PARAMETRIC STUDY ON THE SOUND ABSORPTION PROPERTIES OF 3D-PRINTED OCTET-TRUSS LATTICE STRUCTURES
Original language description
Noise is a significant environmental factor that must be eliminated by appropriate means. This study investigates the acoustic insulation properties of 3D-printed porous materials with an octet-truss lattice structure, fabricated using fused filament fabrication (FFF) technology. The sound insulation performance of the tested materials was evaluated based on the frequency dependent sound absorption coefficient, which was experimentally determined using an acoustic impedance tube. In this work, several parameters affecting the sound absorption properties of the investigated lattice material structures were systematically analysed-, including volume ratio, sample thickness, excitation frequency, and the presence of air gaps. Based on the findings, specific recommendations are proposed to enhance the sound absorption characteristics of the octettruss lattice structures and thereby reduce unwanted noise.
