External Noise Import


External noise sources (for instance gear noise or aerodynamic noise, which are not produced by electromagnetic forces) can be imported inside Manatee using an Excel sheet format to obtain a full picture of the system acoustic signature. The resulting overall noise and order tracking analysis can be explored using Manatee postprocessing tools.


The import of external noise helps acoustic engineers to see when electromagnetic noise dominates other sources of noise at each operating point. In automotive applications, NVH engineers can import gear mechanical noise calculated with a third party software to check NVH targets fulfilment per order, and calculate sound quality metrics inside Manatee due to combined e-motor whine and gear whine.
