Your case sounds a bit extreme (perhaps it has an element of nocebo through overthinking it?), but I do share this problem to an extent. If you like ambient music, I love Brian Eno’s ‘Reflection’ album and use it for a similar purpose as noise. But I eventually got sick of hearing it again and again, recognising the same bits... Then I found he has also released the original endless generator (from which the album is just an hour-long recording) as an iOS app. It’s wonderful. It’s just endless Reflection, never repeating, always sounding new, but always sounding like Reflection. Expensive but worth it, if you liked the hour-long recording.
