Sleep log
Your morning sleep log
Take a minute each morning to note how the night went and what you listened to. Over a couple of weeks, you'll see which approach suits you. Estimates are fine. There's no need to watch the clock overnight.
Start with 3 to 5 nights of your normal routine, with no sound or with whatever you use now.
Use one listening approach for several nights in a row and keep logging.
Look at how you rated your nights. Note stress, naps and caffeine too, since they matter as much as sound.
Your progress Example
Averages use your latest 7 nights. These are your own ratings, not measurements of sleep stages.

A better night after a new routine is worth noticing, but it doesn't prove the sound caused it. For relaxation only, not medical advice. If a sound makes your sleep worse, stop using it.
