Hearing in childhood shapes language, learning and development, but scientists still know little about how the hearing system develops or what happens after common ear problems clear up. Two projects follow children over time to study listening development.

What they work on
- Examine whether otitis media (OM), common in early childhood, affects the development of spatial listening and of energetic and informational masking after the ear problem resolves, by following children longitudinally.
- Measure sensitivity to frequency modulation and temporal gap detection in children with resolved OM to track lasting effects on basic auditory perception.
- Model listening and communication development after resolved OM using machine learning, with predictors such as OM history, hearing and cognition, combining laboratory and real-world measures.
- Determine how medial efferent sensitivity to temporal sound fluctuations develops in children, using sweep-tone otoacoustic emissions (OAEs), faint sounds produced by the inner ear.
- Characterize developmental changes in the temporal dynamics of efferent effects using OAE recordings and time-frequency signal analysis, testing the hypothesis that the brainstem shows developmental plasticity.
More about the research
One looks at the lasting effects of ear infections. The other looks at the brain's feedback control of the inner ear.
Why it matters
Evidence that children have lasting listening deficits after otitis media could support earlier identification and intervention for children whose hearing was affected. This could inform audiology, pediatrics and speech-language care. OAE-based measures of efferent function could become objective tests of hearing, may help predict susceptibility to noise-induced hearing loss, and could guide better hearing-device algorithms.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
