Tips

FAQ

White Noise Generator FAQ

Find answers to common questions about noise types, playback, and safe listening.

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

White noise has equal energy across all frequencies - a bright hiss. Pink noise has equal energy per octave, so it sounds softer and deeper. Brown noise emphasizes low frequencies even more, producing a deep rumble that many people find most relaxing.

Which noise is best for sleeping?

Most people prefer brown or pink noise for sleep because the reduced high-frequency energy is less tiring. Try each at a low volume and pick what feels most comfortable.

Is it safe to listen all night?

Keep the volume low (well under 50% on most devices) and use a timer if your device supports one. Extended loud exposure to any sound can damage hearing, so moderate volume is key.

Why does the sound loop seamlessly?

The noise buffer is generated once and played in a loop with crossfade-free boundaries because the buffer is self-similar - random noise has no seam, so the loop point is inaudible.

Does the tool record or upload anything?

No. The noise is synthesized in your browser with WebAudio. Nothing is recorded, uploaded, or streamed - the page works fully offline after loading.

Can I use it for a podcast or video background?

Yes, for personal projects. The output is generated locally and not watermarked. For broadcast use, check whether your platform requires licensed audio.
