Code validation

[Toktom]

Hello I'm Michael the developer of this small project that is just the implementation of some of the models that are use to find the sound absorption coefficient and I'm looking for help.
I implemented the models and so far so good. But I need help to validate that all implementations are correct. So, I need people to test the code, check for errors (within the mathematical formulations I implemented) and also suggest improvements to the project, models that could still be implemented, among other related things.
So, if you have tested the code, I ask you to leave your feedback below.

Hello, i just see your code and i propose you to help you for the developpment.
Do you know the transfer matrix method to compute absorption of element with and without air gap or slotted panel for example?

Hello @bfrax, thank you for your comment.

Yes, I do am aware of those methods but didn't implement them myself. A fellow acoustical engineer has been working in a package focused in estimating the sound absorption using the transfer matrix method, you can access his project with the link below.
