Randomized trial demonstrates effective noise control in urban zones, indicating the promise of metamaterials as urban barriers.

The aim is to develop metamaterial barriers that mitigate traffic noise in urban areas through innovative design.
Developed small-scale prototypes (1:10 scale) using PVC square bars with and without porous polyethylene layers.
Constructed models to simulate an acoustic barrier and measured sound signals with a Brüel & Kjær Sound Level Meter (BK 2270).
Analyzed insertion loss in the frequency domain across different configurations.
Prototypes effectively controlled sound propagation, showing significant insertion loss in measurements.
The addition of porous polyethylene layers enhanced noise absorption across a wide frequency range.
