White noise contains equal energy at all frequencies, creating a consistent 'shhhh' sound like TV static or a fan. It's effective for masking disruptive sounds and helping with sleep and concentration.

What is the difference between white, pink, and brown noise?

White noise has equal energy across frequencies—bright and hissy. Pink noise has more bass, sounding like rain or wind. Brown noise is even deeper, like thunder or a waterfall. Most people prefer pink or brown for sleep.

Which noise color is best for sleep?

Brown noise and pink noise are most popular for sleep. Their deeper frequencies are less jarring and easier to sleep through. Try Deep Sleep, Heavy Blanket, or Womb Sound presets.

Which noise is best for focus and studying?

Pink noise or white noise work well for concentration. They mask distracting sounds without being too intrusive. Focus Zone, Deep Work, and Study Hall presets are designed for this.

Can noise help with tinnitus?

Many people find that noise helps mask tinnitus symptoms. The Tinnitus Mask preset uses a blue-white blend specifically designed to cover high-frequency ringing. Consult a doctor for medical advice.

Is it safe to listen to noise all night?

Yes, at reasonable volumes. Keep the volume at a comfortable background level—if you need to raise your voice to talk over it, it's too loud. Many people safely use noise for sleep every night.
