Evaluación de Emisiones de Ruido, Barrio Valdivia, Guayaquil

Noise pollution is an environmental problem, which affects the hearing processes of human beings and living conditions in the long term. This inconvenience is strongly accentuated mainly in the large metropolises, where productive, commercial, and industrial activities have an intense dynamic, which generates a dysfunctional environment and precariousness of the standard of living in the population. A clear example of environmental contamination occurs in the Valdivia neighborhood, Guayaquil-Ecuador, where the sound pressure levels produced by the influence of noise from automobiles and fixed sources in the sector were recorded and analyzed. The methodology used in the polygon of interest consisted of taking a minimum of 12 sensors with a duration of 5 seconds each, in 9 critical points of the Valdivia neighborhood. Once the average equivalent noise levels were determined, the degree of compliance with current environmental regulations was demonstrated (Ecuadorian official registration document No. 387 04) and it was evidenced that, during the two days, day and night, the noise levels exceeded, in all the critical points, the permissible values, recording maximums of 86.2 dB Ld during the day and 82.9 dB Ln at night, respectively.
