Objectives

This module of MANATEE software specialized in the e-NVH simulation of electrical machines uses acoustic semi-analytical models to quickly calculate sound pressure fields and results acoustic noise levels.

Summary

This module analytically calculates the sound power level and sound pressure level radiated by the machine based on microphone average position and room reverberation constant, either using Equivalent Radiated Power (ERP) (unit radiation factor, suitable for SM.NUM1), or semi analytic models of cylindrical shells (e.g. equivalent cylinder or disk, pulsating sphere) depending on airbone noise radiator dimensions.
