  • Analysis of current speech-processing strategies and their impact on auditory perception.
  • Consideration of novel materials and designs for next-generation electrode arrays.

    • Main Results:

    • Existing cochlear implant strategies show promise in improving frequency discrimination and musical perception.
    • Better reproduction of neural temporospatial patterns is linked to phase differences in neuron firing.
    • Next-generation electrode arrays offer potential for more exact sound reproduction.

    Conclusions:

    • Cochlear implants offer significant benefits for hearing in noise and music perception.
    • Advancements in electrode array design, potentially using neurotrophins and conducting polymers, are promising.
    • Further investigation into the siting, design, and safety of new technologies is essential before clinical implementation.
