Abstract:
Perforated panel sound absorbers have become one of the most promising passive noise control solutions not only because of their excellent sound absorption performance but also because of their high structural strength and durability. These features make them an interesting eco-friendly alternative to traditional porous fibrous media or foams, especially in those scenarios implying aggressive environmental agents (e. g. strong wind, heavy rain…) or severe working conditions (e. g. turbines, jet engines…). Many engineering applications of these systems can be found in practice ranging from noise barriers and room acoustics conditioning to the design of muffler devices and MRI scanners. This work briefly reviews the fundamentals of classical perforated panel sound absorbers and reports some recent advances in their use for sound absorption applications.

Jesus Carbajo received the B.Sc., M.Sc., and Ph.D. degrees from the University of Alicante, Spain, Miguel Hernandez University of Elche, Spain, and the University of Alicante, Spain, in 2007, 2015, and 2018, respectively, all in electrical engineering.In 2008, he joined the University of Alicante as a Research Assistant and was promoted to an AssociateProfessor in 2018. His research interests are in the field of acoustic (meta-)materials, particularly in the study of perforated panels, ranging from modeling to design and implementation. As an active member of the Applied Acoustics research group at the University of Alicante, his involvement in several multidisciplinary projects gives him a strong background in acoustics and related engineering applications. |
