Option Industry
The industry standard tool for noise calculations.
The all-round solution for urban noise calculations. CadnaA Industry is especially designed for acousticians specialised in industrial installations. Applications range from the calculation of industrial sites, wind farms or mining plants to HVACs, PAGA systems or even open air events.
- Includes all major calculation standards for industrial noise.
- Flexible source input: point, line, or area with advanced emission settings.
- Import emission data easily from .txt or .xlsx files (Lw, Li), stored in a sharable database.
- Define directivity in 2D, 3D, or rotational symmetry—ideal for loudspeaker and event noise modelling.
- Built-in tools to apply A/B/C/D weightings and convert 1/1 to 1/3 octave bands.
Option City
The All-in-One Solution for Urban Noise Modelling.
CadnaA City is the go-to tool for urban and citywide noise calculations involving industry, road, and railway sources. Perfect for strategic noise mapping and urban planning, it combines the full capabilities of CadnaA Industry and CadnaA Road into a single, powerful package.
All calculation standards for noise type Railway included.
- Easy input of railway emissions using train frequency, speed limits, track and bridge corrections.
- Built-in library of predefined train classes across various standards.
- Accurately evaluates combined noise impact from industry, road, and rail sources.
- Supports up to 16 project variants to model different traffic or mitigation scenarios.
Option Road
The professional planning tool for road projects.
For the calculation of road noise CadnaA Road is the perfect solution. Common applications are the evaluation of existing or new roads, the optimization of noise barriers, the calculation of tunnels or even EU noise mapping projects. CadnaA Road includes everything from CadnaA Industry.
All calculation standards for noise type Road included.
- Easy input of road-specific data like traffic volume, speed limits, and surface type.
- Advanced traffic modelling with hourly data, day/night speed variations, and custom road widths.
- Automatic road gradient correction using 3D geometry.
- Compare up to 16 variants for different traffic or noise mitigation scenarios.
Option City & Airport
The complete solution for airport and urban noise planning.
CadnaA City & Airport is the ultimate tool for modelling noise from airports, whether existing or planned and is ideal for large-scale urban noise mapping projects. This version includes all the capabilities of CadnaA Industry, Road, and City, offering a truly comprehensive solution.
Includes one aircraft noise calculation standard, with additional standards available on request.
- Model runways, flight paths, taxiways, APU operations, and engine test areas with ease.
- Built-in aircraft performance and noise database, with support for ANP data and standards like ECAC Doc 29 and ICAO Doc 9911.
- Simple import of radar flight tracks from FANOMOS, used by many European aviation authorities.
Option Basic
The cost-efficient solution for noise projects involving different noise types.
CadnaA Basic is the ideal entry-level option for projects involving industry, road, and railway noise where only a limited number of standards or guidelines are required. It includes all the core features of CadnaA City Professional while offering a more budget-friendly alternative.
- Supports industry, road, and railway noise types.
- Includes one calculation standard per noise type.
- Additional standards can be added as needed.
- Fully expandable with the same options as CadnaA City Professional. Optional EU Noise Mapping Package (Options X and L) for full compliance with the Environmental Noise Directive 2002/49/EC.
- Handle large-scale projects with unlimited objects and advanced post-processing tools.
3D Noise Propagation Made Easy
Easily create 3D models showing noise propagation on terrain and structures. Trusted by customers in over 60 countries, CadnaA is the go-to solution for noise prediction. Our clients include cities, communities, traffic infrastructure authorities, industrial enterprises, engineering and acoustics consultants, as well as universities worldwide.
Unlimited Project Size
CadnaA is built to handle projects of any size, thanks to 64-bit technology, multiprocessor support, and advanced parallel processing. Its extensive library of predefined sound values across multiple calculation standards helps streamline your workflow. From a single main window, you can model and evaluate up to 16 project variants, allowing you to compare different operating scenarios or noise control measures, such as barrier heights, with ease
Overview of CadnaA IndustryEasy Handling
CadnaA uses a “one software, one file per project” approach, making project setup quick and efficient with just a few clicks. The 3D view enables users to visualise sound propagation across both horizontal and vertical planes, offering a clear and intuitive understanding of acoustic impact.
