| contents | This study evaluated whether AutoSense Sky OS, an automatic classifier used in pediatric Advanced Bionics cochlear implants (CIs), improves speech intelligibility from the front without significantly impairing spatial awareness (i.e., sound detection and identification from all directions), with the main focus on the classroom situation. A double-blind crossover study was conducted with 12 pediatric CI users aged 7-16 years. Participants tested two settings: one with AutoSense Sky OS activated and the other with an omnidirectional microphone mode. Speech intelligibility from the front and spatial awareness were assessed in a virtual classroom environment using a Virtual Reality headset and a 12-loudspeaker array. Participants also rated the performance of each setting during a take-home period. A technical evaluation revealed that AutoSense Sky OS activated its directional microphone mode in the virtual classroom, and during the listening test this significantly improved speech intelligibility from the front while significantly reducing spatial awareness. While not all participants reported noticeable differences between settings in daily life, 8 out of 12 children preferred "AutoSense on", perceiving improved speech intelligibility in noisy environments. Conversely, some participants preferred "AutoSense off" due to poorer localization and speech intelligibility from behind with "AutoSense on". In conclusion, the automatic classifier provided improved speech understanding in noisy conditions such as a classroom, at the cost of a slightly reduced spatial awareness. The preference for AutoSense Sky OS among CI children and their parents appears to be a matter of individual trade-offs between improved speech intelligibility in noisy conditions and reduced spatial awareness. |
