I wonder if the ANC is actually bringing out latent tinnitus that was already there, but we don't often experience sudden transitions to and from silence where tinnitus becomes most notable. There's evidence that in urban environments street noise is loud enough to cause hearing loss over time. Millennials or younger have basically worn headphones their whole lives as well, and only recently have devices started alerting for dangerous exposure. If you've listened to music or a podcast on a plane or the bus with earbuds then the volume would have been at dangerous levels. I don't want to imply ANC may not cause tinnitus (this should be explored), but I suspect the reason people feel it wares off also has to do with the brain acclimating to background noise again.
