Open noise barriers for peri-urban environments

Noise as an environmental pollutant in peri-urban environments has become a constant annoyance. Implementing noise-reducing elements to solve this problem is necessary to mitigate noise nuisance and promote the quality of daily life in these areas. This project analyses using trees as scattering elements, using the typology of acoustic barriers based on sonic crystals. Different tree configurations are analyzed using numerical models to determine their effectiveness in scatter sound and absorption, complemented with field studies to validate the models. The results show that specific arrangements and species combinations can significantly reduce noise, proposing a sustainable and aesthetically pleasing solution for noise mitigation in peri-urban areas. This approach offers an effective method of noise control and contributes to the improvement of the ecosystem surrounding these populated areas. Integrating acoustic engineering and ecology principles in this study opens new perspectives in the design of noise barriers, marking a milestone in the search for innovative and environmentally friendly solutions.
