Summary

This trial studies the benefits of cochlear implants for hearing impaired adults and children, restoring their ability to hear with electric & acoustic hearing in the same ear.

Who is the study for?
This trial is for children (5-17 years) and adults (18+ years) with hearing loss who can benefit from a cochlear implant combined with a hearing aid in the same ear. Participants must have some low-frequency hearing left, be willing to use EAS technology, and have typical cognitive abilities. Adults should not have single-sided deafness or any confounding diagnoses like autism or general cognitive impairment.
What is being tested?
The study tests Electric Acoustic Stimulation (EAS), which combines a cochlear implant with a hearing aid in one ear, aiming to improve speech understanding and spatial hearing. It will compare the benefits of EAS in both children and adults against those using only standard cochlear implants.
What are the potential side effects?
While specific side effects are not listed for this trial, generally speaking, risks may include surgical complications from the cochlear implant procedure, skin irritation from wearing devices, potential over-amplification of sound causing discomfort or additional hearing damage.
