This question really belongs in the parents' forum. There are both autistic and non-autistic parents there.
Also, you need to be more specific about what you are trying to deal with. I'm a mom, believe I am autistic, but fortunately my sound sensitivity is mild - this seems to be one of the more challenging problems for parents on the spectrum.
Taking breaks and asking for help if you can get it is a big deal.
