CadnaA is the leading software for calculation, presentation, assessment and prediction of environmental noise. It can be used efficiently at any scale, starting with a few single receivers in a neighborhood up to noise mapping projects of entire countries. This works for various source types in fields of road-, railway-, aircraft-, and industrial noise. 

• highly usable, yet flexible concept
• calculation according to various national, international or user defined standards and guidelines including ISO 9613
• fast calculations even for large projects due to multicore use and 64bit option
• calculation, assessment and presentation of air pollutant distribution
• modeling and calculation of industrial, traffic, and aircraft noise at different scales

• statistical evaluations of noise and other data
• flexible display and result output options
• variety of import/export formats e.g. DXF, SHP or bitmaps from Google Earth
  

• extremely powerful and extensive features for 3D visualization
• absorption and sound power data from user library or existing databases

• print preview output via any Windows ® compatible printer
• standard and user-defined printing
• calculation of noise contours around airports
• roads with track spacing and transverse slope on each point if desired. Bridges, barriers, and embankments
• industrial sources: possible input of sound power level (PWL), sound reduction index (for radiation from buildings), and attenuation (for silencer), single band or frequency spectrum
• train types input from stored global or local libraries, corrections for track type. includes bridges, crossings, and curved track
• auralization: audio playback of cars and trains passing by at selectable emission points
• special sources for power plants and other industries
