A4-ESR: Optimizing cochlear implant coding strategies in the context of the electrode-neural information bottleneck

Because of the information bottle neck, it is impossible to match the resulting neural activity close to a normal ear. Therefore the approach of commercial coding strategies is to only transmit part of the auditory information. Channel selection is critical for performance. However, selecting the highest energy bands as – as is done in today’s CIs - leads in noisy situation to loss of intelligibility (Hu and Loizou, 2008; Dawson et al., 2011). In this project we aim to better understand the impact of this information selection specifically for the default strategy used in Cochlear products (ACE) and to develop improved strategies.
