Project work and data management

Data input

  • Import of geometry and technical data through different data interfaces
    Formats: DXF, ASCII, TXT, ArcGIS (shape)
  • Project-based work on a graphical user inter-face with GIS functionality
  • User-friendly management of project data, results and grids


  • Definition of variants for calculating case studies, scenarios, planning versions

Editing and visualizing objects

  • Element database with display of technical data
  • Edit, delete, change, copy, join, split and move single or multiple elements using the mouse
  • Design tools and macros: build dams or cuts, generate reception points automatically, transform elements, draw free body diagrams of altitude lines, count kilometers, generate circular buildings and parallel elements
  • Thematic maps for graphical representation and monitoring of input data

Special functions for industrial noise

  • Databases for sound emission values, transmission and absorption losses, meteorological annual statistics and time series
  • Macro for generating 3D structures, e.g. buildings with noise-emitting walls for calculating industrial noise
  • Multiple reflections up to the 50th order
  • Input and calculation of linear or A-weighted cumulative, octave band and third octave band levels
  • Room conditions according to EN 12354-4

Checking and testing functions

  • Plausibility and geometry checks, clearly arranged lists of the data entered and graphical functions are available for checking the input data
  • Conformity with DIN 45687 – fulfilling test tasks
  • Estimate the inaccuracy of results in case of optimized calculation models

Calculation model

Single points, reception grids and façade levels can be easily calculated, while sophisticated algorithms provide for short calculating times.

  • Calculation according to reference (strictly as per directive) and optimized calculation model
  • Automatic segmentation of line and area sound sources
  • Compliance with standard-specific distance criteria

Calculation Control Center (CCC) for performing the calculation

  • Central management of all calculations at single points, in the grid or on façade points
  • Automatic calculation jobs by means of batch job control; calculation of single points, grid and façade levels as well as of all project variants in one go
  • Integrated management and registration of the results calculated
  • Powerful variant management to allow studying planning scenario

Single point calculation

Results are saved in lists with varying itemization degree:

  • Short lists: Overview of reception point and/or rating levels for all rating periods. Comparison of results with guidance values
  • Mid-size lists: Contribution of each single sound source to the total noise impact level, identification of main sound sources and frequency contents
  • Long lists: Detailed and testable summary of all in fluencing variables, intermediate and final results

Grid calculation

  • Simultaneously calculate all rating periods (day, evening, night, resting, etc.)
  • Generate differential grids (logarithmic and energetic)
  • Create conflict maps and population equivalent values
  • Export noise maps as contour areas to ArcGIS, ASCII or binary ArcGIS files, DXF

Documentation and presentation

Report manager

The report manager function provides a powerful tool enabling users to design printouts and reports according to their individual needs and in many versatile forms.

  • Predefined paper formats and page layouts (from size A4 to size A0 in portrait and landscape formats) or individual formats
  • Various layout components for structuring the printout as desired: plan/grid, text, graphic, color legend, element legend, header and footer
  • Use of text boxes and plan clippings that can be designed as desired
  • Numerous options of labeling the axes and contour lines and displaying the scale
  • Parallel output of all point, façade and grid results

3D viewer

The powerful 3D Viewer allows moving through the 3D model in three different settings.

  • Profile sections, screenshots and video recordings
  • Automatic flight along line elements
  • Graphic symbols for roads, vegetation, traffic light, vehicles
