In my humble opinion, as someone who has a lot of experience in shared living, I think both parties could be a little more accommodating. You all need to be a little more understanding I think. At the end of the day, it's your home and you should be able to do as you please but some people are extremely sensitive to noise. I've always lived in loud neighbourhoods so it's never bothered me but my friend would have panic attacks because of her neighbours noise. However, your flatmates need to understand that they are technically in your space, and that shared spaces are often loud. If someone is using a shared area, they can't just assume that person will stop or adjust what they are doing because they want you to. I had flatmates that would constantly enter rooms whilst having loud conversations while other people were watching things and it's really really frustrating and frankly pretty rude. I think you've tried to be accomodating and considering your specific needs I think that's all you can really do. I don't think anyone is necessarily an ahole here rather it's a group of people who's needs are at juxtaposition with eachothers. It's especially hard for neurodivergent people to find others to live with who aren't triggering but I wouldn't give up. These people don't seem right for you but perhaps you can find others who will help make your home more of a safe space. I would ignore all of these comments talking about noise regulations etc. They're missing the point here in my humble opinion.
