connect the aids

    One Fitting Cable
         • All Sonic Innovations products
           programmed via same fitting
           cable
         • Simply plug the fitting cable into
           the programming port




Hands On: Practical Application of Sonic Science   12
connect the aids

    Fitting Cable for
    Custom Products:
         • Attach flex strip to fitting cable
         • Open battery door
         • Place flex strip in space between
             battery door hinge and hearing
             aid shell
                       gold contacts on flex strip face
                          away from the battery door
         • Close battery door to secure the
             flex strip in place




Hands On: Practical Application of Sonic Science          13
launch                                             fit

    •NOAH
      • Launch the EXPRESSfit
        Fitting Module

    •                             fit Standalone
         • Create new patient record
           or select existing record
         • Launch Fitting Module

    •Follow on-screen prompts




Hands On: Practical Application of Sonic Science         14
enter or review the audiogram

    • Audiogram
             • Enter the audiogram
                 (EXPRESSfit Standalone) or...
             •   Review the audiometric data
                 entered (NOAH)
             •   Make modifications
             •   Enter Speech Scores
             •   Enter Measured Real Ear
                 data.


          Quick Fact:
          The Best Fit Fast algorithm uses the
          audiometric data (air conduction and
          bone conduction values) as the
          foundation for predicting the patient‟s
          residual dynamic range.
Hands On: Practical Application of Sonic Science    15
verify the dynamic range

    • Dynamic Range...
             • Verify audiogram prediction
               in situ
             • Increase or decrease
               dynamic range values
             • Optional step



          Quick Fact:
          Hearing aid fittings create “resonances”
          and “anti-resonances” in the ear canal,
          which can degrade sound quality. When
          performing the Verify Dynamic Range
          procedure, the patient hears a strong
          resonance as an unusually loud tone; a
          strong anti-resonance is heard as an
          unusually soft tone.
Hands On: Practical Application of Sonic Science     16
fine-tune predicted fitting values

    • Fit Hearing Aid
             • Main „Control Center‟
                Review fitting values
                Modify listening program
                Solve patient complaints
          Quick Fact: common
           • Address most
          Quick Fact: If the predicted fitting values
              patient issues:
          are too soft, use the Fitting Levels
                Feedback
          (located on the toolbar at the top of the
                Sound quality
          screen) to quickly increase the amount of
                Own voice
          amplification. You can verify that the
                Asymmetric hearing loss
          Fitting Level is set correctly with the
          „crinkle test‟. Have your patient crinkle a
          piece of paper, then ask if the paper
          sounds the way it feels. Keep increasing
          the Fitting Level until the patient says the
          paper sounds more like plastic or metal,
          then decrease one level.

   Aid Info to account for a Thin
   Tube and Open Dome.
  • Since Jamal‟s new job is as a
   traveling salesman, he
   spends quite a bit of time in
   the car. Give him a program
   suited for this.
  • Configure his (your) Bluetooth
   phone to communicate with
   his aids via sonicBLU.
