PLATZER M, Usbeth; INIGUEZ C, Rodrigo; CEVO E, Jimena y AYALA R, Fernanda. Environmental noise levels measurement of the city of Santiago, Chile. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2007, vol.67, n.2, pp.122-128. ISSN 0718-4816. http://dx.doi.org/10.4067/S0718-48162007000200005.
Introduction. A study carried out in Santiago in 1989 estimated that 1,300,000 people were exposed to noise levels unacceptable by international standards. Considering that there are no reports of environmental noise evaluations performed by otorhinolaryngologists, and that the subject has not been reviewed in the past 15 years, in this paper we present up-to-date information on the topic. Materials and methods. Noise levels were evaluated in several places that are part of the common citizen life, disregarding their profession: Residential neighborhoods, parks, discos, pubs, main streets, city buses (old and new system), and subway. Measurements were taken using an integrating sound level meter, according to CONAMA standards, between the months of July and September, 2006. Results. The highest noise pollution was found in discos. With regard to the main avenue in Santiago, Libertador B. O'Higgins, noise levels (80 dB (A)) remained constant in different measured points. As of public transportation, the subway had the higher noise levels (87 dB (A)). There were no differences between the old and new public transit buses. Conclusions. Our results raise an environmental alert, showing that the noise level in Santiago, for most parameters, is above international standards
