Cochlear efferent feedback and hearing-in-noise perception in autism  

Difficulty in filtering relevant auditory information in background noise is one of the key features of autism spectrum disorders (ASD), and such filtering difficulties can significantly impair a person's social communication abilities. Parents and teachers often report that children with autism have particular difficulty attending to and understanding speech in noisy environments. The researchers in this study will investigate how well adolescents with high functioning autism and typically developing controls filter sound information, including speech and music. Using miniature speaker-microphone earplugs, researchers will measure acoustic signals generated by sensory cells in the inner ear as these emissions are suppressed in the presence of background noise. They will determine if individuals with autism have reduced noise-induced suppression of these emissions, and if such autism-specific differences in emissions are related to auditory filtering capabilities in this population. This research will advance our understanding of how individuals with autism can hear speech sounds in the presence of background noise. Project Status
