Abstract: En el presente trabajo se evaluó los niveles de ruido que perciben las familias aledañas a la zona de estudio en el km 3.5 de la Carretera Panamericana Sur, así como el impacto que generan los árboles mitigando el ruido ocasionado por el transporte vehicular. La metodología consistió primero en caracterizar el área de estudio, la cual presenta barreras acústicas; se dividió en 4 zonas: la zona 1 presenta un dique de tierra, la 2 una pantalla mixta conformada por un dique de tierra con una pequeña pantalla vegetal, la 3 tomada como testigo al carecer de alguna barrera y la zona 4 con una amplia pantalla vegetal; luego se seleccionaron puntos de medición en cada una de las 4 zonas en los cuales con obtuvieron valores de nivel de presión sonoro continuo equivalente (LAeqT) con ayuda de un sonómetro y posteriormente se elaboraron curvas isófonas de forma lateral, frontal y de planta con el software ARCGIS 10.2; también se midieron las condiciones meteorológicas en la zona con una estación DAVIS y el flujo vehicular producido por el tráfico vehicular a través de un conteo manual de los vehículos. Los resultados indicaron que los valores de LAeqT obtenidos en las 4 zonas de estudio se encuentran por encima de los límites establecidos por los Estándares Nacionales de Calidad Ambiental para Ruido (ECA Ruido) para zonas Residenciales. Se concluyó que las barreras acústicas presentes en el área de estudio cumplen la función de amortiguar el ruido y que el tráfico vehicular genera un impacto acústico negativo en receptores.
This work assessed the noise levels perceived by families surrounding the study area at km 3.5 of the South Pan American Highway, as well as the impact generated by trees mitigating noise caused by vehicle transport. The methodology consisted first of characterizing the study area, which presents acoustic barriers; it was divided into 4 zones: zone 1 has a earth dam, the 2 a mixed screen consisting of a earth dam with a small plant screen, the 3 taken as a witness by lacking a barrier and zone 4 with a large plant screen; measurement points were then selected in each of the 4 zones in which equivalent continuous sound pressure (LAeqT) values were obtained with the help of a sonometer and then isophonous curves were developed laterally, front and plantly with ARCGIS 10.2 software; weather conditions in the area were also measured with a DAVIS station and vehicle flow caused by vehicle traffic through a manual vehicle count. The results indicated that the LAeqT values obtained in the 4 study areas are above the limits set by the National Environmental Quality standards for Noise (ECA Noise) for residential areas. It was concluded that the acoustic barriers present in the study area serve the function of dampening noise and that vehicle traffic generates a negative acoustic impact on receivers.
