报告英文简介：

In this paper, we propose a forecasting method of the average sound absorption coefficient of the dual-layered nonwoven absorber by employing general regression neural network (GRNN). In experiment section, fifty dual-layered nonwoven absorbers are designed specifically with five different meltblown polypropylene and hydroentangled E-glass fiber nonwoven materials firstly. And then, four structural parameters, thickness, area density, porosity, and pore size of each layer are measured, which will be used as the inputs of GRNN. The average sound absorption coefficient of each dual-layered nonwoven absorber will be calculated and used as the output of the GRNN. The GRNN model exhibits satisfactory prediction results of ten test samples after the GRNN parameter optimization through cross validation.
