Mechanism of effective depth enhancement and broadband sound absorption optimization in nested resonators with multiple cross-sections

This study presents a class of three-layer nested sound absorption resonators with multiple cross-sectional features, revealing their sub-wavelength characteristics and broadband sound absorption potential through a series of studies. A precise effective depth calculation method has been proposed to...
