“…Compared to the normal density PC concrete, which usually has an acoustic absorption coefficient <0.1 over the range 125 to 2000 Hz [49], GFC exhibits better acoustic absorption properties. The thin GFC specimens tested in this study have lower sound absorption in the medium to high frequency regions than ceramsite porous concrete, which has an average acoustic absorption coefficient >0.5 in this region [50].…”

“…along with a good acoustic performance if properly designed. These consolidated granular materials are also widely used in numerous outdoor noise control applications such as noise barriers (3,4) and in ground surfaces (5)(6)(7)(8)(9). In this context, the need to reduce CO 2 emissions while limiting traffic noise (10,11) has prompted the civil engineering industry to focus efforts on development of new environmentally friendly granular materials while providing similar sound absorbing characteristics.…”

“…Se han evaluado las caracterís-ticas acústicas de concretos, particularmente porosos (Kim y Lee, 2010;Doutres, Salissou, Atalla y Panneton, 2010;Park, Seo y Jun, 2005), celulares, espumosos (Ramamurthy, Kunhanandan e Indu Siva, 2009) y se han comparado con concretos normales. Además, se han realizado estudios relacionados con el aislamiento acústico de muros (Leiva, Solís-Guzman, Marrero y García Arena, 2013), placas de concreto (Pastor, García, Quintana y Peña, 2014) y pavimentos rígidos (Tiwari, Shukla y Bose, 2004). Doutres (2010) evaluó las propiedades acústicas de materiales porosos utilizando el método de tubo de impedancia con tres micrófonos y comparó los resultados obtenidos con otros métodos directos e inversos, entre ellos el método del tubo de impedancia que se usó en esta investigación.…”
