# The KW-Boundary Hybrid Digital Waveguide Mesh for Room Acoustics Applications

## One-sentence takeaway

KW-boundary hybrid digital waveguide mesh: better room boundaries than naive DWM termination (Murphy & Beeson 2007 TASLP).

## Why it matters here

DWM rooms fail at walls. This hybrid boundary treatment is the practical DWM leftover of the 2007 survey. Anoptic only if you picked DWM; otherwise FVTD impedance (1695) is the serious boundary card.

## Key ideas

- **KW-boundary.** Hybrid termination for DWM rooms.
- **IEEE TASLP 2007.** Harvest waveguide-mesh / hybrid.
- **Fidelity vs naive DWM walls.**
- **DSP mesh culture** (JOS/Savioja), not Yee FDTD.

## Caveats

Still a mesh with dispersion (1761). Not interactive game-scale. Hybrid in the DWM sense, not Yeh wave-ray 2013.
