The Science

Binaural beats work by playing slightly different frequencies in each ear. Your brain perceives the difference as a rhythmic pulse, which can influence brainwave activity. Research suggests beta-range binaural beats (14-20 Hz) may improve focus and sustained attention, while lower frequencies support relaxation and creativity.

Structured background noise (brown noise, pink noise) provides consistent auditory stimulation that can mask distracting environmental sounds and help maintain cognitive engagement — particularly beneficial for individuals with ADHD.

Technology

Built with the Web Audio API for low-latency audio synthesis and Tone.js for generative music composition. All processing happens on your device.
