In pursuit of the answer, Ingrid Robeyns underwent an exercise involving TV screens within a "gigantic iron head" that approximates the reality of autism. What she learned:

[W]e realized much better that we had to look for strategies to protect him from begin bombarded by sounds, and that we had to intensify our efforts at communicating as clearly as possible. So we now regularly allow/encourage our son to use a headset (to block out outside noises), also in settings where this is considered ‘socially inappropriate’; or we physically take him out of a situation that is exhausting him (family gatherings is a good example – way too much noise and voices and lines of conversations).
