Investigating Auditory Processing in the Users of Auditory Brainstem and Cochlear Implants

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

Electrode-Neural Interface

Device

Measurements taken from the electrode-neural interface will be used to guide elimination of poorly functioning ABI electrodes and improve speech perception outcomes.

Primary outcomes

  1. 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.

  2. 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.
