGC aids to have the most minimum compression possible or as otherwise
specified by the manufacturer.
4. Put the hearing aid in “test mode,” if applicable. All noise suppression and
feedback cancellation features should be turned off.
5. Set the gain control of the aid to the full-on position.
6. Set the aid up in the sound chamber as described in Section 3.3.
5.1.3 Setting up the analyzer for ANSI
1. Press [F3] in the Opening screen to enter the ANSI S3.22 selection screen
2. Press [F1] to select ANSI 87, [F2] to select ANSI 96, or [F3] to select ANSI
03. The operation of these three tests is very similar.
2. Use [F1] to select LEFT or RIGHT ear.
3. Use [F2] to select the aid type: LINEAR, AGC, or ADAPTIVE AGC. (Press
[F2]. Use [∨, ∧] to choose the selection. Press [>] to complete the selection
and close the pop-up menu.)
4. Use [F3] to select the full-on gain (FOG) amplitude used in the test
sequence. We recommend setting this to AUTO, which will automatically
use the appropriate amplitude. This step does not apply for ANSI 03.
5. Use [F5] to select whether or not to perform a telecoil measurement.
6. Press [MENU] to enter the local menu and make any desired selections. See
Section 5.1.9.
Use [F7] to return all ANSI settings to their power-on default conditions.
Use [F8] to display all selected ANSI settings.
5.1.4 Running an ANSI 96 or an ANSI 03 Test
After leveling the sound chamber as described in Section 5.1.1, setting up the
aid as described in Section 5.1.2, and setting up the analyzer as described in
Section 5.1.3, follow these instructions:
1. Press [START] to begin the test. Usually the 7000 test system will pause
during the measurement process in order to let you adjust the gain of the
hearing aid to the reference test position.
a. Lift the sound chamber lid and adjust the gain control of the aid until the
RTG MEASURED gain matches RTG TARGET.
b. Close the sound chamber lid when finished.
c. Look at the display again. The MEASURED gain should be within 1 dB of
the TARGET gain for ANSI 96, or 1.5 dB for ANSI 03.
