> I can't understand anything if more than one person is talking at the same volume. Maybe that's just normal and I'm bad at lip reading, though.

I want to say it's normal, but it's also known as sensory or auditory processing disorder and it's not uncommon in neurodiverse people. Learning some lip reading or just observing someone's mouth movements helps me in those situations, but it's far from ideal.
