Development of sound-absorbing pervious concrete for interior applications
2024, Journal of Building EngineeringProposal of numerical models to predict the diffuse field sound absorption of finite sized porous materials – BEM and FEM approaches
2021, Applied AcousticsCitation Excerpt :Granular materials incorporated in lightweight concrete solutions are known to be a valuable solution for outdoor applications since they allow significant sound absorption while still maintaining excellent durability and stability of their properties. These materials have been extensively applied in acoustic solutions, such as noise barriers for traffic noise mitigation [3–10]. However, it is recognized by the scientific community that there is still a need for more in-depth knowledge of their acoustic behaviour and of the micro-geometry influence on noise control solutions.
Improving the sound absorption behaviour of porous concrete using embedded resonant structures
2021, Journal of Building EngineeringCitation Excerpt :Because of these requirements, the interest in lightweight solutions with adequate constructive characteristics for direct application has increased over the last decades. In 2000, Krezel et al. [1] studied the application of porous concrete in noise barriers for urban freeways, while Magrini et al. [2] analyzed the acoustic absorption behavior of multilayer panels with expanded clay. The study of the acoustic properties of expanded clay with experimental characterization and theoretical representation was performed by Asdrubali et al. [3], using the model previously proposed by Horoshenkov and Swift [4] for prediction of acoustic properties of porous granular media with some assumed pore geometry and pore size distribution close to log-normal.
