Calculation and Assessment of Interior Sound - CadnaR

Product Code: CADNAR

CadnaR is the powerful software tool for all professionals who deal with noise mitigation at work places or the optimization of rooms under consideration of psychoacoustic parameters.

CadnaR is the powerful software tool for all professionals who deal with noise mitigation at work places or the optimization of rooms under consideration of psychoacoustic parameters.

CadnaR was especially designed for the particular requirements of the following groups:

  • Acousticians.
  • Authorities with responsibility for Immission protection.
  • Architects (construction).
  • Architects (interior designer).
  • Research Facilities.
  • Manufacturers of building acoustics products.
  • Professionals who deal with office design.
  • Designer of electro-acoustic devices.

Intuitive Handling

The software is clearly arranged and intuitive to use. Only the functions which are needed during an active process are visable. At the same time you benefit from the sophisticated input possibilities as your analysis becomes more complex. Focus your time on the project and not on the software. All input and analysis features are easy and intuitive to handle.

Efficient Workflow

Change your view from 2D to 3D within a second. Multiply the modeling speed by using various shortcuts and automation techniques. Many time-saving acceleration procedures enable a fast calculation process.

Modern Analysis

CadnaR uses scientific and highly efficient calculation methods. Techniques like scenario analysis, grid arithmetic or the display of results within a 3D-grid enhance your analysis and support you during the whole planning and assessment process. Sophisticated visualization techniques enable a profound understanding of the correlation between project parameters and calculation techniques.

The primary purpose of the CadnaR demo version is to get an idea about the handling of CadnaR.

  • Calculation of the sound load at workplaces based on the emission parameters specified by the machinery manu- facturer according to the EC guideline 2006/42/EC, and on the room geometry and the room design
  • Specific planning and assessment of noise level reduc- tion measures like change in layout, screening by barriers, sound absorbing claddings of walls and/or ceiling, change of emission levels and more
  • Assessment of alternative scenarios in conjunction with the planning of offices, call centers, public rooms and areas etc.
  • Support when selecting sound absorbing products including cost-benefit analysis of sound absorbing ceilings and wall coverings by an implemented library of sound absorption product data
  • Check of the consequences of alternative planning sce- narios by calculation of the level distribution on a grid
  • Complex room geometries can be modeled (with mirror image method or particle model
  • Directivity of point sources available (in a simplified way or in steps of 5-degrees)
  • Consideration of the reflection/absorption at obstacles
  • Considering the local distribution of absorbers on all room surfaces
  • Input of the frequency dependent sound absorption coef- ficient or selection of a product-specific absorption spec- trum for wall and ceiling areas (also for partial areas)
  • Visualization of the noise distribution in 2-dimensional and 3-dimensional view
  • Voxel grid (volumetric grid) with projection of level distri- bution on x, y and z planes
  • Calculation protocol for receivers
