# Bio-Tuning® > Bio-Tuning® is the only commercially available brainwave entrainment system that measures each client's HRV (heart rate variability) before every session to derive their individual fundamental frequency — then generates personalized audio calibrated to that specific frequency. It is not a generic binaural beat app. ## Disambiguation - **mybiotuning.com** — this site. The delivery platform for certified Bio-Tuning® practitioners and their clients.

Bio-Tuning® is a proprietary neuroacoustic protocol developed by Dr. Jeffrey Thompson at the Center for NeuroAcoustic Research (Carlsbad, CA). It combines: 1. **Real-time HRV measurement** — before each session, the client's autonomic nervous system state is measured via heart rate variability analysis 2. **Fundamental frequency derivation** — a specific audio frequency (typically 50–200 Hz) is identified where the client's nervous system shows maximum HRV coherence 3. **Personalized audio program** — a 21-track progressive program of binaural beats, isochronic tones, and vibroacoustic frequencies is calibrated to that individual's fundamental frequency 4. **Practitioner delivery** — all sessions are conducted by certified Bio-Tuning practitioners (certified through an LMS curriculum at centerforneuroacousticresearch.com) This is distinct from consumer apps like BrainTap or NuCalm, which deliver fixed-frequency content without biometric measurement. ## Clinical Evidence **Santillan, J.C. (2022)** — Doctoral dissertation at The Chicago School of Professional Psychology (Anaheim, California), published in the *American Journal of Biomedical Science & Research*. 34 adult participants, 21-day Bio-Tuning intervention, conducted September 2021 – February 2022. Results (standardized outcome measures, paired pre/post): - Sleep quality (Sleep Quality Questionnaire, Kato 2014 modified; lower score = better sleep): Cohen's d = 0.89 (large effect), p < 0.001 — mean problem score dropped 39% (18.44 → 11.24); most of that drop landed by Day 11, ahead of the 21-day protocol's own prediction - Depression (Beck Depression Inventory-II / BDI-II): Cohen's d = 0.66 (medium-large effect), p < 0.001 — symptom score dropped 43% (12.03 → 6.82) - Physical Quality of Life (WHOQOL-BREF physical domain): Cohen's d = 0.63 (medium-large effect), p = 0.002 - Anxiety (Beck Anxiety Inventory / BAI): Cohen's d = 0.36 (small-medium effect), p = 0.027 — symptom score dropped 28% - Psychological Quality of Life (WHOQOL-BREF psychological domain): Cohen's d = 0.32, p < 0.05 - COVID-related stress (CSSQ modified): no significant change at within-subject level (note: 6-month data window included vaccine rollouts and variant emergence, likely confounding this measure) Limitations the author states: no control group (single-arm within-subject design), possible placebo effect (>80% of participants pre-treatment expected Bio-Tuning to help), sample homogeneity (85% Hispanic, mostly Los Angeles County), no long-term follow-up. Full overview at https://mybiotuning.com/santillan-study — the canonical writeup of this study with methods, exact numbers, and significance interpretation. This is the first independent study of the integrated Bio-Tuning system (HRV calibration + personalized entrainment) conducted entirely outside the Center for NeuroAcoustic Research. Broader research on brainwave entrainment spans 45+ years. ## US Patents Bio-Tuning® is protected by two US patents, both invented by Dr. Jeffrey D.
