Explore the new features of SoundPLANnoise 9.1!

Introduction: The Charm of SoundPLANnoise

In modern urban life, noise pollution has become a widespread problem. How to effectively manage and analyze noise data is a required course for every city planner and engineer. Recently, the release of SoundPLANnoise 9.1 has made this task easier and more efficient. So, what exciting new features does this version bring? Let's find out!

Software Performance Improvements
- 64-bit software version: SOUNDPLAN The noise software is now only available in a 64-bit version, no longer supporting 32-bit versions, eliminating the 1GB data limit on memory allocation during calculations, and increasing processing speed by 15% to 20% (depending on the prediction model).

New Standards and Specifications Support
- ISO 9613-2:2024 standard: Integrates recommendations from ISO 17534, improves the prediction method of sound attenuation during outdoor propagation, enhances the subdivision accuracy for extended sources (line sources, area sources), improves the determination and integration of ground factors, especially for short distances and low heights, and coordinates the general and simplified methods for ground calculations.
- Nord 2000 road and railway standard updates: Modifications to parameters and propagation models, and introduction of a new L max calculation method.
- Norwegian Nord 2000 road implementation: Added the Norwegian Nord 2000 standard applicable to roads.
- Swiss road model: Includes new input data allowing traffic flow input by time period.
- German railway noise model: Added data interface for traffic information database based on German vehicle categories.

Noise Source and Barrier Model Improvements
- Chimney correction: Provides a more effective correction method for chimneys based on temperature and flue gas velocity (for sound speed in air).
- Barrier attenuation and meteorological factors: Introduced a new barrier attenuation algorithm considering the influence of meteorological factors (k meteorological factor).
- Multiple reflections and cylindrical surface reflections: Added detailed descriptions for multiple reflections and vertical cylindrical surfaces (such as chimneys or exhaust pipes).
- Combination of vertical and lateral diffraction of barriers: Provided more detailed specifications for the combination of vertical and lateral diffraction of barriers.
- Consideration of width and height of reflective surfaces: Clarified the standards for considering the width and height of reflective surfaces.

Data Interface and Interoperability Enhancements
- TNM 25 and 31 export support: Added export support for TNM 25 and 31 in the 64-bit version, ensuring compatibility with TNM software.
- Improvements in various export and import options: Including KML export to Google Earth, QSI interface, Shape files, and Accept input, as well as improved preview functionality for DXF import, allowing users to select specific layers for import.

User Interface and Feature Enhancements
- New parameters for map object types: Added options to display attributes as text and allow users to choose whether to show reference lines and their colors.
- Facade noise maps: In version 9.1, it is possible to create contour color lines on facades, providing more detailed noise distribution visualization.
- Industrial building roof options: Added diversified support for industrial building roof shapes, including saddle roofs, single-pitch roofs, and barrel roofs, and allowed users to define the roof shape direction and height.
- Text annotations for sources and receivers: Users can add text annotations of source names or receivers to the map during loading and can move these text annotations.

Other Improvements
- Road and railway attribute reset tool: Added a tool to reset road and railway attributes, allowing users to restart traffic flow assignments.
- Project preparation tool: Before exporting to TNM for calculation, users can use the tool to prepare the project, ensuring no crossing lines.
- Area and percentage display in difference maps: In difference maps, users can see the area and percentage under different noise levels, which helps evaluate the effectiveness of noise barriers and other measures.

Finally, SoundPLANnoise 9.1 provides more detailed documentation and online support, allowing users to quickly find solutions when encountering problems. This comprehensive support system is like having a thoughtful assistant by your side, especially for users less familiar with the software. No more worries about operational errors, truly a great relief!
