Through the measurement and calculation of the physical properties produced by the deflagration of the gases at the moment of shooting, it is possible to estimate the released acoustic energy. First, the calculation of the angular source energy proposed in the ISO 17201 standard is applied. Subsequently, the estimation of the acoustic propagation in free field is carried out to obtain the sound exposure level. Finally, a field test is performed in order to validate the simulated values. The implementation of the method is compiled in a practical software to automate a quick data loading and obtaining results. El análisis acústico de disparos realizados por armas de fuego permite obtener valiosa información en el ámbito forense. A través de la medición y el cálculo de diversas propiedades físicas producto de la deflagración de los gases ocurrida al momento de realizar un disparo es posible estimar la energía acústica liberada. En primera instancia se aplica el cálculo de la energía angular de la fuente propuesto en la norma ISO 17201. Posteriormente se realiza la estimación de la propagación acústica en campo libre para obtener el nivel de exposición sonora a distancias determinadas alrededor de la fuente. Por último, se realiza una prueba de campo con la finalidad de validar los valores simulados. La implementación del método se compila en un software práctico para automatizar una rápida carga de datos y obtención de resultados. application/pdf text/html http://elektron.fi.uba.ar/index.php/elektron/article/view/60 10.37537/rev.elektron.3.1.60.2019 spa FIUBA http://elektron.fi.uba.ar/index.php/elektron/article/view/60/62 http://elektron.fi.uba.ar/index.php/elektron/article/view/60/105 Copyright (c) 2019 Leandro Sebastián Rodiño http://creativecommons.org/licenses/by-nc-nd/4.0 Elektron; Vol 3, No 1 (2019); 6-9 Elektron; Vol 3, No 1 (2019); 6-9 2525-0159 gunshots; acoustic; forensic science disparos; acústica; ciencia forense Sound Exposure Level in Outdoors Gunshots: Calculation and Experimental Validation Nivel de exposición sonora de disparos en campo libre: cálculo y comprobación experimental info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=60_oai
