Result
The graph shows the overall sound power level of the machine as a function of speed or time.
The red line indicates the speed above which the maximum spectrum frequency is above the frequency of study specified by the user with Input.Simu.freq_spec_max. The green line indicates the speed above which field weakening is applied if relevant.

This graph allows to identify if any acoustic resonance occurs during the run-up of the electrical machine.
