Abstract

A combination of a hexagonal lattice of close cylinders and a metasurface containing Helmholtz resonators (HRs) is presented in this contribution. The arrangement has been optimized to enhance sound absorption of plane waves arriving at a wide range of incidence angles. In room acoustics, this is useful for adapting the absorption performance to realistic sound field characteristics.
