5.4 Impedance
Impedance is a measurement of how sound energy flows through the middle
ear. Although FONIX equipment does not measure impedance, if you have per
-
formed the measurements with an impedance audiometer, you can store the
data here. When importing data from NOAH 3 (See Chapter 8), any impedance
data saved to the patient’s record will be transferred to this window.

5.5 Hearing Aid Analyzer Functions
From the Audiometric Test window, you can generate a target (NAL-R, POGO,
BERGER, 1/3 Gain, 1/2 Gain, or 2/3 Gain), send it to a connected FONIX ana-
lyzer, and start a hearing aid test.
5.5.1 Generating a target
1. Click on the Target button. A new window will open (Figure 5.5.1).
2. Select whether you would like to use the left or the right audiometric
curve when generating a target.
3. Select the desired fit rule.
4. Click Create Target Curve. A message will open verifying the successful
creation of the target curve.
