N2 - Glass wool mat is widely used in the fields of building engineering, transport facilities and refrigeration equipment. In this paper, the effect of material parameters such as density, thickness, porosity, and flow resistivity on the normal incidence absorption coefficient has been studied. In addition, fiber length is also investigated to achieve appropriate strength. The prediction error of normal incidence absorption coefficient by modified Johnson-Allard model is less than 5% in the frequency range between 800 Hz and 5 kHz. We could use the modified Johnson-Allard model to determine the parameter of glass wool mat for better development.
