An interventional study of Modifying audio input for cochlear implant processor in Cochlear Implant Users, sponsored by University of Illinois at Urbana-Champaign. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-02.
Sponsored by University of Illinois at Urbana-Champaign · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to determine if a new algorithm can improve speech perception for cochlear implant users. The main questions it aims to answer [is/are]:
Participants will
University of Illinois at Urbana-Champaign is the lead sponsor of 191 studies on the registry; 29 are open to participants now.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Participants will listen to stimuli processed by different beamformer algorithms and repeat speech presented in noise and identify the location that sound originated from.
Device: Modifying audio input for cochlear implant processor
Sound will be preprocessed with different beamformer algorithms and presented either through the auxiliary input port or via a streaming device to the participants' cochlear implant processor
Percent correct scores on speech perception in noise.
The speech perception in noise test consists of lists of sentences in the presence of multi-talker babble or diffuse noise. The target location will vary across conditions. Participants will need to repeat back as much of the target sentence as they can.
Time frame: Enrollment to 9 months
Root mean square error for sound source localization
The localization test will involve a target speaker in the presence of multi-speaker babble or diffuse noise. The virtual location of the sound sources will be manipulated and participants will need to indicate the location of the target speaker.
Time frame: Enrollment to 9 months
Plan to share: Yes — The de-identified behavioral IPD from all experiments will be shared with the exception of pilot data.
Time frame: The data that will be shared will be made available no later than the time of an associated publication or one year after the end of the performance period. Per the policies of the Illinois Data Bank, data will be available for at least five years after it is first shared.
Access criteria: Data that will be shared will be stored in the Illinois Data Bank, a data repository managed by the University of Illinois. The data will be publicly available via the Illinois Data Bank.
