💡 Why use a noise generator?

Constant silence can be just as distracting as sudden sounds. This tool uses real-time sound synthesis to create a consistent acoustic environment that masks intrusive noises, helping your brain settle into a flow state or drift into sleep.

• Boost Deep Work: Drown out office chatter, traffic, or construction.
• Improve Sleep Quality: Create a steady, soothing backdrop that mimics nature.
• Calm Your Mind: Use low-frequency "Brown" noise to soothe an overactive internal monologue.

📘 Pro Tips

• Select Your Spectrum:
• White Noise: Balanced frequencies across the board. Perfect for masking high-pitched distractions.
• Pink Noise: Balanced energy per octave. It sounds like steady rainfall and is often easier on the ears for long sessions.
• Brown Noise: Heavy on the bass. Mimics the deep rumble of a distant ocean or low thunder.
• Set a Fade-out Timer: Avoid the "jolt" of sudden silence. Set the timer for 15, 30, or 60 minutes, and the audio will gently fade away to keep you from waking up.
• Follow the Visualizer: Use the integrated audio visualizer to find your "Zen." The rhythmic pulse provides a calming visual anchor to help you decompress.

🧐 FAQ

Q. What is the difference between these colors? It's a matter of frequency. White noise is "bright" (like static), Pink noise is "fuller" (like leaves rustling), and Brown noise is "deep" (like a bassy hum).

Q. Is this an MP3 loop? No. The audio is generated mathematically in real-time. Because the data is unique every second, you will never hear a "seam" or a repeating loop.

Q. Does it work offline? Yes. Once the page loads, all sound generation happens locally on your device.

📚 Trivia

"White noise" is named after white light. Just as white light contains every color in the visible spectrum, white noise contains every audible frequency at equal intensity. Many people prefer Pink noise for relaxation because its power decreases as the frequency increases, which closely mirrors how we perceive sounds in the natural world.
