What this Trial Is About
Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. Improvements in surgery and electrodes have results in an increased number of adults and children who have residual hearing and can benefit from electric and acoustic hearing in the same ear. This is called Electric Acoustic Stimulation (EAS). Many studies have shown that adult EAS users show significant benefits for speech understanding in noise and spatial hearing tasks as compared to a CI paired only with a contralateral HA. Even though this type of hearing is becoming more common, there is limited research on how it can be beneficial to children with CIs. The benefits of this study are a greater understanding of the participant's speech understanding, binaural processing, and spatial hearing. The results will help audiologists and researcher better understand how cochlear implants work, specifically when using electric and acoustic hearing in the same ear.

Eligibility Criteria
You may qualify if you...
- Children aged 5 to 17 years with normal hearing or at least one cochlear implant and binaural low-frequency acoustic hearing
- Adults aged 18 years or older with normal hearing or at least one cochlear implant and binaural low-frequency acoustic hearing
- Experimental participants must have at least one cochlear implant and bilateral mild to severe sensorineural hearing loss
- For cochlear implant participants, the non-implanted ear must have at least mild sensorineural hearing loss, not single-sided deafness
- Unaided hearing thresholds must be 80 dB HL or better at 125 and 250 Hz in both ears
- Participants must have nonverbal cognitive abilities within the typical range
- Adults must pass cognitive screening via Montreal Cognitive Assessment (MoCA or HI-MoCA)
- No diagnosis of autism, auditory neuropathy, neurological disorder, or general cognitive impairment
- Willingness to use Electric and Acoustic Stimulation technology in the implanted ear(s) verified by device data logging
You will not qualify if you...
- Nonverbal intelligence standard score below 85 for any participant
- MoCA or HI-MoCA score below 26 for adult participants
