| Abstract: | Statistical models, using central composite
rotatable experimental design, have been developed to predict sound
transmission loss of jute needle-punched nonwoven fabric based on the three
important parameters, namely needling density, depth of needle penetration and
mass per unit area. From this model and its contour diagrams, the simultaneous
effects of these parameters can be understood and prediction of sound
transmission loss can be made knowing the values of independent parameters. The correlation coefficient between observed and
predicted values is 0.94. The maximum sound loss is achieved for 14-15 mm depth of needle
penetration, whereas the minimum sound loss is observed for area density 650
g/m2 and punch density 180 punches/cm2. |
