This study presents a novel composite sound-absorbing structure integrating micro-perforated panels (MPP) with sonic black hole (SBH) configurations to address the inherent limitations of conventional MPP absorbers in low-frequency broadband noise control. While traditional MPP absorbers exhibit narrow-band effectiveness primarily at high frequencies, our proposed design replaces conventional back cavities with SBH structures that leverage unique wave manipulation capabilities – including wave speed reduction and enhanced energy dissipation – to significantly improve low-frequency performance. Finite element model (FEM) is first established to evaluate the acoustic characteristics of individual components (MPP, SBH) and their integrated configuration. Parametric investigations quantify the influence of critical MPP parameters (aperture size, panel thickness, perforation rate) on absorption performance. Experimental validation through impedance tube measurements using the two-microphone transfer function method confirms exceptional acoustic performance: the composite structure achieves multiple absorption peaks exceeding 0.95 and maintains minimum absorption coefficients above 0.6 across wide frequency range. This broadband effectiveness, marked by stable multi-peak absorption characteristics, demonstrates synergistic enhancement through SBH integration. The proposed MPP-SBH hybrid structure exhibits outstanding low-frequency sound absorption capacity while preserving inherent mid-high frequency performance, offering substantial potential for advanced noise control applications requiring broadband attenuation.
