Frequently Asked Questions

What sound types are available?

The White Noise Generator offers five sound types: white noise (equal energy across frequencies), pink noise (deeper, balanced), brown noise (deep rumble), rain (filtered noise simulating rainfall), and ocean waves (rhythmic brown noise with LFO modulation).

Can I play multiple sounds at the same time?

Yes, you can toggle on multiple sounds simultaneously and adjust each one's volume independently. This lets you create custom ambient mixes, such as combining rain with brown noise for a deeper soundscape.

How does the auto-stop timer work?

The auto-stop timer lets you choose a duration from 15 to 120 minutes. Once the timer counts down to zero, all sounds stop automatically. This is ideal for falling asleep without the sounds playing all night.

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

White noise has equal energy across all frequencies and sounds like TV static. Pink noise has more energy in lower frequencies and sounds like steady rain. Brown noise has even more low-frequency energy and sounds like a deep waterfall or distant rumble.

Does this tool require any downloads or plugins?

No, the White Noise Generator uses the Web Audio API built into modern browsers. All sounds are generated in real time directly in your browser — no downloads, plugins, or audio files are needed.
