SoundPLAN - Sound Propagation Modeling Software

SoundPLAN software is developed by Braunstein & Berndt GmbH - Etzwiesenberg 15

SoundPLAN - designing a sound environment

SoundPLAN is an unique modeling and presentation tools, that allowed us to optimize noise control measures and to visualize the effects of noise propagation throughout plants, factories, theme parks or along road and railroad lines.

The software allows the user to visualize the noise situation through an extensive graphical user interface. It also provides:

• traceable propagation models [The propagation models included in SoundPLAN are based upon consistent sets of empirical data. These models allow for noise predictions within a certain level of accuracy. However, it should be noted that although the physics of sound propagation are always the same, the source and propagation parameters can change dramatically. The various models in SoundPLAN allow the user to modify these parameters to match the acoustic environment being analyzed.]
• versatile definition of the sources input [frequency spectrum, time schedule or idle pattern, directivity, mitigation factors, etc.]
• numerous control features for the verification of input geometry and source data.
• graphic tools for the visualization and presentation of the input and output data (i.e., Did the analysis consider this source, the road, this loudspeaker, this building, etc.?), the acoustical hot-spots (i.e., the nature of the problem), the conflicts (i.e. comparisons with governing regulations) and the benefits of various noise mitigation measures.
• noise control optimization features [Which is very important from a financial perspective, e.g., cost versus benefit ratios. For example, 5 dB reduction for a source may cost $30,000 or $60,000 but the overall benefit is insignificant unless other source are reduced in the same way].

SoundPLAN 6.5

SoundPLAN Version 6.5 includes new guidelines for road and railroad noise modeling and new features for distributed computing.

• For road noise the Federal Highway Administration Traffic Noise Model (FHWA TNM ^TM) emission and propagation algorithms from version TNM 2.5 (TM) were implemented. 
  
  Note: The Federal Highway Administration Traffic Noise Model (FHWA TNM ^TM) is protected by U.S. copyright laws. The noise prediction methodology used in SoundPLAN has been designed to be consistent with the FHWA TNM (^TM), however, SoundPLAN has not been tested, evaluated, or approved for use by any Agency of the U.S. Government.

• For rail noise modeling the Federal Transportation Administration FTA noise guideline was converted into a sectional noise model.

• For the Distributed Computing SoundPLAN now support dual processor systems. 

SoundPLAN - Project Manager

The SoundPLAN Wins Manager is the switch board to eight sub-programs:

• Library (Source, material, assessment information)
• Geographical-Database (Geometry)
• Calculation Kernel (Definition of the computation, running the noise or air pollution prediction, Indoor Noise Prediction)
• Documentation (Results Tables)
• Spreadsheet (Generation of Comparison Tables)
• Expert System Industry Noise (Design cost effective noise mitigation)
• Wall Design (Design cost effective noise barrier - walls & berms)
• Graphics (Maps, Colored Noise Contours, 3D Noise Contour Graphic, 3D Topographic Map..)

System Requirements / Recommendation:

• PC Pentium IV 1.4 GHz or faster
• Graphics adapters with a screen resolution of 1024 x 768, 256 colors and 32+ MB (2 MB required) memory
• RAM 1 GB (512 MB minimum)
• Hard disk: 2+ GB
• Printer: laser or ink jet printer with 600+ dpi resolution
• Windows Operating 95/98/2000/ME/XP/NT/VISTA.
