Sound isn't just background - it's a neurological tuning fork. At Heijō, we use specific frequency bands (alpha, low-beta, delta) to design soundscapes that align with the brain's natural states of focus, relaxation, and restorative deep rest.
The Neuroscience of Frequency
Brainwaves reflect the electrical rhythms of your brain and are categorized by frequency. Different bands correlate with distinct cognitive and emotional states:
Alpha waves (8–12 Hz)
Common during relaxed wakefulness. Research shows they increase during meditative states and reduce anxiety by quieting cortical activity.
"Alpha rhythms promote an alert but relaxed state and are commonly observed in meditation and mindfulness practices." - JAMA Psychiatry, 2023
Low-Beta waves (12–15 Hz)
Tied to sustained attention and mental clarity. Often used in neurofeedback protocols for ADHD and focus enhancement.
"SMR training at 12-15 Hz improves sensorimotor control and executive attention." - Journal of Neurotherapy
Delta waves (0.5–4 Hz)
Dominant in deep sleep and recovery. Sound at these frequencies helps activate parasympathetic states.
"Delta frequencies support physiological repair and stress recovery by facilitating deep non-REM sleep." - Neuroscience & Biobehavioral Reviews
Breath + Sound: A Dual Regulator
In Eastern and somatic traditions, breath is considered the "remote control" of the nervous system. When combined with frequency-rich audio, it forms a two-channel entrainment system:
- Sound entrains brainwaves
- Breath entrains heart rate and vagal tone
This synergy enhances emotional regulation and nervous system reset, as shown in trauma-informed breathwork research.
Why We Choose These Bands
Based on studies in neuroacoustics and somatic recovery, we selected frequencies proven to:
- Enhance cognitive flow
- Support emotional resilience
- Promote deep parasympathetic rest
Takeaway: Audio designed for the brain - not just the ears - helps you access deeper states of focus and rest. At Heijō, every frequency is intentional, layered, and optionally breath-aligned for a truly state-aware ritual system.
