AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children and adults who use a cochlear implant together with their own remaining hearing (EAS). It also needs children and adults with normal hearing to compare with.
- Age
- Children with EAS: 5-17 years. Adults with EAS: 18+ years. Minimum age 5 Years.
- Sex
- All sexes can join.
- Disease stage
- EAS group: at least one cochlear implant and mild to profound hearing loss in both ears of the inner-ear or nerve type (sensorineural). Unaided hearing thresholds ≤ 80 dB HL at 125 and 250 Hz in both ears. Normal hearing group: thresholds 20 dB HL or better from 250-8000 Hz.
- Earlier treatment
- EAS group: must have at least one cochlear implant (CI). They must be willing to use EAS technology in the implanted ear(s), checked by device data logging.
Main reasons for not taking part
- Deafness in only one ear (single-sided deafness, SSD)
- Other diagnoses such as autism, auditory neuropathy, a neurological disorder or general cognitive impairment
- Nonverbal thinking skills outside the typical range
- Spoken English is not the main way of communicating

Who can take part
- Pediatric EAS: aged 5-17; Adult EAS: aged 18+ years
- At least one CI and bilateral mild to profound sensorineural hearing loss with unaided audiometric thresholds ≤ 80 dB HL at 125 and 250 Hz, in both ears; Willingness to use EAS technology in the implanted ear(s) to be verified via data logging; Nonverbal cognitive abilities within the typical range; No co-morbid diagnoses such as autism, auditory neuropathy, neurological disorder, or general cognitive impairment; Use of spoken English as main mode of communication
- For children and adults with normal hearing, they will demonstrate audiometric thresholds 20 dB HL or better from 250-8000 Hz

About the trial
What the trial wants to find out
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.
The 4 groups in the trial
- Children with normal hearing
Treatment: binaural processing over time and binaural processing over time for children and adults with normal hearing
- Adults with normal hearing
Treatment: binaural processing over time for children and adults with normal hearing
- Children with bilateral steeply sloping sensorineural hearing loss
Treatment: binaural processing over time
- Adults with bilateral steeply sloping sensorineural hearing loss
Treatment: binaural processing over time
