摘要 : The main objective of this study was to obtain an optimal formulation of PU foams with improved acoustic properties by using design of experiment (DOE). With the aim to obtain an efficient acoustic material, the PU foams formulation can be optimised successfully by adjusting the content of various additive components in this experiment. The experiments were conducted with four controllable three-level factors and two target objectives, and Taguchi's orthogonal array L-9(3(4)) had been chosen. The various additive components were: water (3.8-4.8 part by weight), tri-ethanolamine (TEA, 2-3 part
