El objetivo del estudio fue evaluar la capacidad de la vegetación para mitigar el ruido en el valle de Aburrá. La metodología comprendió dos fases: la primera consistió en la revisión de información secundaria relacionada con dicha función de la vegetación, lo que permitió obtener las bases conceptuales para el posterior desarrollo experimental. En la segunda fase se realizó la medición de los niveles de ruido a 10 m de la fuente sonora (vía de alto tráfico vehicular) en zonas verdes públicas urbanas con diferentes coberturas vegetales (arbórea, arbustiva y arbórea-arbustiva) y sin vegetación. Los resultados no arrojaron diferencias significativas entres los sitios con vegetación y sin ella, lo que permite inferir que en las condiciones del estudio, caracterizadas por contar con unos pocos individuos arbóreos o arbustivos dispersos y poco densos, la vegetación no cumple un papel significativo en la disminución del ruido. Por lo tanto, para su control en zonas urbanas deben tomarse medidas diferentes a la plantación de árboles, o establecer barreras vivas más anchas, largas, altas y densas.
Abstract: The objective of the study was to assess the capacity of vegetation to reduce the noise in the Aburrá valley. The methodology comprised two phases: the first was the revision of secondary information related to the role of vegetation and to obtain the conceptual bases for further experimental development. The second phase was the measurement of noise levels 10 m from the sound source (high traffic road) in urban public green zones with different plant coverage (tree, shrub, and a mixture of trees and shrubs) and without vegetation. Results showed no significant differences between the sites with and without vegetation, allowing us to infer that under conditions of the study, characterized by having few individuals of trees and shrubs dispersed, the vegetation does not play a significant role in reducing noise. Therefore, for its control in urban areas measures other than the planting of trees must be taken, or wider, longer, denser, and higher live barriers should be established.
