Question 1

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

Accepted Answer

White noise has equal energy at all frequencies (like TV static). Pink noise emphasizes lower frequencies for a more balanced, natural sound (like steady rain). Brown noise is even deeper and rumbly (like distant thunder). Most people find pink or brown noise more pleasant for sleep and focus.

Question 2

Is noise generation safe for my ears?

Accepted Answer

Yes, when used at reasonable volume levels. Start at low volume and increase gradually. Avoid listening at high volumes for extended periods. If you experience any discomfort, lower the volume or take a break. The tool includes a volume slider for precise control.

Question 3

Does it use any bandwidth or stream from a server?

Accepted Answer

No. All noise is generated entirely in your browser using the Web Audio API. No audio files are downloaded and no data is sent to any server. This means it works offline and uses zero bandwidth.

Question 4

Can I set a sleep timer?

Accepted Answer

Yes. Choose from preset timers (5, 15, 30, 60, or 120 minutes) or select "No limit" for continuous playback. The timer shows remaining time while playing, and the sound stops automatically when the timer expires.
