Abstract
Binaural hearing is important for listening in and navigating everyday acoustic environments. Unilateral deafness during development drives extensive reorganization in bilateral auditory pathways, limiting spatial hearing and putting children at risk for social and educational challenges. In an effort to reduce these listening challenges and support bilateral development, implantation criteria are expanding to provide children who have asymmetric hearing loss a cochlear implant for the deaf ear and a hearing aid to the other ear when needed, known as bimodal hearing. Our work has assessed hearing development in bimodal users through evoked potentials and behavioural measures of spatial hearing and speech perception. This talk will discuss how bimodal hearing can promote symmetric bilateral development but faces limitations for preventing or reversing asymmetry-driven reorganization when implantation is delayed or residual hearing is insufficient. Challenges still faced by children who hear bimodally will also be discussed.
