Nature sounds like rainfall & ocean waves vary a lot I imagine, with lots of breaks and pauses, the lack of a continuous sound probably helps.
A fan that's rotating back and forth might produce neurologically better sounds, as the breeze bounces off different parts of the room than one that is fixed in one direction?
Actually hm I just tried a hearing test at https://hearingtest.online (very well done site, read the sidebar notes) and I seem to have a characteristic 4khz dip. I don't listen to music with headphones and have never gone to concerts, perhaps the years of fan noise at night did indeed contribute to this.
