Well, looking at the bigger picture, many here doesnt want to have a kid , not because of the sensory thing, I mean this is something you can work on anyway with your environnement and when you have a kid supposivly you live with someone else right.
Overall, we feel that we dont belong here, that this society isnt made for us , in addition with family dysfunctions , specific social problems and rejection, it pushes you in a corner where you just want/can care about yourself becaus you have no energy/motivation to do more anyway, overwhelmed with your personnal problems, and many of them are created by the problematic interractions we have with society.
I dont think you make the precise decision of not having kids because " they are too noisy", its more like the cherry on top of this cake full of crap that is life especially when you have ASD, than the root of the problem.
And even for NTs society doesnt promote to have kid anymore in the west , its all consumption, self focus on carrier and personal achievements.
This society is more and more toxic for life in general, and people more sensitive like us are maybe first to jump off that train , NT will get it sooner or later anyway. ( I hope.)
Edit : Maybe im projecting my own feeling here, surely, but I think that this is also what many here think.
