Mathematical analysis reveals that Fibonacci audio frequencies form an inharmonic series governed by the golden ratio, suggesting alternative acoustic tuning models.
FINDING: Fibonacci numbers (89, 144, 233, 377, 610, 987 Hz) used as audio frequencies produce a sequence where each term is approximately φ (1.618) times the previous, creating an inharmonic series based on the golden ratio rather than integer harmonics. MATH: - Frequency sequence: f_n = Fₙ₊₆ Hz, where F_n are Fibonacci numbers (F_11=89, F_12=144, F_13=233, F_14=377, F_15=610, F_16=987, F_17=1597 ≈ 1.60 kHz). - Ratio between consecutive frequencies: fₙ₊₁/f_n → φ = (1+√5)/2 ≈ 1.6180339887. - Inharmonic series: Unlike harmonic series (1:2:3:4...), this is a geometric series with ratio φ. - Binaural beat at exactly 1.618033 Hz is claimed, which is φ Hz. CONNECTION: - φ appears directly as the frequency ratio and as the binaural beat frequency. - The sequence 0.618 (1/φ), 1.618 (φ), 2.618 (φ²) are all present as ratios between non-adjacent terms. - No explicit link to base-60, crystallographic symmetry, or root systems in the provided findings. - The paper (arXiv:25 Author: Andrew Stewart Caldin, Independent Researcher, UK.
