**v2.01.109** SDLD109 — Calculation of spectra taking into account floor-material interaction
======================================================================================================

**Summary:**

This test case gives an example of the use of the macro command CALC_SPECTRE_IPM [U4.32.12] which allows the interaction of heavy equipment to be taken into account in the calculation of floor spectra. The treatment is validated as a relative or absolute reference point and the correction of the initial state are validated.
