Tips for Best Results with Our Noise Generator
Use brown noise for sleep
Brown noise has the deepest, most rumbling character — like a distant waterfall or gentle thunder. It is widely reported as the most soothing noise color for falling and staying asleep.
Use pink noise for focus and study
Pink noise balances low and high frequencies naturally. Research suggests it can improve focus and concentration by providing a steady, non-distracting background.
Use white noise for sound masking
White noise covers all frequencies equally, making it effective for masking sudden environmental sounds like traffic, conversations, or office noise.
Start at a comfortable volume
Noise should be loud enough to mask distractions but not so loud that it becomes fatiguing. Start at 60-80% and adjust to your comfort level.
Frequently Asked Questions About Our Noise Generator
Is this noise generator really free?
This workflow is available through Magica; access and usage follow your Magica plan.
What is the difference between white, pink, and brown noise?
White noise has equal energy across all frequencies — it sounds like a bright, even hiss. Pink noise decreases in energy at higher frequencies (3 dB per octave), producing a warmer, more natural sound. Brown noise decreases even more steeply (6 dB per octave), resulting in a deep, low rumble similar to thunder or a waterfall.
Which noise color is best for sleep?
Brown noise is widely considered the most soothing for sleep due to its deep, low-frequency rumble. Pink noise is also popular for sleep and has been studied for its ability to improve sleep quality. Try both and see which works best for you.
Which noise color is best for focus?
Pink noise is often recommended for focus and concentration because it has a balanced, natural sound that is less fatiguing than white noise over long periods. Brown noise also works well for creating a calm, non-distracting background.
What audio format is the output?
The generated noise is saved as a high-quality WAV file — lossless quality suitable for any audio application.
Can I use the generated noise commercially?
Absolutely. The noise is generated mathematically in your browser. There are no licensing restrictions — use it however you like.
Is my data uploaded to your servers?
No. All noise generation happens entirely in your browser. No audio data is sent anywhere — your privacy is fully protected.
Can I use this on my phone?
Yes! The noise generator works on smartphones, tablets, and computers. Just open it in your browser. Performance is fast on all modern devices.
Can noise help with tinnitus?
Many people with tinnitus find that noise masking — especially white or pink noise — helps reduce the perception of ringing or buzzing. It works by providing an external sound that blends with and partially covers the tinnitus. Consult a healthcare professional for personalized advice.
Why is brown noise called 'brown'?
Brown noise is named after Robert Brown and Brownian motion — the random movement of particles in a fluid. The noise is generated by a random walk process, not because of the color brown. It is also sometimes called red noise or Brownian noise.
