Directivity

In CadnaA, the directivity of sound sources can be considered either by predefined directivities for certain source types (e.g. stacks) or by user-defined directivities.

On the dialog of all industrial sources (point, line, area sources) a button „Directivity“ is available. On the Directivity dialog pre-defined and entered or imported directivities can be selected. By default, all source types mentioned above have no directivity addressed.

The directivity correction is added in the calculation of the emitted sound power.
