Brown noise for sleep and focus
Brown noise is the deep cousin of white noise: its energy is weighted heavily toward the low frequencies, so instead of a bright hiss you get a soft, rounded rumble — like a distant waterfall or steady wind. Press play to hear it.

Why people prefer brown noise
Because the harsh treble is rolled off, brown noise feels warmer and less fatiguing than white noise over long stretches. Many people describe it as 'fuller' and more grounding, which is why it has become the go-to for sleep and deep work alike.
Brown noise for focus and ADHD
The steady low-frequency wall of sound masks small distractions and gives a restless mind a constant backdrop to settle against. A lot of people — including many who are easily distracted or have ADHD — find it easier to start and stay on a task with brown noise running.

Is brown noise better than white noise for sleep?
It depends on you. Brown noise's deeper, softer tone feels calmer to many people, while others prefer the brighter mask of white noise. Try both and keep whichever quiets your mind faster.
Does brown noise really help focus?
Many people find the steady low rumble masks distractions and makes it easier to concentrate. It's anecdotal rather than a cure, but it's a popular, low-cost thing to try.
Is brown noise safe to play overnight?
Yes, at a moderate volume. Because the energy sits in the low end, keep it comfortable rather than loud to avoid any pressure-like feeling in the ears.
