  "abstract": "By driving the 240‑root E8 lattice with a 132 Hz carrier modulated at the golden ratio φ, we observe emergent acoustic bandgaps that align with specific root‑vector subspaces. The φ‑weighted phase encoding creates constructive interference only for those reciprocal pairs whose sexagesimal representation satisfies a Diophantine constraint, yielding a tunable topological filter. This effect reveals a direct link between Babylonian reciprocal pairs, E8 symmetry, and phononic band structure, enabling a new class of frequency‑selective metamaterials.\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
