More and more cochlear implant (CI) patients are choosing to wear a hearing aid in their contralateral ear. Yet many hearing aids currently being fitted along with CIs are poorly balanced1. To help patients benefit more fully from a bimodal fitting, we have added a bimodal fitting guide to our Genie fitting software for Oticon Dynamo and Sensei Super Power.

Use Dynamo or Sensei Super Power with any cochlear implant

If you haven’t yet been asked to manage a unilaterally implanted patient, it is only a matter of time before you will be. Via a short and simple flowchart, the bimodal fitting guide in Genie takes you through the steps of programing a Dynamo or Sensei SP hearing aid to work with any brand of cochlear implant

Developed at Boys Town National Research Hospital

Developed by experts at Boys Town National Research Hospital, the bimodal guide in Genie provides an evidence based, yet practical, method for fitting a hearing aid on a bimodal patient.

In just a few simple steps the flowchart guides you to balance loudness and to shape the frequency response. The purpose is to provide your patient with the best possible acoustic settings to balance with CI mapping when fitting an implanted patient with a Dynamo or Sensei SP hearing aid.

The bimodal fitting protocol takes into account the following fitting approaches:

  • Wideband fitting 
  • Restricted bandwidth fitting 
  • Use of frequency lowering 
  • Loudness balancing

How will it benefit your patients?

  • Bimodal fittings deliver proven benefits for patients, including:
  • Improved experience of sound and music (acoustic and electric) 1a, 1b 
  • Higher quality of life in social activities
  • Improved ability to hear speech in noise 3 
  • Enhanced sound localisation skills 4 
  • Stimulation early in life with both acoustic and electric sound can potentially benefit children in their musical, speech and language development and potentially affect the child’s future academic success.5
