Unitron TrueFit software instruction guide v2.2

Note: For environments that offer mixed inputs (e.g., Telecoil + Microphone, Audio

Streaming + Mic, Direct Audio Input + Mic), the microphone level can be adjusted using

the mic attenuation slider in 3 dB steps from 0 to -30 dB with the exception of easy-DAI.

Note: When binaural phone is activated, the input selection task box offers the ability

to configure phone ear inputs (Telecoil + Microphone with 0 to -30 dB mic attenuation;

or Omni) and non-phone ear inputs (Audio Streaming + Mic with optional 6 dB mic

attenuation available with some products).

Tinnitus Masker

Note: This option is available when the product supports this feature.

1. Click the Tinnitus Masker task item at the bottom of the screen.

Note: The graph view will automatically change to 'output' upon selection of the

tinnitus masker task box to allow you to view the tinnitus masker output level relative

to the hearing aid output settings.

2. Click the Enable Tinnitus Masker check box to activate the masker noise.

Note: The tinnitus masker noise is disabled by default. When it is enabled, the quick fit

level should be at a soft but audible level.

Note: The calculated masker noise level with the current settings will be displayed in

dB(A) in the task box.

3. Click the checkbox beside Use client control to adjust noise level to allow patient

to adjust the noise level using any volume or SmartFocus control on the hearing

instruments or accessories. Selecting this option will prevent the client from

adjusting the gain or the SmartFocus setting for this program.

Note: This setting is binaural and cannot differ across hearing instruments in the same

fitting, even if the tinnitus masker is disabled or not available in one hearing instrument.

4. Select the frequency resolution you require for your modification using the provided tabs.

Note:

The frequency resolution depends on the technology level of the product you are fitting.

5. Select the frequency region(s) to be modified in the table.

• To select an individual frequency region, select the desired value in the table.

•

An entire frequency range of fitting values can be selected by choosing the 'Noise' label.

• To select multiple frequency regions for adjustment, you can also click and drag

across the table. The slider bar along the bottom of the table allows you to view

frequency regions that are outside the visible table area.

• To view all frequency regions for a particular ear, and/or increase the size of the

selectable boxes in the table, click on the View right ear only or View left ear

only text as appropriate. To change the table view back to a binaural view, click

on the text View both ears.

• Once you have selected your desired frequency region for adjustment, click the dB

drop-down menu to alter the step size of any change. Choose from 1, 2 or 3 dB.

• Click the + or - buttons to apply the desired change.

Note: When a fitting handle has reached its maximum setting, the + button will grey out

(disable). Conversely, if a fitting handle is at its minimum setting, the - button will grey

out (disable).

Note: The alerts tab will highlight once the generated masker noise setting reaches a

value of 80 dB(A) or greater to indicate that care should be taken when exposing the

client to continued noise at this level to avoid an adverse impact on hearing. A

recommended daily usage time based on NIOSH standards

(http://www.cdc.gov/niosh/docs/98-126/) will also be indicated considering the current

masker noise level and updated as the noise level is adjusted. The noise level settings
