Hi,
I am using Acousto to simulate low frequency room acoustics. I am using the new custombc=2 method for setting the boundry conditions. I have not been able to find a tutorial for this method in the documentation, but I think I have the file syntax correct.
My question is how to convert an absprption coeffecient(alpah) into the gamma value. I followd tutorial 6 equations 6.16, 6.17, 6.18. I inserted the right side of 6.16 for Z in 6.18 with rho=1.21 and c_0=343.
When I try to calculate the gamma value for the example in 6.3.3, I get 0-j3.79, not 0-j23.813 shown in the table. Am I missing something?
Thanks,
Ben

\omega is measured in rad/sec, not Hz.
2pi325*1.21/103.76=23.813
325*1.21/103.76=3.8

Thank you. I figured it would be something basic I was overlooking.
