Radiated Sound

The Equivalent Radiated Sound utility post-processes the results of exterior structure-borne radiated sound.

This utility contains two parts:
ERP
Post-process the results calculated using Rayleigh’s integral method.
Exterior Noise
Post-process the results calculated using the APML or IE method.

ERP

The following result file types are supported:
  • ERP: H3D and PCH.
  • Radiated Sound (Power/Pressure): H3D.


Figure 1.

Radiated Sound output using Rayleigh’s Integral can be requested for grid points on the structural surface and in the exterior acoustic field. Grid points are used to represent microphones that record the radiated sound, sound power, and sound intensity.

Exterior Noise

The following result file types are supported:
  • Sound pressure: H3D and PCH.
