Each of our three software products, CadnaA, CadnaB and CadnaR is tailored to its specific field of application.
- CadnaA is the leading software for calculation, presentation, assessment and prediction of environmental noise. Some of the main applications include noise immission studies at industrial plants, noise impact studies of new road or railway schemes or even of entire towns and urbanized areas.
- CadnaB is the software to calculate airborne and impact sound transmission between rooms for an entire building.
- Last but not least, CadnaR is a powerful software tool for the calculation and assessment of sound inside rooms and at workplaces, covering a range of applications from specific planning of noise level reduction measures in production plants to the optimization of rooms under consideration of psychoacoustic parameters.
Besides their individual capabilities, our three software can be also connected to form a powerful package for extended calculations from the outside to the inside and vice versa!
One example that illustrates the workflow would be to know the sound quality inside an office where different types of sources are contributing. From one side, the typical sound sources from an office environment (co-workers speaking, printers, air conditioning). In addition, the noise coming from the outside (roads, industry and other activities). The logical steps are listed below:
- STEP 1 - Environmental noise: Starting from any exterior scenario with sources such as roads, railways or industry, CadnaA calculates the noise levels at the front of the facades of the office building. This building is represented as a special object called CadnaB Building.
- STEP 2- Building acoustics: The noise levels calculated at the facades in CadnaA are automatically synced in CadnaB thanks to the CadnaB Building object. Then, CadnaB determines the transmission through the wall based on building acoustic properties including selected constructions, doors or windows.
- STEP 3 - Interior sound: Finally, CadnaR is used to calculate the level at the receiving room considering the real position of sources, receivers and obstacles. The transmission through the wall is calculated based on the building acoustic properties defined in CadnaB.
The interoperability function is included in CadnaB as a feature, therefore without any additional cost!
