About the sound

What are binaural beats?

A binaural beat uses two nearby audible tones, one per ear. Your auditory system perceives their frequency difference as a beat. Stereo headphones are therefore required for the intended effect.

Frequency guide

Theta · 4–8 HzMemory-related neural activity / lower arousal. Evidence for auditory stimulation is limited and mixed.

Alpha · 8–12 HzAttention regulation / relaxed wakefulness. Around 10 Hz is commonly investigated.

Beta · 13–30 HzGoal-directed processing / active cognition. Around 16 Hz has been investigated for attention.

Gamma · ~30+ HzHigh-frequency neural processing. 40 Hz is experimental; research findings are mixed.

Important

Brain rhythms and audio frequencies are not the same thing. Hearing a 10 Hz binaural beat does not mean your brain automatically switches to 10 Hz. Research on cognitive effects is promising in some studies but inconsistent overall.

Noise & ambience

White noise is spectrally bright and can strongly mask environmental sound. Pink noise rolls off toward the highs and is usually perceived as softer. Brown noise is even more low-frequency weighted and is included mainly as a subjective ambience option.

Research on white/pink noise has found small attention-related benefits in some groups with elevated attention symptoms, but this should not be generalized to everyone.

The Ambience layer adds locally generated soundscapes: coffee shop, campfire, crickets, ocean waves, rain on a roof, rain in a forest, leaves in the wind and birdsong. They are offered as masking/atmosphere options rather than as frequency-based interventions.

Listening safety

The browser cannot know the actual sound pressure reaching your ears. Keep device and in-app volume conservative, especially for long sessions.

Research context

Concept language informed by published work on binaural beats, auditory beat stimulation, neural oscillations and broadband noise, including Garcia-Argibay et al.; Ingendoh et al.; systematic reviews/meta-analyses on white and pink noise; and WHO safe-listening guidance.
