Hello Could anyone let me know whether it is possible to input the Sound Absorption Coefficient of a newly created material in ANSYS Harmonic Acoustics?
I am trying to find out which has the best noise reduction ability out of a set of materials, and so far I only have the Densities and the frequency based Absorption Coefficients of the materials.
So can I directly give the absorption coefficients into ANSYS?
If not, could you please suggest possible alternatives to complete my requirement.
Many Thanks in advance! :)

You can define the frequency-dependent absorption coefficient using the absorption surface:
