The thing that stood out more to me than the n being low is "the participants reported not previously using noise to help them sleep or having any sleep disorders." Sleeping with pink noise seems like something that you'd end up getting acclimated to.

My n=1 is that I often sleep with a fan on and live in NYC -- whenever I stay in a place where there is no noise I tend to have trouble sleeping, so I end up turning on some nature sounds on my phone from myNoise.

Yeah that seems silly. I was a quiet-room sleeper until I met my wife, who needs some kind of white noise to sleep. I eventually adapted and now sleep much better with noise than without (at least subjectively), but that change took a while, at least several months. I found it quite difficult to sleep with for a while.

I slept without noise for years until I needed it for a while for (reason) and now it feels difficult to sleep without noise. Acclimation’s a real effect

Confounding variable: the presence of your wife may be aiding your sleep more than the noise.
