Target Preferences

Target Preferences identifies default target levels, volume control, fitting formulas, best fit, etc.

1. Click Preferences from the Menu Bar.

2. Click Target.

3. Enter or edit target settings.

   Field Name	Description	Details
   Soft	Selects the default soft target level.	The levels available are None, 40, 45, 50, and 55. The default value is 50 dB SPL. If None is selected, the soft target and response curves will not display.
   Moderate	Selects the default moderate target level.	The levels available are None, 60, 65, 70, and 75. The default value is 65 dB SPL. If None is selected, the moderate target and response curves will not display.
   Loud	Selects the default loud target level.	The levels available are None, 80, 85, 90, and 95. The default value is 80 dB SPL. If None is selected, the loud target and response curves will not display.
   Volume Control
   Modify Reserve Gain Without Prompting	Denotes whether or not a prompt should display anytime the reserve gain is modified.	If selected, which is checked by default, Inspire Best Fit will modify the reserve gain without prompting when necessary. If not selected, a prompt will appear if the reserve gain is modified to best match the fitting formula target. Click OK to apply changes to the reserve gain or click Cancel to ignore the changes made and revert back to the original settings.
   Reserve Gain (Button)	Customizes the default reserve gain values per style and fitting formula.	Reserve gain can be set from 0-20 dB in 2 dB steps. The default is 10 dB for all custom styles with or without volume controls, 0 dB for all On the Ear (OTE) and Receiver in the Canal (RIC) devices (except RIC T2, which is 10 dB), and 14 dB for all Behind the Ear (BTE) devices (except BTE 13 no VC (WFA fitting formula only) and BTE 312 no VC, which are 0 dB).
   Default Digital Volume Control Range	Selects the default range for the digital volume control (for select products) on the Fine Tuning screen.	The options available are 8, 12, 20, and 40 dB. By default, the digital volume control range is set at 20 dB.
   Experience Level
   Apply default at Best Fit	Denotes whether or not to apply an automatic gain offset within the fitting.	By default, this gain offset is automatically applied.
   Experience Level	Selects the default gain offset to apply within the fitting.	The options available are Inexperienced, Familiar, Experienced, and Transition (T). The default setting is Experienced.
   Fitting Formulas
   Non-Linear	Selects the non-linear fitting formulas that will be available in the drop down list from any Fitting screen.	The non-linear fitting formulas available are NAL-NL1*, e-STAT, NAL-NL2, NAL-NL1, and DSL v5. By default, all fitting formulas are selected.
   Preferences (Button)	Identifies the default settings exclusively for the DSL v5 fitting formula.	See Preferences for more information.
   Linear	Selects the linear fitting formulas that will be available in the drop down list from any Fitting screen.	The linear fitting formulas available are NAL-R, Berger, and WFA. By default, only NAL-R is selected.
   Select Default Formula	Selects the default fitting formula for new hearing aids or when simulating hearing aids.	The fitting formulas available are based on the non-linear and linear fitting formulas selected with the exception of NAL-NL1*. This formula cannot be selected as the default formula regardless if it's selected or not. The default fitting formula is e-STAT.
   Miscellaneous
   Multicurve Level	Selects the input level at which to view settings for all active memories of a multi-memory device when the Multicurve display option is selected from the Display menu.	The levels available are 40-95 dB SPL in 5 dB steps. The default multicurve level is 65 dB SPL.
   Target Input Stimulus	Selects the desired input stimulus for the fitting formula target calculation.	The options available are Speech and Sinusoidal. The default is Speech.
   Binaural Correction	Selects the desired target correction value used in binaural fittings to compensate for the binaural summation effect obtained when fitting both ears. The fitting formula target for each ear will be reduced by the dB value selected.	The options available are 0, 3, and 5 dB. The default value is 3 dB.
   Air-bone Gap Correction	Selects the desired target correction value to be used when the audiogram indicates an air-bone gap, or a difference between the thresholds obtained by air conduction and bone conduction. The fitting formula target values will be increased by the percentage of the air-bone gap selected.	The options available are 0, 25, 50, 75, and 100%. The default air-bone gap correction is 25%.
   Best Fit Options
   Perform on fitting formula change	Denotes whether or not to perform a Best Fit each time a different fitting formula is selected.	The default is to perform a Best Fit whenever the fitting formula is changed.
   Include Maximum Output	Denotes whether or not to include maximum output adjustments each time a Best Fit is calculated.	The default is to include maximum output whenever a Best Fit is calculated.

4. Click Reserve Gain.

5. Click in the reserve gain field to change.

6. Click on the desired value from the drop down list.

7. Click OK.

   Tip:  Click Cancel to discard the changes.

8. Click Preferences.

9. Enter or edit DSL v5 options.

   Field Name	Description	Details
   Audiometry	Selects the default transducer type on the Fitting Formula Options screen.	The transducers available are Insert Headphone, Insert Earmold, TDH Headphone, Loudspeaker 0°, Loudspeaker 45°, Loudspeaker 90°, and Real Ear SPL. The default Audiometry type is Insert Headphone.
   ABR	Denotes whether or not reinterpretation of air-conduction thresholds as ABR thresholds is allowed.	This field is only available if the selected transducer is one of the ABR-compatible choices of Insert Headphone or Insert Earmold.
   nHL/eHL	Indicates if the ABR units are nHL or eHL.	nHL is the typical ABR reference with units of dB nHL (normalized hearing level), to which Inspire will apply a frequency-specific conversion to obtain the dB HL equivalent and eHL is the already-converted ABR threshold with units of dB eHL (estimated hearing level), which already corresponds to the dB HL equivalent.
   Apply Changes Binaurally	Denotes whether or not the ‘nHL to eHL conversion’ values should be changed for both sides if altered.	If selected, any changes made to one side will automatically populate to the other side.
   nHL to eHL Conversion	Identifies the default ‘nHL to eHL conversion’ values used within the Fitting Formula Options screen.	Values must be between -30 and 60. These fields are only available if ABR and nHL are selected.
