Abstract
Increases in traffic and the emergent Highway Concession Program created by the Public Works Ministry of the Chilean government, have led to the necessity of providing acoustic protection in inhabited areas in which the level of noise exceeds that allowed by the standard. Around the world, the installation of acoustic barriers has been one of the main measures of the controlling traffic noise. This is the case with the Temuco ByPass Highway, an extension of 21 km, located in a rural area typical of the environment and landscape of the South of Chile. A total of 6000 lineal meters of transparent acoustic barrier (Methacrylate) was installed. This barrier is the first one of its type to be installed in South America, and theoretical calculations and practical results are analyzed in this work. (To be presented in Spanish.)
