Sound absorption of microperforated panel made from polylactic acid (PLA)
The microperforated panel (MPP) is a unique panel that has evolved from the traditional perforated panel. Previously, the perforated panel was mainly used as a protective cover for porous materials. The MPP absorbs sound through the viscous effect around its perforated holes. However, traditional...

| description | The microperforated panel (MPP) is a unique panel that has evolved from the
traditional perforated panel. Previously, the perforated panel was mainly used as a protective
cover for porous materials. The MPP absorbs sound through the viscous effect around its
perforated holes. However, traditional MPPs are typically made from metallic materials that are
not environmentally friendly. In contrast, polylactic acid (PLA) is a biopolymer extracted from
natural resources such as corn and sugarcane. When buried in soil, PLA degrades naturally with
the assistance of soil bacteria and fungi, making it an eco-friendly choice. In this study, 3D
printing method was utilized to produce MPP using PLA as the material. The sound absorption
performance of PLA MPP was compared to steel MPP, which served as the benchmark.
Interestingly, the sound absorption performance of PLA MPP was found to be comparable to
that of steel MPP. This highlights PLA as a viable material for MPP production, aligning with
the global goal of environmental preservation and Sustainable Development Goal (SDG) 12,
which emphasizes responsible consumption and production |
