I have it from being a death metal singer/guitarist 30 years ago, but it gets much worse when tired or higher blood pressure (handy though ; most people don't have an actual audible alarm for that). It's indeed not recommended, it is, however very clever how the brain mostly filters it out unless I actively think about it.
I am in my 50s and the most notable 'side effect' is that I must avoid conference calls; it seems unconsciously I got good at reading lips in person, even in groups, but video calls and especially audio calls are just too hard. I tell people now I'm handicapped, which is indeed true I guess; we either meet in person or they will have to write it down. Captions sometimes work, but we work with people from around the world and some English accents just generate mostly random words as captions. Not sure why a discussion about a payment api is mostly about rain, goats, [laughter], [music] and such...
