| Descripción : | Currently, the Secretary of the Environment of the Metropolitan District of Quito has implemented the Quito Metropolitan Atmospheric Monitoring Network with three functional environmental noise measuring stations. In 2016, this state entity summarized in the Environmental Atlas the status of noise levels in Quito and concluded that they met certain undisclosed regulations. On the other hand, a recent study states that during the daytime 25 percent of of the population of Quito is exposed to traffic noise levels above 65 dBA, and 38 percent of is exposed to traffic noise during the nighttime which is a public health risk. This study consists in the compilation and analysis of the acoustic records of five environmental noise measurement stations that the REMMAQ has had from 2011 to July 2018. In addition, the records of the annual Vehicle Technical Reviews are used to correlate the vehicular growth with the evolution of noise levels in Quito. The REMMAQ data is expressed in equivalent continuous sound pressure levels with A weighting (LAeq [dB]) in periods of one hour. From this data, other noise indices were calculated such as Ld, Ln, L10, L90, and LAeq in different time periods. Subsequently, using Microsoft Excel and IBM SPSS Statistics, linear regression studies of the periodically classified noise indices and values of vehicle growth in the city were carried out, as well as comparisons and correlations between their variables. In addition, with permitted photographs of the measurement stations and their surroundings, types of noise sources were identified to justify the calculation results. Finally, conclusions were drawn, and future investigations were projected based on the results obtained. The general conclusion is that the ambient noise levels are above the limits recommended by the World Health Organization, which is an indication of the existence of discomfort and other negative effects on the health of the population of Quito due to environmental noise. |
