I am much less autistic now, compared to when I was young. I remember some behaviors like picking carpet fuzz and watching spinning plates for hours. I didn't want to be touched. I couldn't shut out background noise. I didn't talk until I was about 4 years old. I screamed. I hummed. But as I grew up, I improved.

The problem you've got is that the kind of materials that absorb noise are difficult to clean. One of the biggest problems in the design of animal shelters is that animals are barking and it's like the sound of a jet plane taking off.
