New article about ABF published in Nature

Interesting article published in a Nature journal this month.

Aljazeeri, I.A., Hagr, A. Application of anatomy-based spacing of electrode contacts for achieving a uniform semitonal resolution: A novel concept in cochlear implant electrode design. Sci Rep 14, 2645 (2024). https://doi.org/10.1038/s41598-024-53070-8

As I understand it, they examined Med-El's Anatomy Based Fitting, ABF, with 200 ears.  Results suggest that outcomes might be further improved by changing the electrodes to have varying spacing of the contacts rather than the current fixed (constant) spacing between each electrode done by Med-El and the other companies.

Perhaps there are issues such as electrical interference among the signals of adjacent electrodes as they get close.  This is another area where the wild "optical excitation" for an optical cochlear implant will benefit.  It will be interesting to see where the technology goes in the future. Again, happy Cochlear Implant Day.
