Cochlear implant (CI) devices do not reliably transform all acoustic features, and thus may affect categorization and recognition of everyday sounds. We compared auditory categorization and sound recognition of human-generated vs environment in prelingually-deaf children with CIs (N=10) to 29 age-matched normal hearing peers (NH) in two online game-based tasks using Zoom. The CI and NH group performed similarly when listening to human-generated sounds (e.g. vocalization, laughter), but children with CIs had more difficulty categorizing and identifying some of the environmental sounds (e.g. household sounds, instruments). These results have important implications for understanding how children with CIs process environmental sounds.
