Study of Binaural Hearing and Speech Recognition in Children and Adults Using Electric and Acoustic Stimulation with Cochlear Implants

What this Trial Is About

Researchers are studying binaural hearing abilities in both adults and children who use cochlear implants with preserved natural hearing, allowing combined Electric and Acoustic Stimulation EAS. This research aims to understand the patterns of benefit from EAS, especially in children, and to explore how hearing develops with this technology compared to individuals with normal hearing. The study seeks to fill gaps in knowledge about EAS outcomes and improve clinical care for cochlear implant users. Participants include adults and children with sensorineural hearing loss using EAS technology, as well as age-matched individuals with normal hearing. The study tracks behavioral and brain responses to sounds to assess sensitivity to timing and level differences between ears. These measures are collected over time to evaluate speech recognition in noise and spatial hearing abilities. The study does not provide treatment but observes hearing using specialized tests. During the study, participants will undergo evaluations of hearing abilities and binaural processing at multiple points over two years. Researchers will collect data on speech understanding and spatial hearing performance, using objective and behavioral measures. The results will help understand how binaural hearing develops with EAS and guide improvements in cochlear implant fittings and clinical recommendations. Participation lasts for up to two years with ongoing assessments to monitor changes in hearing function.
