Abstract: This study develops, fabricates, and characterizes a deep sub-wavelength broadband acoustic metasurface for noise absorption. The metasurface is composed of micro-perforated panels coupled with extended-neck Helmholtz resonators, forming a unit absorber referred to as Helmholtz… read more here.
