STUDY ON ENVIRONMENTAL NOISE POLLUTION IN THREE AREAS OF THE CITY OF SANTIAGO DE CALI - COLOMBIA

摘要

This article presents the results of a research project to identify the environmental noise pollution in three areas in the city of Santiago de Cali - Colombia. This project was developed by the University of San Buenaventura Medellin by request of the environmental authority of the city "Corporacion Autonoma Regional del Valle del Cauca" (CVC), given that these areas were identified as the most affected by environmental noise sources. This project involved the characterization of the environmental noise sources in each zone, noise mapping in order to quantify the noise levels and the estimation of the people affected by noise at different heights. Based on the environmental noise simulations, the facade exposure levels of the dwellings in each zone were estimated, taking into consideration the noise generated by both traffic and leisure establishments. The contribution of each noise source was assessed with the purpose of determining the predominant noise source in the zones. The results obtained in each area showed that the traffic was the dominant environmental noise source affecting the population in the city of Santiago de Cali.
