Aircraft Noise Module

As not every aircraft lands as whisper quiet as this one, SoundPLAN noise modeling is needed! In contrast to the standard aircraft noise models, SoundPLAN makes it possible to depict a comprehensive noise picture of the flight operations around airports. Aircraft taxi, start, and land, but there are also the ground operations of engine run-up, auxiliary power units, carts of rattling baggage containers, air conditioning and traffic sources. ...

Industrial Noise Indoors / Outdoors Module

Industrial Noise indoors and outdoors with Noise Transmission. The SoundPLAN industrial noise modeling is unique. All questions of frequency dependant noise can be simulated whether it is purely an indoor problem, a receiver outside that needs to be assessed for outside sources, or a complex problem with the source inside an industrial building and a receiver on another building. The simulations inside industrial buildings are completely integrated ...


Consulting Services

SoundPLAN GmbH are also consultants for noise control, air pollution assessment, environmental assessment, traffic planning and software development.

Computing Service for Noise Calculations and Air Pollution Studies

Calculation service for noise and air pollution studies. If noise simulations are not the mainstay of your company but a project requires them as accompanying evidence, we can team up with you. Send us the raw data, the geometry and source information and we will create the simulations and return the results in tabular and graphical formats. You can incorporate these findings into your investigation report without the need to have a noise consultant ...
