Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include children aged 5 to 17 and adults 18 years and older with cochlear implants and residual low-frequency acoustic hearing.
✕Probably not a fit
Patients with single-sided deafness or those with confounding diagnoses such as autism may not benefit from this study.

What this trial studies
This study investigates the benefits of combined Electric and Acoustic Stimulation (EAS) in children and adults with cochlear implants. It aims to understand how this approach can improve speech understanding and spatial hearing by utilizing both electric and acoustic signals in the same ear. Participants will include both children and adults with varying degrees of hearing loss, and the study will assess their auditory processing abilities through behavioral and objective measures. The findings are expected to enhance the understanding of cochlear implant functionality and inform audiological management for EAS candidates.
Why it matters
Potential benefit: If successful, this study could significantly improve hearing outcomes and quality of life for children and adults with cochlear implants.
How similar studies have gone: Previous studies have shown significant benefits of EAS in adults, but research on pediatric outcomes is limited, making this approach relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Children aged 5 to 17 years of age with either normal hearing (n=40) or at least 1 cochlear implant (CI) and binaural low-frequency acoustic hearing (n=40); adults aged 18+ years with either normal hearing (n=40) or at least 1 CI and binaural low-frequency acoustic hearing (n=40). 2. Experimental participants must have at least one CI and bilateral mild to severe sensorineural hearing loss For CI participants, audiometric thresholds in the non-CI ear must be consistent with at least a mild sensorineural hearing loss; that is, the investigators will not be enrolling participants with single-sided deafness (SSD) For CI participants, unaided audiometric thresholds must be less than or equal to 80 dB HL for 125 and 250 Hz, in both ears. 3. Nonverbal cognitive abilities within the typical range for all participants; adult participants must also pass cognitive screening via Montreal Cognitive Assessment (MoCA or HI-MoCA). 4. No confounding diagnosis such as autism, auditory neuropathy, neurological disorder, or general cognitive impairment. 5. Willingness to use EAS technology in the implanted ear(s) to be verified via data logging from cochlear implant and hearing aid software. Exclusion Criteria: 1. Nonverbal intelligence standard score \< 85 (for any participant). 2. MoCA or HI-MoCA score \< 26 for adult participants.
