Manatee e-NVH software enables to compute the Sound Pressure Level and generate the corresponding sound of your electrical machine. This sound can then be analyzed using Sound Quality metrics to accurately quantify the perceived sound attributes. The following metrics are automatically available at the end of every simulation:
The physical Sound Power level is sometimes not enough to characterize the acoustic annoyance of an electric machine. Some standards therefore use these psychoacoustic indices. Sound quality metrics enable acoustic engineers or NVH engineers to characterize, quantify and further analyze system-level acoustic annoyances.
