Abstract


This paper deals with the optimization of the acoustic properties of samples made of fibrous materials, using biologically inspired algorithms. Samples with a thickness of 10 mm were tested, and the results showed that cotton fibers bonded with polyurethane resin have excellent absorption properties in a wide frequency range. GWO, BW and Puma were used for optimization. The optimization results showed significant improvements in the acoustic properties of the material, opening up possibilities for further application in sound insulation and other relevant areas.


Keywords
