Summary

This research is being done to determine whether a test that measures a "Visual Evoked Potential" can be used in a new way for individuals that have hearing loss. This test measures the participant's brain's response (so called "brain waves") to specific visual images. This study will help the investigators determine whether this test could be used to improve treatments for patients with hearing loss.

The "Visual Evoked Potential" measurement test is already used in the investigator's Neurology clinic at Dartmouth Hitchcock Medical Center for various conditions to measure "early" brain responses that occur in the first 1-2 seconds after a new cue. Our research aims to explore your brain's response just after that early 1-2 second period by looking at a specific response called the "P300". The P300 wave is a brain response to new or different images or sounds. A visual evoked P300 has not been studied in individuals with hearing loss.

The investigators will compare the results of this test to standard auditory tests, tests of cognitive function, and cochlear implant patient outcomes to explore how these factors can predict successful use of a hearing aid or cochlear implant.
