Abstract: (608 Views)
Background: Porous absorbers are highly effective at attenuating high-frequency noise, yet they face inherent limitations, including reduced absorption at lower frequencies and vulnerability to environmental factors. Combining porous materials with Micro Perforated Panels (MPP) offers a solution but often sacrifices bandwidth. This study deals with optimizing parameters to extend the bandwidth toward higher frequencies, considering health concerns related to high-frequency noise exposure.
Materials & Methods: This study used Finite Element Numerical Simulation (FEM) in COMSOL to model a porous material and MPP composite. It examined parameters like material thickness, air gap, hole diameter, panel thickness, MPP perforation percentage, and layer configurations. The goal was to find the best configuration to expand bandwidth, selecting and fixing the most effective parameter at each stage.
Results: Findings from the simulated model aligned with direct impedance tube measurements. Enlargement of the fibrous material thickness, up to practical limits, expanded bandwidth. Optimizing MPP parameters involved minimizing hole diameter and panel thickness while maximizing perforations. The most effective layer configuration for bandwidth expansion consisted of an air layer, porous material, another air layer, additional porous material, and the MPP layer.
Conclusions: Careful parameter selection can significantly increase bandwidth and absorption coefficients at higher frequencies. The incorporation of MPP enhances the composite's overall resilience, offering mechanical strength, resistance to environmental factors, and aesthetic appeal. The high precision of FEM simulations positions them as a valuable alternative to direct measurements such as impedance tube assessments. This study provides a comprehensive approach to improving porous absorber performance.
