Hospital were noisy places even before the recent pandemic, but the need to save lives have made them even noisier, with potential impacts on patients and staff. In this work, we present a feasibility study on the use of acoustic metamaterials in this context. Acoustic metasurfaces of different geometries, labyrinthine or not, have been tested using a commercial package for finite-element simulations, both separately and in composite combinations. The results are compared and benchmarked with measurements, to optimise the materials' ability to control sound transmission while allowing air to flow through. A discussion on the limitations and the perspectives of this approach completes the study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
