In this episode, Marcus Schmidt is joined by Prof. Sumit Agrawal and Dr. Peter Nopp to explore how cochlear anatomy shapes cochlear implant design and performance. They discuss breakthrough synchrotron imaging, the variability in cochlear size and structure, and why deep insertion and full cochlear coverage matter for natural, rich sound.
