Assessment of a Method to Improve Cochlear Implant Users' Speech Perception in Noisy Environments While Maintaining Their Ability to Determine Where a Sound Originates From

January 6, 2026 updated by: University of Illinois at Urbana-Champaign

Spatially Transparent Binaural Beamforming for Noise Reduction for Cochlear Implant Processors

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]:

  • Does the algorithm improve speech perception in noisy environments?
  • Does the algorithm allow listeners to determine where a sound is coming from?

Participants will

  • Listen to and repeat sentences presented in the presence of noise
  • Indicate the location that sounds originated from

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Speech perception and localization with different beamformers
Participants will listen to stimuli processed by different beamformer algorithms and repeat speech presented in noise and identify the location that sound originated from.
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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent correct scores on speech perception in noise.
Time Frame: Enrollment to 9 months
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.
Enrollment to 9 months
Root mean square error for sound source localization
Time Frame: Enrollment to 9 months
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.
Enrollment to 9 months

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The de-identified behavioral IPD from all experiments will be shared with the exception of pilot data.

IPD Sharing 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.
