These children were the ones least likely to cope with everyday noises. However, other children in the same study had problems distinguishing the loudness of a tone. Some autistic people are sensitive to pitch and a group of British researchers studying autistic children found that 20% had “perfect pitch,” meaning that they have an exceptional ability to distinguish between musical notes. They may like visiting noisy, crowded places or self-stimulate by banging objects loudly. They might enjoy listening to loud music on their headphones. They found that the amygdala (part of the brain associated with social and emotional behaviour) was more active in autistic children than neurotypical children when hearing these sounds.Ī child with SPD may seek out loud noises or crave them. Scientists at the University of California studied the brains of autistic children exposed to traffic sounds and scratchy noises. Many opportunities for socialising involve noisy venues, so this can create real problems when a child with SPD reaches the teenage years and cannot access these places without feeling uncomfortable. It may also affect their social development if their ability to interact with peers is affected. A child with SPD may struggle to filter the relevant noises from the background ones.Īs a result of this, a child with auditory hypersensitivity may have trouble remembering information if it is given verbally. For example, in a typical classroom there may be a teacher talking to the class, but there is also a variety of background noise, like a ticking clock, squeaking chairs, whispering children or outside traffic. The problem occurs in the way that the brain processs the sounds. Unlike deafness, the child has no problem actually hearing sounds. This can also be known as auditory hypersensitivity. It is estimated that as many as 7% of children have a problem with processing sound. How May SPD Affect How Someone Processes Sound? When I discussed visual SPD in the last blogpost, I mentioned that sensory behaviours can be either “seeking” or “avoiding.” The same is true with hearing sounds and we are going to look at how this can impact on everyday life. As previously mentioned, Sensory Processing Disorder occurs when the brain has difficulty with the information it receives via the senses. In this second part of my series on SPD, I’m going to be looking at the different ways that autistic people may process sound.
