Those are great!

And glad you like Brain.fm as well :)

To my great surprise, silence is actually the worst performer in our research and for other researchers I've talked to. check out our focus study, and also if you hit the "more" button you can see a kind of bibliography (that we need to organize better).

Silence can be a distraction in itself. Counter-intuitive, I know. I actually think I remember an article about this popping up in my news feed recently, trying to explain why. I was in a hurry so couldn't really read it, but I'll try to find it again after all this craziness dies down :)

But anyway, everyone's different, and different situations call for different tools. When the noise level is just too high for me (like, construction outside, vacuuming, etc) I use those crazy earmuffs meant for gun ranges. A shopvac could be right next to your ear and you wouldn't notice hah
