Study Overview
Brief Summary
This is a basic investigational research study conducted with hearing impaired adults and children who use cochlear implant or auditory brainstem implant (ABI) devices. The study will evaluate different aspects of hearing and auditory processing in the users of implantable auditory devices.

Eligibility Criteria
- Ages
- 2 Years to 90 Years (Child, Adult, Older Adult)
- Sex
- All
- Accepts Healthy Volunteers
- No
Inclusion Criteria
- •Hearing impaired adult and or child (above 2 years old) who uses ABIs or cochlear implants.
- •No diagnosis of any other communicative or cognitive disorder other than hearing impairment. The individual must be able to visit the lab in order to participate in behavioral and electrophysiological experiments.
- •Patients' implant device must have useable electrodes that do not result in uncomfortable or unpleasant non-auditory sensation.
Exclusion Criteria
- •Diagnosed cognitive or communicative disorders (other than hearing impairment)
- •Severe neurological disorders
- •No useable electrodes in their implants
Arms & Interventions
Hearing-Impaired Individuals who use Cochlear Implants or Auditory Brainstem Implant (ABI) Devices
Two types of measurements will be obtained:
- Perceptual: one or more sounds are presented and a behavioral response is collected (e.g., judgements of loudness, pitch or other differences between the sounds, or identifying the word or sentence that was said).
- Physiological: noninvasive electrophysiological recordings of nervous system activity.
Intervention: Electrode-Neural Interface (Device)
Outcomes
Primary Outcomes
Percent of Correctly-Identified Stimuli Characteristics when Two or More Stimuli are Presented
Time Frame: Day 1 (Visit 1 - Average visit length is about 3 hours)
Two or more stimuli will be presented to participants, who will indicate which one is louder, which is higher pitched, or which one is different. The outcome is the percent of stimuli characteristics that are correctly identified.
Percent of Correctly-Identified Speech Materials
Time Frame: Day 1 (Visit 1 - Average visit length is about 3 hours)
Participants will listen to speech sounds and indicate what sentence or word they heard. The outcome is the percent of speech sounds that are correctly identified.
Secondary Outcomes
No secondary outcomes reported
