Result
The following figure shows the A-weighted sound power level spectrum including the contribution of stator structural modes to acoustic noise:
- Modal contribution to A-weighted SWL
- plot_aswl_modal_cont
This post processing is very useful to identify which structural modes are involved in noise generation at a given frequency.
