📖 The Science of Color Noise & Cognitive Performance
White vs. Pink vs. Brown Noise
White noise equalizes all audible frequencies. Pink noise reduces high frequencies by 3dB per octave for a softer sound. Brown noise drops highs by 6dB per octave, producing a deep bass hum ideal for drowning out chatter.
Why Brown Noise Helps ADHD & Focus
Stochastic resonance theory suggests that low-frequency Brownian sound provides the brain with a constant sensory baseline, reducing restlessness and helping dopamine regulation during mentally demanding tasks.

❓ Frequently Asked Questions
Do I need headphones to listen?
For White, Pink, and Brown noise, regular speakers or laptop audio works great. For the Binaural Beats track, stereo headphones are required to deliver the frequency offset to each ear.
Does this require downloading large audio files?
No! All sounds are mathematically synthesized in real time using the HTML5 Web Audio API directly in your browser with zero data downloads.
Can I leave this running in a background tab?
Yes. Web Audio API continues streaming smoothly even when you switch tabs or minimize the window.
