- <p dir="auto">This theoretical blueprint presents a tabletop acoustic analog black hole designed to operate at room temperature (298 K), enabling the study of quantum-like phenomena such as Hawking radiation, superradiance, and entanglement in a laboratory setting. The system leverages a 3D-printed gyroid metamaterial structure with a porosity gradient (10–15% per mm) and tunable Helmholtz resonators to create a sonic event horizon (radius ≈ 5 cm). A CO₂-helium gas medium supports stable flow conditions (radial velocity ≈ 280 m/s, rotational velocity ≈ 50 m/s, Reynolds number ≈ 1000), minimizing turbulence. Advanced signal processing, including wavelet analysis, wavelet packet decomposition, entropy weighting, and Bayesian filtering, is predicted to achieve a signal-to-noise ratio of 60–63 dB, resolving subtle phonon correlations (r > 0.9) without cryogenic cooling. Specific predictions include correlated phonon pairs indicative of Hawking radiation, superradiance gain (Γ > 1), and CHSH inequality violation (S > 2) for entanglement, all verifiable through the provided experimental roadmap. Developed by an independent researcher without access to experimental facilities, this untested framework is offered as a practical, accessible guide for experimentalists to explore analog gravity and quantum phenomena. Beyond its primary application, the design may inspire advancements in acoustic manipulation and sensing. The preprint includes detailed fabrication specifications, a FreeFEM++ simulation script, and 39 curated references to support implementation and validation.</p>
