SoundPLAN Air Pollution

Many planning processes require calculations for noise emissions and air pollution dispersion. It is welcome news to hear SoundPLAN has a uniform software interface for both types of calculations so users can work efficiently in both areas of expertise.

SoundPLAN builds a comfortable bridge between science and engineering: Embedding scientific calculation kernels in the user friendly interface of SoundPLAN and adding specific tools for data control, data conversion and result presentation, SoundPLAN creates an environment for high efficient air pollution dispersion calculation, benefitted from over 25 years of noise programming experience.

Modular Architecture

The modules offered by SoundPLAN are spread from a "simple" Gauss model up to complex prognostic models. The model selection depends strongly on the requested task and the available input data. Therefore the modules can't replace each other. It is not sensible to start with the simpler models Gauss and Austal2000, which were mainly designed for industry licensing procedures, if your work is focused on roads or complex terrain. You should know details about the model borders, before you decide to buy.

Base Module Air Pollution

  • The Base Module Air Pollution generates the environment where all modules are embedded. Besides the basic modules for data input, calculation and result presentation it contains special air pollution library tools which are designed to make your work easy, efficient and transparent.  If you own already a SoundPLAN license, no matter if it is for acoustics or air pollution, the base module is discounted by 50%.

GaussTA Luft'86

  • GaussTA Luft'86 is a model for quick estimations: The formulas of the former German standard "TA Luft '86" are suitable for approximate calculations, e.g. to estimate background concentrations or to make worst case studies, whenever free flow conditions can be assumed around emission sources.

GRAL system

  • GRAL system contains of two programs. The highly recommended Austrian Lagrange particle dispersion model GRAL is suitable to include traffic sources in street canyons. It uses optionally a diagnostic wind field approach or a mixed approach, which can take explicitly buildings into account by calculating a prognostic wind field for a limited area around the buildings. Also tunnel portals can be modeled. To show up its full strength GRAL should be used with pre processed prognostic mesoscale GRAMM wind fields. GRAMM was developed in the complex topography of the Austrian Alps and is capable to regard strongly undulated terrain, and differentiated land use.
  • The first release is again delayed, it will be published in Winter 2013/14.

MISKAM advanced

  • The MISKAM kernel is mainly designed for highly resolved street canyons in urban quarters. The fine grid resolution starts where GRAL ends. Therefore those two models complete each other in a most sensible way. The established, highly recommended and steadily validated prognostic wind field model is ideal for detailed studies, when air movements around buildings suppress thermal effects.

AUSTAL2000 interface

  • AUSTAL2000 is the public domain reference model of the current German directive "TA Luft 02". The model input and output is strictly designed to fulfill the demands of German directives (supports directive 2008/50/EC) and needs a professional interface like SoundPLAN to work efficiently. A more flexible kernel version was announced for 2012 but it is not yet released.

Training sessions

  • Training sessions are offered to assist you in making correct decisions concerning which model to use and how to use the chosen model correctly. If you postpone your decision concerning which module is the best for your work until you attended a training session, you can ensure a correct purchase and wise use of the correct module.
