Abstract
Three-layer microperforated plate is researched. Acoustic impedance of the three-layer microperforated plate is attained according to the equivalent circuit, thus absorption coefficient is attained. Different microperforated plate with different porosity, different diameter, different thickness, different depth of cavity is analyzed and some conclusion is drawn to applied some theory to design these type microperforated plates.
