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.
I’ve tried everything I can get my hands on. For actual silence (or close to it) I wear yellow foam 3m ear plugs and then I wear construction ear muffs, like what you wear to operate loud equipment, over them. Also works wearing them over a small pair of ear buds if you want white noise or music or a podcast. Construction ear muffs are light and made to be worn all day.
I also have a set of sony wh-1000xm5 and they are great for noise cancelling when also listening to music I really like.
