spherical head model

[f-brinkmann]

I'd like to have a spherical head model. For discussion, I would suggest to split the functionality into two function:

• the first function can compute the sound field at any point (scalar, array like) and any frequency (scalar, array like) around or on the sphere, e.g., following Williams (1999) Fourier Acoustics, Sec. 6.10. Scattering from Spheres.
• The second function would parametrize the first function and reference the results to the pressure of a point source in the origin of coordinates.

Would it make sence to add the first method and the seconds as an example on how to use it in this context?
This might lead to easier to maintain code, and less effort in development.

when you say "spherical head" I guess you mean a simple spherical scatterer? I have some code which I wanted to add to spharpy (before I started working on the SphHarm class). But let me know if this is what you're going for and I could start a PR.
