Official title
Spatially Transparent Binaural Beamforming for Noise Reduction for Cochlear Implant Processors
Overview
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
Interventions
- 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
Primary outcome measures
- Percent correct scores on speech perception in noise. [Time frame: Enrollment to 9 months]
- Root mean square error for sound source localization [Time frame: Enrollment to 9 months]
Eligibility criteria
