Assessment of noise emissions, Valdivia neighborhood, 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; this creates a dysfunctional and precarious environment for the standard of living in the population. A clear example of environmental contamination occurs in the Valdivia neighborhood, Guayaquil-Ecuador, where 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 measurements with a duration of 5 seconds each, at 9 critical points in the Valdivia neighborhood. Once the average equivalent noise levels were determined, the degree of compliance with current environmental regulations was observed (Ecuadorian official registration document N0 387 04). It was evidenced that, during the two days, daytime and nighttime, the noise levels exceeded, in all the critical points, the permissible values, registering maximums of 86.2 dB Ld during daytime hours and 82.9 dB Ln at nighttime, respectively.
