| description | The effect of urban trees as a noise mitigating element was determined on Alameda
Avenue in the city of Talca, Chile, a Mediterranean continental area. Maximum and
minimum noise, especially generated from vehicles, was recorded at 13 points in four
sections of the avenue for twelve days, three times a day at different distances from
the edge of the street way, which generated a total of 2,080 noise records. At each
point a circular plot of 201 m2 was established to determine tree and shrub coverage.
The results showed significant differences of noise between the classes of coverage;
however there was no relationship significant between the noise level and the increase
in coverage, which can be explained by the large amplitude in the noise registers. The
vegetation located at 6.5 meters from the sound source shows lower levels of noise
when the coverage is increased, proving the environmental function of the vegetation
in the mitigation of this pollutant agent. Regarding theses of the findings, it is necessary
to implement public policies that consider urban planning, incorporating in its design
greater and better availability of tree species and that certain public space are located
away from sources of noise pollution. |

Se determinó el efecto del arbolado urbano como elemento mitigador del ruido en la avenida Alameda de la ciudad de Talca, Chile, ubicada en el área continental. Se registró durante 12 doce días el ruido máximo y mínimo, especialmente proveniente del tránsito vehicular, en 13 puntos en cuatro secciones de la avenida, en tres horarios durante el día a diferentes distancias del borde de la vía, generándose un total de 2.080 registros de ruido. En cada punto se estableció una parcela circular de 201 m2 para determinar la cobertura arbórea y arbustiva. Los resultados mostraron diferencias significativas entre las clases de cobertura, sin embargo no se observó una relación significativa entre el nivel de ruido y el aumento de la cobertura, lo que se puede explicar por la gran amplitud en los registros de ruido. La vegetación ubicada a 6,5 metros de la fuente sonora muestra menores niveles de ruido cuando se incrementa la cobertura vegetal, comprobando la función ambiental de la vegetación en la mitigación de este contaminante. En consideración a los hallazgos, es necesario implementar políticas públicas que consideren una planificación urbana que incorpore en su diseño mayor y mejor disponibilidad de especies arbóreas y que ciertos espacios públicos, como el estudiado, se localice alejado de las fuentes de contaminación acústica.
