I've got my first good pair with open domes when I was preparing for university. They are still good, and I let my hearing aids be programmed so that the lowest gain setting was the most comfortable, with two directional microphone configurations for different circumstances. But still, the extra noise coming with the additional gain is wearing me out. Perhaps it's some another condition I'm not aware of. I am quite sensitive to noise despite being half deaf with ~50% loss.
Because of our hearing loss we haven't trained our brains to filter out noise the same way people with normal hearing have since birth. So it might be possible to train the brain, but the only way to do that is to feed more sound to the brain.
