Study Details

Brief summary:

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 and Outcome Measures

Arms

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.

Interventions

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 measure

  • 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 ]
