Understanding How Infants Hear and Process Speech Sounds (SPOT Study)
In this study we want to learn how infants hear speech sounds and how that affects their language development.
Why this Research Matters
Right now, it’s hard to know how babies tell different speech sounds apart, because they can’t talk yet to let us know what they hear. This matters because children who can’t tell speech sounds apart are at risk for language delays. In this study, we are trying new ways to test how babies hear and notice speech sounds. What we learn may help scientists and doctors find better ways to support babies who use hearing devices.
What to Expect
We will use three types of hearing tests in this study. (1) Tympanometry, which is a small, soft probe that checks your baby’s eardrum movement. (2) Otoacoustic Emissions, which checks for sounds that come back out of the ear after a tone is played. (3) Oscillatory EEG, where sticky sensors (electrodes) are placed on your baby’s head while sounds play through speakers. This shows how their brain responds to sound. Parents will also fill out short surveys about their child’s hearing and health history.
Study Duration
If your child joins, you will be asked to come to between one and five study visits at the University of Colorado Anschutz or at a Children’s Hospital Colorado location. We also have the ability to see you in your home, if preferred. Each visit will last two to three hours. Visits will take place when your child is between 1 and 12 months old.
Who can Participate
Your child may be able to join this study if they:
- Are between 1 and 12 months old
- Have been diagnosed with permanent hearing loss in both hears
- Wear hearing aids
- Live in a home where English or Spanish is the main language spoken
