White noise - bright, steady sound that masks everything
White noise spreads energy evenly across every frequency - a full, even hiss, like TV static or steady rain. It's the strongest all-round masker, covering sudden sounds so they don't pull you awake or break your focus.
What is white noise?
White noise contains every audible frequency at roughly equal intensity. Because nothing stands out, your brain has nothing to latch onto - sudden sounds blend into the wash instead of jolting you.
That even coverage makes it the most versatile masker of the noise colors: a chatty office, a snoring partner, a newborn's startle reflex, thin apartment walls. Some people find it a little bright for hours of listening, which is where pink and brown come in.
What people use it for
Covers door slams, traffic and conversation better than any other color.
Evens out a noisy environment so you stay asleep through disruptions.
The steady hush resembles the womb and helps settle a startle reflex.
A consistent backdrop that keeps chatter from breaking your concentration.
