However, in several large research studies, roughly 65 percent of parents describe their child with autism as showing sensitivity to noise, while smaller studies report that up to 93 percent of people with autism display atypical responses to sounds, including problems filtering sounds. The reported estimates of the incidence of CAPD in people with autism vary widely by report, in part because there is no “gold-standard” or official way of measuring these disorders. May indicate that certain people who haven’t learned language as expected by adolescence may have trouble detecting differences between speech sounds – a skill that’s fundamental for language acquisition.ĭifficulties processing sounds, often described as central auditory processing disorder or auditory processing disorder (CAPD/APD), are particularly common in people with autism.Participants with autism but with no or only minor language deficits produced early brain responses similar to neurotypical participants.People with autism and more severe language deficits listening to names in a noisy background, including other people talking, did not produce the same early brain responses as shown on brain scans as neurotypical participants, when differentiating the sound of one’s own name from another person’s name.Schwartz received a predoctoral fellowship in 2016 funded by Royal Arch Masons International and Autism Speaks.Ībout CAPD: Central auditory processing disorder, or difficulty processing sounds, is common in people with autism
