It would be great to do a study where people learn a technique like meditation to be less "bothered" by noise and see how that affects their biomarkers.
When I turn on the bass, I am in control. I can turn it on when I don't have anything important going on and I can always turn it off. That makes the bass enjoyable. If it's somebody else's bass, then I don't know when it starts, when it ends and whether it will interrupt me. That's the source of frustration for me.
I'm generally fine with monotonous background noise, as long as it's not too loud. There's probably still some subtle passive effect on my health, but I can live with that.
That said, one difference is also that they do use their leaf blowers after they wake up first or are in the mood to do it, so they're not disturbing their own sleep or quiet time.
