Interventions

  • binaural processing over time — BEHAVIORAL
    This study will not provide an intervention, but will study the effects of hearing technology on binaural processing for adults and children with bilateral steeply sloping sensorineural hearing loss
  • binaural processing over time for children and adults with normal hearing — BEHAVIORAL
    Adults and children with normal hearing will be studied over time to characterize binaural processing and associated effects on speech perception in complex listening scenarios and spatial hearing abilities.

Study Details

There is a rapidly growing population of adult and pediatric cochlear implant (CI) recipients with acoustic hearing preservation in the implanted ear(s) allowing for combined Electric and binaural Acoustic Stimulation (EAS). Despite the rapid technological and surgical advancements that have led to this increased prevalence, there is limited research on EAS outcomes-particularly for pediatric EAS listeners-including the expected trajectory of benefit following EAS fitting and underlying mechanisms driving benefit in EAS users of all ages. Thus, the purpose of this project is to provide a comprehensive description of behavioral and electrophysiologic measures of binaural hearing in adults and children both with normal hearing and EAS users.
