Bugfix

Besides many new functions, version 2022 MR1 also contains bugfixes which may have an influence on calculation results, see below in the section "Bugfixes". Due to these changes, we strongly recommend an update, which is available on our website (after login).

New Features

  • DIN 4109: Implementation of a combined evaluation parameter R'w|Dn,w with automatic assignment depending on the partition area (Calculation | Configuration | Transmission airborne noise | R'w|Dn,w).
  • DIN 4109: Adaptation of the requirements according to DIN 4109-1:2018-01 and DIN 4109-5:2020-08 to the evaluation parameter R'w|Dn,w.
  • New dialog "Room/habitation assignment" in the “Project” mode for optimized assignment of rooms to habitations (Tables | Room/habitation assignment).
  • The selection of the habitations for editing the habitation assignment can be done directly via Multiselect and the context menu in the 2D view.
  • New 2D habitation display when selecting habitations in "Project" mode.
  • Implementation of a result table in the “Results” mode for the clear representation of transmission situations with an export as well as different filter functions (Tables | Result table).
  • Implementation of calculation presets that can be performed using the "Calculation presets" icon in the result table as well as in the lower part of the list box in the “Results” mode.
  • Start a specific calculation for habitations or rooms using the context menu in the "Project" mode.
  • DIN 4109: Direct output of values for the DEGA 103 sound insulation certificate from the result table.

Bugfixes

  • DIN 4109: The partition area Ss was corrected to the gross area when calculating the flanking transmission in buildings.
  • DIN 4109: The vibration reduction index for junction typ 48 and 51 is now calculated using the method for Kij,min.
  • DIN 4109: When verifying the exterior components, the correction KAL is already taken into account in the requirement (Requirement DIN 4109-1:2018-01).
  • Adjustment of copy and paste logic for elements in “Constructions” mode.
  • Bugfix in partition area determination of not rectangular ceilings.
  • The net area of the partition is now also influenced by small components and elements (shutter box and air intake).
