Pink noise, for sure. Actually, I thought Pink was supposed to be acoustically flat, frequency-wise, so perhaps I’m confused with Grey?
I used to live at a residential intersection, and would regularly find myself awake and not sure why. Turns out some cars loved to roar past, waking me up, but by the time I was aware they were past and I didn’t remember the cause. White (then pink) noise, from the excellent MyNoise.net and later app, helped cover that, and I’ve been using it to sleep better for the past 7 years.
I agree that White is too harsh. Brown is too low for me, I need more volume at higher frequencies to cover the occasional higher outdoor sounds. Lol @ Blue & Violet, I wonder where they’d be useful!
