SoundPLAN Acoustics software from professionals for professionals SoundPLAN® sinds 1986.

The core of  SoundPLAN 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. There was/is a need to standardize the prediction models worldwide and engineering groups felt the need to algorithmize the principles of acoustics so that different engineers assessing the same scenario would get reasonably close answers.

Momentarily, with the available calculation power of computers, it is possible to use equations that are becoming more and more complex to better represent the nature of sound propagation in the environment.

Hand calculations are still possible for straight forward situations and can only be used as indications of the expected sound levels.

  • SoundPLANnosie – full version versus SoundPLANessential
  • The available modules that are part of the software suite SoundPLAN
  • The packages that are available for dedicated projects such as rail- and road noise, industrial noise indoor- and outdoor), aircraft noise, and Room Acoustics

Our experienced engineers will be happy to support you with your noise prediction calculations with training and (online) support.

It’s also good to know that there is SoundPLAN Asia based in Hong Kong so even deepest level support is nearby.

SoundPLAN is a modular based software so you only buy what you need and you can always add modules later on.

Our engineers can advise you which modules you can buy to satisfy your acoustical calculation needs.

An overview of all available modules is here.

There are many videos available online in YouTube to give you a better idea of the possibilities of SoundPLAN.

The highlights of SoundPLANnoise at a glance


One software for many areas of application

SoundPLANnoise includes everything from modeling and calculation, to tabular and graphic documentation in various levels of detail to produce informative plans for road and rail noise, commercial and leisure noise, aircraft noise, and ‘Hallin’ (sound propagation indoors).

User-friendly analysis and optimization tools

In addition, SoundPLANnoise offers extensive tools – first and foremost among them is the integrated spreadsheet optimized for your problems. Further tools offer, for example, the optimization of noise protection structures, noise remediation, noise allocation, and noise protection concepts for industrial plants as well as various evaluations (such as the number of affected inhabitants) or the best cost-benefit ratio.

Flexible object definition with varying properties

A special feature of the two calculation modes “road” and “rail” is that even if any of the properties is modified along the course of the road or the railway (e.g. change of speed or bridge addition), there is no need to generate different road or railway segments.

Usage of extensive system libraries

As a SoundPLANnoise user, you have access to extensive system libraries for emission spectra, sound attenuation and absorption, which are regularly updated.

Standardized layouts

SoundPLANnoise, our acoustics software supports your personal project presentation with pre-defined layouts, table and graphic templates, which you can adapt to your own styles.

High computing power for effective work

Our high-performance computing core is our guarantee for a high computing power. If the computing power still should not be sufficient, for example, in the case of large computing areas or very large numbers of sources, it is simple to use SoundPLAN’s distributed computing feature: This shares the computing jobs amongst many computers on your network via automated workflows: the results are then automatically merged again. The size of the computing cluster does not matter. Whether you are using five or five hundred computers: You only need one license for this.
