DEVELOPMENT OF MICRO-PERFORATED PANELS (MPP) AS WIDEBAND SOUND ABSORBERS: COMBINATION OF MULTI-LAYERED PANELS AND INHOMOGENEOUS PERFORATIONS
Micro-perforated panels (MPP) were first formulated by Maa to improve on the shortcomings of conventional sound absorbers as the result of fibrous material usage. However, their Helholtz-resonator-based absorption mechanism provides only a narrow bandwidth near the resonancy frequency of the MPP. Th...
