Asperger’s Disorder children can have sensitivity to certain sounds. Sudden, unexpected loud noises can be particularly irritating, and the Asperger’s Disorder child with auditory sensitivity will overreact. Barking dogs, alarm clocks, and loud speakers may be upsetting. Noises from motors such as a lawn mower or hair-dryer can be very irritating. Multiple simultaneous noises also can spark a reaction.
Children may be upset by noises in crowds, sudden noises, sirens, and alarms. Reactions such as covering their ears with their hands are often seen. More upsetting reactions seen may be agitation or anger that causes an outburst or emotional shutdown where your child simply refuses to move or talk. Even the classroom with the background noise can be agitating to the Asperger’s Disorder child. While most people can screen out background noise, children with Asperger’s Disorder have great trouble doing so.
Few people can relate to these noises being worthy of much reaction; however, if one imagines that these noises are akin to nails being scratched on a chalkboard, it is easier to empathize with the Asperger’s Disorder child’s aversion to particular noises. Asperger’s Disorder children have trouble ignoring, tuning out, and not reacting to these types of noises.
