The Noise Prediction is available with SOLIDWORKS 2017 SP3. The acoustic Power Level is calculated with Proudman formulae, one of the known steady-state approach in CFD. The Proudman’s formula gives an approximate measure of the local contribution to total acoustic power per unit volume in a given turbulence field.; p9 e1 V+ [. X

This can be used to estimate broadband noise generated by turbulence.
Available results include the Acoustic Power, in W/m^3 and the Acoustic Power Level, in decibel (dB).
