Elaboración de un mapa de ruido ambiental diurno de la plataforma territorial 4 - zona norte de la ciudad de Ambato como herramienta estratégica para la gestión del control de la contaminación acústica del GADMA

Abstract

The growth of cities over recent years and the increase of the activities taking place in urban areas have caused a type of pollution that affects the health and human development, it is noise pollution or noise. The present study had as a principal objetive elaboration of a map of environmental noise of the territorial platform 4 -north of the city of Ambato. For this, we obtained environmental noise information (LAeq, Lmax and Lmin) of 21 sample points distributed in the territorial platform. The obtained values were compared with the noise environmental law to establish if in the north of the city fulfills with the parameters established. At the same time, the percentage of measurement uncertainty was calculated using ISO 1996-2: 2007 to establish the possible causes of noise attenuation. Additionally, was register data the wind speed, temperature, humidity and pressure were recorded to determine the spatial climatic variability it affects sound pressure levels in the study area. A Geographic Information System was used for the elaboration the environmental noise map in five schedules the measurement. The noise maps showed that the places located in the downtown area of the platform and the Panamerican Highway, are the most affected with noise levels above 70 decibels. These values are attributed to the high vehicular movement and to the agglomeration of economic activities.
