Determinación de niveles de Presión Sonora en el área urbana de la ciudad de Loja

Abstract

Abstract: This research work in Loja, Ecuador, focuses on evaluating sound pressure levels in urban areas, especially in commercial and industrial areas. Data were collected from 76 points during three months, using the weighted equivalent continuous sound level (Leq) equation. The results indicate that noise levels exceed the permitted limits at several points in the city, with vehicular traffic being the main source, followed by industrial and commercial activities. The average Leq in Loja is 67 dBA, with a range of 55 dBA (minimum) to 72.9 dB (maximum). In light of this, a mitigation program is proposed with measures such as traffic control, noise barriers, awareness campaigns, and continuous monitoring. The study highlights the need to address noise pollution in urban planning to protect the health and welfare of the population.
