Who can participate?

  • Infants, children, and adults who use a cochlear implant in at least one ear
  • Infants, children, and adults who have normal hearing

What happens in the study?

For infants:

  • Your child will sit on your lap or age-appropriate chair in a quiet room with one of our study helpers
  • The helper will engage your child in age-appropriate play
  • Your child’s responses to different sounds will be recorded by researchers observing through a window from outside the booth

For older children and adults, they will raise a hand, press a keyboard button, or mouse click when they hear a different sound.

For cochlear implant users:

  • You or your child will wear their sound processor and listen to sounds presented at a comfortable loudness from a speaker in the room
  • In some studies, a new signal processing strategy will be tested, which changes how sound information is coded by the CI

What are the logistics?

  • Infants will be tested up to 10 visits over a 2-5 month period
  • School-age children and adults will be tested over 1-3 visits
  • Each visit will last between 1 to 3 hours including breaks
  • Scheduling is flexible!
    • We will schedule visits whenever is convenient for you
    • Testing is possible on the weekends
    • A babysitter is provided at no charge for siblings (currently not available due to pandemic conditions)
    • We can try to schedule your study visits the same day that your child has appointments at Seattle Children’s Hospital
  • Reimbursement includes $15.00 per hour as well as parking
  • There are no costs to you and no insurance billing
  • Reimbursement for travel expenses and local lodging may be available for some participants.  Please inquire with study personnel.
