VDI 2569 Analysis¶

Introduction¶

The VDI 2569 tab of the Open Plan Office Parameters window displays the parameters for classification of large multi-person offices according to VDI 2569 ¹.

VDI 2569 Level¶

The VDI 2569 Level is the level of sound propagation from VDI 2569 ¹. This is defined as:

This level is a property of an individual path and displayed on the PATHS (ISO 3382-3) tab.

Steps¶

1. Select the VDI 2569 tab in the Open Plan Office Parameters window.

2. In the first list on the left, select measurement paths (defined on the previous tab) to be included in the evaluation. At least three paths must be selected.

3. In the second list, select measurements from the project to include in the T₂₀ reverberation time average.

   Tip

   A dot will appear next to all measurements which are also part of the selected paths from the first list.

   Tip

   VDI 2569 recommends using measurements within 8 m of the source for calculating reverberation time. Distances larger than this will be coloured red.

   Tip

   SELECT COMPATIBLE will automatically select all measurements from the IRIS project where:

   • The measurement is part of a selected VDI 2569 path
   • The measurement is within 8 m of the source

4. The results will automatically be displayed on the right once at least three paths have been selected, and at least one measurement selected for the T₂₀ average.

The room acoustics class is calculated according to:
