Why does my child keep cupping/covering his ears?

Researchers have not sorted out many of the particular behaviors a child with autism or developmental delay exhibit. In regards to cupping of the ears, or of wearing noise-canceling headsets, some researchers speculate that the nervous system of the child has difficultly ignoring particular background noises. nnExamples not noticing the sound of a fan in the room or the chatter in a restaurant. Many children hear all the sounds equally and this can be distracting to the point of causing anxiety or distress.
