Article Synopsis
- The study explores how grid network structures, while not specifically designed to absorb sound, can still have a significant sound absorption effect due to the gaps between their rods.
- A mathematical model using the one-dimensional transfer matrix method was developed to accurately estimate the sound absorption coefficient by treating the gaps between the rods as spaces between two parallel planes.
- The results demonstrated high accuracy in predicting sound absorption, with a peak coefficient of 0.81 found in samples made from a 3D printer when layered appropriately, indicating the model's practical application potential.
