|---|---|---|---|
| Speech perception and localization with different beamformers | Experimental | Participants will listen to stimuli processed by different beamformer algorithms and repeat speech presented in noise and identify the location that sound originated from. |

| Modifying audio input for cochlear implant processor | Device | 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 |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | 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. | Enrollment to 9 months |
