Enhanced Low-Frequency Sound Absorption of a Porous Layer Mosaicked with Perforated Resonator
A composite structure composed of a porous-material layer mosaicked with a perforated resonator is proposed to improve the low-frequency sound absorption of the porous layer. This structure is investigated in the form of a porous-material matrix (PM) and a perforated resonator (PR), and the PR is a...
