Resonance — Therapeutic Sound Frequencies
An interactive web app and open knowledge base for therapeutic sound frequencies, grounded in peer-reviewed research, ancient traditions, and cymatics.
The App
Resonance is a single-file, zero-dependency web app that lets you play therapeutic frequencies directly in your browser using the Web Audio API.
Features:
- 9 curated frequency categories with scientific and traditional context
- Single-tone and layer modes — stack multiple frequencies simultaneously
- Binaural beat generation with stereo channel separation
- Per-layer volume control
- Session timer with auto-fade
- Real-time waveform visualizer
Frequency categories: | Category | Frequency Range | Purpose | |---|---|---| | Deep Sleep & Restoration | 2–3.5 Hz | Delta brainwave entrainment | | Meditation & Trance | 4.5–7.83 Hz | Theta / shamanic states | | Relaxation & Stress Relief | 8–12 Hz | Alpha entrainment | | Focus & Cognition | 14–20 Hz | Low beta, GABA elevation | | Neural Coherence & Brain Health | 10 / 40 Hz | Gamma therapy, Alzheimer's research | | Pain & Physical Healing | 26–100 Hz | Fibromyalgia, CRPS, nitric oxide | | Chakra Frequencies | 144–475 Hz | OM spectral analysis | | Solfeggio Frequencies | 396–963 Hz | Ancient solfège scale | | Earth & Cosmic Resonance | 7.83–33.8 Hz | Schumann resonances |
The Knowledge Base
Sound_Frequencies_Knowledge_Base.md is the real heart of this project — a freely available, structured research synthesis you are encouraged to use in your own projects.
It distills 29 source documents spanning:
- Peer-reviewed clinical studies (fibromyalgia, Alzheimer's, pain, bone healing)
- EEG / brainwave entrainment research
- Schumann resonance and geomagnetic biology
- Vedic sound philosophy and Nāda Brahma
- Cymatics and the physics of resonance
- Shamanic drumming and trance research
- Singing bowl therapy
- Solfeggio frequency history and analysis
- Gamma entrainment (40 Hz) neuroscience
What's inside
| Section | Contents |

Highlighted findings
- 40 Hz — 81% reduction in fibromyalgia scores; 53–68% amyloid-beta reduction in Alzheimer's research; activates microglia; drives thalamocortical repair
- 50 Hz — 374% increase in nitric oxide production in endothelial cells
- 7.83 Hz — Earth's fundamental Schumann resonance; documented Zeitgeber for human circadian rhythms
- Shamanic drumming at 4–4.5 Hz produces theta brainwave entrainment consistent across 30,000+ years of cross-cultural practice
- OM chanting produces 7–8 spectral peaks mapping to traditional chakra frequency bands
Use the Knowledge Base in Your Project
The knowledge base is MIT licensed — take it, adapt it, build on it.
Some ideas:
- Build your own frequency therapy app (the raw source data lives in
pdf_texts/) - Train or prompt an AI model with the research synthesis
- Create a meditation or binaural beat generator
- Build a data visualization of frequency-effect relationships
- Use it as a research starting point for a wellness or neuroscience project
If you build something with it, feel free to open an issue or discussion — I would love to see what you make.
Running Locally
No build step required. Just open index.html in a browser:
git clone https://github.com/JTruax/sound-frequencies-knowledge-base.git
cd sound-frequencies-knowledge-base
open index.html # macOS
# or: xdg-open index.html (Linux) / start index.html (Windows)Sources
The pdf_texts/ directory contains the raw text extracted from the 29 source documents used to compile the knowledge base, including studies by:
- Naghdi et al. (fibromyalgia / 40 Hz)
- Iaccarino et al. (Alzheimer's / gamma entrainment)
- Schumann & König (Earth resonance / biological effects)
- Stapleton et al. (meditation EEG, 223 subjects)
- Horowitz & Puleo (solfeggio frequencies)
- Neher & Maxfield (shamanic drumming / trance)
- Rein (DNA repair / frequency)
