Hello everyone ,
The situation is I have a problem that can not find a way to do it.
In the article I have attached below. Figure 3 Spectral Sound Pressure Level Directivity.
I'm doing the theme of sound survey 0.9m diameter propeller. I really like picture number 3 but do not know how to draw it.
Can you help me? Please!!!!
