6.3.2 Deleting Audiometric Information
If you make a mistake, it’s often useful to be able to delete all or part of the
inputted audiometric data. To do this:
1. Press [F4] and use [∨, ∧] to select the data you would like to delete. You can
delete the client’s HTL, UCL, Bone, and RECD. Selecting “This Ear” will
delete all data in the selected ear. Selecting “New Client” will delete all data
in both ears.
2. Press [>] to perform the action.
6.3.3 Creating a Target
Once you input an audiogram (Section 6.3.1), a target will automatically be cre-
ated when you enter a real-ear measurement screen.
To change a fitting rule:
1. Press [MENU] from the real-ear measurement screen or the Audiogram Entry
screen.
2. Select Fitting Rule under Targets with [∨, ∧].
3. Use [<, >] to select the desired fitting rule.
4. Use [∨, ∧] to select Client Age, and use [<, >] to input the desired selection.
5. If you have selected NAL-NL1, the following menu settings are also avail-
able:
• Compression: The compression kneepoint of the hearing aid. If the hear-
ing aid has multiple compression kneepoints, use the first one.
• No. of Channels: The number of channels of the hearing aid.
• Aid Limit: Type of output limited employed by the aid. Choose from
Multichannel or Wideband.
• Fit Type: Type of hearing aid fitting used by the patient. Choose Unilateral
or Bilateral.
• Sound Field: Position of the sound field speaker during real-ear measure-
ments. If the patient’s threshold values were measured with a sound field
speaker, the same angle used for the audiometric measurements should be
used for the real-ear measurements.
• Ref. Position: Type of leveling used for the real-ear measurement. Head
surface includes the patient inside the sound field (recommended for best
accuracy). Undisturbed Field indicates leveling was done by holding the
reference microphone in front of the sound field speaker.
6. Press [EXIT] to close the menu. If you are in a real-ear measurement
screen, you should see the new selected fitting rule noted under the Curve
Characteristics box.
