So that is how surface duct sound propagation looks like.
I don't really understand it wholly but I think I get some idea
.
Would be great if your program were to come with docs or manual explaining stuffs especially explaining the results gotten from the available profiles.
Do you happen to have written such docs? Would be great if you are willing to share them or at least some of them.
The scales they are per pixel? Would be great if they were labeled. Nice job. You're writing a thesis on sound propagation?
