I’m autistic with relatively high sound sensitivity. I’m wondering if another autistic person in this community used any soundproofing in an apartment that actually reduced noise coming from a busy street. There are a lot of different products out there and I don’t want to buy something that doesn’t work.
A buddy used to live in an apartment where the amount of road noise made it hard for him to sleep. He added a blackout curtain over his bedroom windows which made a huge difference for him.
