SoundPLAN GmbH

- Noise Control and Noise Mapping Software


Stay ahead of your competition with noise modeling software from the world market leader! Under the menu topics SoundPLAN Acoustics and SoundPLAN Air Pollution you can find detailed information about the two branches of hte SoundPLAN software. Our software comes in two flavors:SoundPLAN, the full industry strength software andSoundPLANessential, the software for the occasional user.

SoundPLANhas the full industrial strength, the full flexibility and the full modular design.SoundPLANessentialwas designed with the occasional user in mind, who wants the full processing power ofSoundPLAN, but does not want to deal with the complexity of a fully flexible, modularly designed software.SoundPLANessentialcombines the legendarySoundPLANcalculation core with a single document input editor to provide a program that has no artificial limitation on job size, but is quicker to learn, and for standard cases, provides striking results in a very short time.

With combining innovation, a fully integrated suite of indoor and outdoor noise modeling and air pollution evaluation, user friendliness and  the best Graphics and Reports,SoundPLANhas been leading the market for almost 30 years. With our proven development team we will lead the way into the future. Many innovations were designed bySoundPLANand were copied by others. Like in many cases, the original is better than the copies! AsSoundPLANdoes not impose any artificial limit in project size, there are no hidden surprises when all of the sudden the maximum project size is reached and it costs more than the original cost of the software to lift this limit.SoundPLANis the only software without any artificial restrictions in size or the number of objects that can be processed! Avoid costly retrofits and start directly withSoundPLAN.


SoundPLANhas been on the market since 1986. It enjoys the largest number of noise simulation software users worldwide. The complete integration of indoor factory noise, transmission through walls/floor slabs and the noise propagation into the environment make this software the ideal tool for engineers working in the fields of noise planning, noise in the workplace, noise mapping and as part of general environmental assessment studies. The unsurpassed numerical and graphical presentations make it easy to explain your findings to the public and to agencies requesting a study.

SoundPLAN, because of its integration of noise and air pollution modules, makes interdisciplinary work in planning easy. Many modeling objects are shared between the air pollution and noise models.

SoundPLANhelps you to work efficiently by offering templates for graphics, tables and spreadsheets, and by hosting all acoustics and air pollution relevant data in libraries that can be shared between users. Importing and exporting data in various formats make it easy to reuse data from external sources. The more you can import data, the faster you can proceed with the creative work of reducing noise in the neighborhood.

SoundPLANis marketed worldwide via a network of dedicated trading partners. Currently more than 25 trading partners are active. Check our list to find information about the SoundPLAN representative in your area. If you live in an area without a distributor, contact SoundPLAN International LLC in Shelton, Washington, USA.

SoundPLANis now available as the version 8.0 as native 64 and 32 bit versions. Both versions can be installed concurrently on the same PC, the 32 bit version is fit for all but huge projects. As long as Google Earth is only available as a 32 bit version, only the 32 bit SoundPLAN version can interface with this software. External Web Map Servers with many readily available maps augment what Google Earth, Google Maps and Open StreetMap offers.

Software from professionals for professionals

SoundPLAN was one of the very first noise modeling softwares on the market, debuting in 1986. Due to its ever increasing popularity on the world market, an international office was opened in 1999. The core of our business was and is the prediction of noise in the environment. Noise emitted by various sources propagates and disperses over a given terrain in accordance to the laws of physics. Worldwide, many governments and engineering associations felt the need to algorithmize the principles of acoustics so that different engineers assessing the same scenario would get reasonably close answers.

When the first standards were introduced, computers were not available for everyday noise calculations, so the equations were simplified for hand calculations. Some of these standards, designed 30 years ago, are still in use today. Over time, generations of researchers have measured noise and developed different interpretations of cause and effect, so the equations are becoming more complex to better represent the complex nature of sound propagation in the environment. The calculations have become so complicated and time consuming that the use of computers is paramount. Hand calculations and rough estimates with spreadsheets are a thing of the past. Our website tries to show the ever more complex world of physics and how our software solves complex problems automatically to free the consulting engineer's mind so he can solve the creative part of noise planning. Trusting routine tasks to the software allows you to concentrate on your plan and how to present your findings to municipalities, environmental administrations and private and government bodies from research to planning.

Modular by design
Noise control consulting projects are very diverse in scope. Different jobs require different tools. To accommodate this, SoundPLAN has a modular design where you -the user -  purchase only what you actually need. If a new project requires a tool you need, you can order it via e-mail.

SoundPLAN International LLC will generate the new license file with the new tool and send it to you attached to an e-mail. Over 95% of the orders ship the same day they are placed.

If you want to read about individual modules, please see the list of modules on the right side of the menu area.

Following is a list of acoustic modules for an overview:

  • The base module: SoundPLAN Manager, Geographical Database, tabular Documentation, Spreadsheet, basic Graphics, DXF and ASCII Interface
  • The noise modules: Road Noise, Railway Noise, Industry Noise, Indoor Factory Noise, Aircraft Noise
  • The Graphics: Grid Noise Map, Grid Cross-sectional Noise Map, Façade Noise Map, Cartography, 3D-Graphics, 3D-Graphics Animation
  • The tools: Wall Design, Expert System for Industry Noise, Windows Dimensioning, Distributed Computing, Noise Mapping Toolbox, Building Acoustics Outside, Noise Allotment, ArcView Interface, TNM Interface
