SoundPLAN Acoustics Modules

Currently available SoundPLAN acoustics modules are as follows:

This module allows 3D viewing of a model including the digitised ground and plotting of results for Grid Noise Map, Façade Noise Map, Meshed Noise Map and Grid Cross-section Map.  Wire frame and solid models can be created and the view point changed by way of zoom, move, tilt and rotate functions.

Three-dimensional animations are an extension of the standard 3D Graphics module.  This module enables the user to create a film sequence of, for example, a train pass-by, with real-time change in noise emission as the source changes position.  "Drive-throughs" can also be created, whereby an animated sequence is compiled which moves along a designated road or other path.  Output can be saved as an .AVI file.

Simulations are in accordance with various European aircraft noise regulations.  The user can input the model, calculate grid noise maps, and combine the results from aircraft noise with the noise from ground-based operations including traffic sources etc.

This module allows the importation of data in the Arcview Shapefile format into the Geo-Database in addition to the exportation of SoundPLAN Geofiles and objects in Shapefile format.

This module enables the user to assess and document noise levels inside a building.  Noise levels incident upon the façade can be calculated inside SoundPLAN or alternatively, user defined noise levels can also be manually entered, meaning that the module can be used independently from the rest of SoundPLAN.  The transmission loss through façade elements is defined and used in the calculation of internal noise levels.  The data are organized in buildings, floors, apartments and rooms.  The scope of this module includes assessing indoor noise levels in a room on a straight façade with one incident noise path to assessing corner rooms exposed to two directions of noise. The module also manages adminstrative tasks such as keeping track of apartment owners and building owners through to knowing the geometry of the apartment.  Scanned plans help identify the location of the assessed room.

This module enables the operator to use advanced graphic features to customise the overall appearance of graphical output.  It enhances the SoundPLAN Graphics module by adding features such as multiple maps on the graphic sheet, overlay of noise contours on bitmap images, labelling of contour lines, additional symbols and text.  The Cartography module makes it possible to generate contour maps from user measured data imported in ASCII format.

This module allows the distribution of large, time consuming calculations to connected computers within a Windows TCP/IP based network.  Time consuming calculations such as Grid Noise Maps, City Noise Maps and Façade Noise Maps can be completed in a fraction of the time when compared to using only one computer.

The advantage of this module is that only the host computer requires the DC license.  All networked computers must have the same version of SoundPLAN installed, including software updates.

 

This module combines all results, propagation and source information into one comprehensive system.  It ranks sources in terms of impact at each receiver and compares cost versus performance for each item, enabling the user to find the best practicable noise mitigation solution.

This module enables the incident sound level to be calculated along the façades of buildings.  The number of receivers per façade and the façades selected are user-definable, meaning you only get the results where you want them.  Façade Noise Map is a flexible tool in that it allows the visualisation of output results by way of a regular map projected on the floor plan or as a rendered 3D model, in addition to producing results tables for each receiver point on each selected façade.

 

The Geographical Database (Geo-database) is one of the core modules of SoundPLAN and is required for developing the 3D noise model.  The Geo-database generates and manages all geometrical data and accepts ASCII, DXF and ESRI Shapefile formats, amongst others.  Even SoundPLAN Geo-files that have been created in other projects can easily be imported.  Data is easily manipulated using the transformation and coordinate operation features.  Objects are easily digitised within the Geo-database and are arranged in a hierarchical order.  One or multiple objects are saved together to form Geo-files.  Multiple Geo-files form Situations. In SoundPLAN Version 7.1, simple single point calculations can now be run and viewed within the Geo-database.

The Attribute Explorer collates all object types and information into one place, allowing the user to easily modify or audit each object.  Objects can be sorted and ranked according to user-definable formulae.

Tunnel openings can now be modelled, with opening geometry and absorption values user-definable.

Noise barriers can now "float" above ground, allowing leakage paths to be effectively modelled and assessed.  Furthermore, wall properties have now been reworked to allow more flexibility in the shape of wall, including curved noise barriers.

3D solid model object view is now available from within the Geo-database.

SoundPLAN Version 7.1 now has an interface with Google Earth, allowing the easy importation of geo-referenced bitmap images into the Geo-database.

This module calculates the sound pressure level over an equidistant vertical grid.  The resolution and maximum height above local terrain is user definable.  The output of the cross-sectional map allows the user to visualise the shadow zone of a barrier or building.  One Cross-sectional Noise Map can be displayed in the graphics, but one or multiple maps can be shown in the 3D Graphics.

This module calculates the sound pressure level over an equidistant grid and graphically presents the output as either grid data or as noise contour lines.  The resultant noise contours or values can be easily exported to ASCII, DXF, ESRI or SoundPLAN Geofile formats.

The noise contour map output allows the user to visualise specific conditions or the differences between two scenarios using the Difference Map.  The Grid Operation function allows corrections to be added/subtracted from grid noise map calculations.

Where the user has access to both the Grid Noise Map and the Façade Noise Map modules, a third noise map, the Meshed Map, automatically becomes available.  The Meshed Map varies the density of grids depending on location/density of objects and is ideal where a noise model includes open space and built-up areas.

 

This module enables the calculation of industrial noise sources (point, line and area) inside a room or factory.  The module enables the user to predict the sound pressure level at specific locations within a room, or produce noise contours for a given floor plan.  The characterisation of a room can also be determined using the Sound Decay Curve function.

The module has been further refined and now features faster calculation speeds when used with SoundPLAN 7, courtesy of hyper-threaded calculations.

The usability and cost-effectiveness of this module is further increased when combined with the Industrial Noise module.  Hall-in to Hall-out calculations allow the complete propagation path to be considered, from inside the factory, transmission through the building façade, and out into the external environment.

The implemented calculation standard is VDI 3760.

 

This module integrates the concepts of internal and external industrial noise propagation into one comprehensive package.  Interior noise levels can either be defined by the user or calculated according to German Standard VDI 3760.  The exterior noise emission is then calculated based on the transmission loss through the Industrial Building façade elements.  The superposition of various façade elements onto any base building façade is easily accomplished.

Noise sources are defined as point, line or area sources in broadband, octave or 1/3 octave spectra, either by the user or from the extensive noise source database built into SoundPLAN.

Implemented calculation standards include ISO9613-2, NORD 2000, CONCAWE, VDI 3760 amongst many others.


 

Enables the user to assign allowable noise emission levels to designated industrial areas.  The aim is to maximise the noise allocation of each area without infringing upon the usage rights of neighbouring noise emitters.

 

Very large projects can be divided up into tiled projects in order to keep loading times, calculation and graphic operations as short as possible.  The toolbox also enables annoyance analysis and conflict analysis to be performed.

 

This module consists of two main components, the emission calculation and the propagation calculation.  The emission calculation is performed internally within the Geographical database, where train quantity, length, speed, and calibration correction are defined.  The propagation calculation is performed inside the calculation core of SoundPLAN.

Implemented calculation standards include CRN, Nord 2000, Kilde Report 130 and SCHALL-03, amongst many others.

The rail noise emission for the entire German rail network was calculated using the calculation core from SoundPLAN 7.0.  To learn more about this, click here.

 

This module consists of two main components, the emission calculation and the propagation calculation.  The emission calculation is performed internally within the Geographical database, where vehicle flow, speed, composition and road surface are defined.  The propagation calculation is performed inside the calculation core of SoundPLAN.

The performance of this module is further enhanced when used in conjunction with Wall Design to design and optimise the location and extent of noise barriers.

Implemented calculation standards include CoRTN, CoRTN Lden, NORD 2000 and RLS-90, amongst many others.

 

This interface enables the user to import Traffic Noise Model (TNM) version 2.5 models into the SoundPLAN Geo-database and also enables the reciprocal importation of geometry and other attributes into TNM.

 

This module allows the user to optimise the configuration of barriers and berms used to control noise.  A pre-calculation of single receiver or façade noise map receivers is used as a starting point, from which the software iterates the height of the noise control wall as per defined section height, until the target noise level is achieved or the maximum number of wall elements is reached.

The optimisation can be based on either the surface area of the wall or cost of construction, in addition to a target noise level.  The module call also perform a cost-to-benefit analysis, allowing the user to easily determine the point at which the law of diminishing returns applies.

This module assists with the selection of windows for a building to enable a noise limit outside a building to be achieved at a specified receiver.

The module is a simple application in a spreadsheet format. If the noise levels at a specified receiver exceed the user defined limit, suggestions are made about noise control for the windows in the building taking into account the size of the façade, the room’s usage as well as the type and size of the window.
