Evaluación de los niveles de ruido ambiental en el casco urbano de la ciudad de Tarija, Bolivia
Abstract
El ruido ambiental se ha incrementado considerablemente en la ciudad de Tarija en los últimos años, debido al crecimiento económico y poblacional. El presente trabajo de investigación trata sobre la medición de los niveles de ruido ambiental emitidos en el casco urbano de la ciudad de Tarija, en el cual se pudo comparar el nivel de ruido ambiental con el límite permisible definido por el Reglamento en Materia de Contaminación Atmosférica. El 39 % de las mediciones realizadas excede los 68 dB con valores oscilantes entre 65 y 75 dB, entre los valores excedentes se registró un valor máximo de 100.9 dB generado por el paso de una motocicleta durante una de las mediciones, en las inmediaciones del palacio de justicia donde gran parte de la población espera el servicio de transporte público para desplazarse por la ciudad. Estos niveles producen hipoacusia marcada y severa (comunicación extremadamente difícil), además de perdida de oído a largo plazo. Las principales fuentes emisoras de contaminación sonora registradas durante la investigación son las motocicletas (36%), seguido de bocinas de vehículos (34%), que afectan a la calidad de vida de las personas transeúntes por las calles centrales de la ciudad de Tarija.
Environmental noise has increased considerably in the city of Tarija in recent years, due to economic and population growth. This research Project focuses on the measurement of environmental noise levéis emitted in the urban center of Tarija. It compared environmental noise levels against those permissible by the Atmospheric Contamination regulations. 39% of the measurements taken exceeded 68 dB with oscillating values between 65 and 75 dB. Among the measurements there was a maximum value of 100.9 dB generated by a passing motorcycle, in the vicinity of the courthouse where a large part of the population waits for public transportation. These levels produce marked and severe hearing loss (extremely difficult communication), in addition to long-term hearing loss. The main source of noise pollution recorded during this investigation comes from motorcycles (36%), followed by vehicle horns (34%), which affect the quality of life of pedestrians along the streets of downtown Tarija.
