Overview of CadnaR for industry acoustics

Noise

CadnaR provides powerful tools to efficiently manage any scenario, guiding you through the setup of your acoustic model and the assignment of appropriate absorption, scattering, and transmission properties. 

Whether optimizing an open-space office for a productive work environment or ensuring excellent speech intelligibility in a lecture hall, CadnaR enables you to assess acoustic quality using industry standards and advanced evaluation methods.

Key features of CadnaR include:

  • Cutting-edge calculation methods: particle model, image source model, hybrid model and more. Fast calculation times thanks to innovative technologies such the support of NVIDIA’s CUDA API.
  • Import and input of obstacle objects including barriers, box-type obstacles and polymeshes to allow any kind of complex room shape. Easy definition of the acoustic properties such as absorption, transmission and scattering.
  • Easy import of room geometries via DWG, DXF, SketchUp, IFC and from CadnaR.scan App.
  • Import your speakers in CadnaR, find their optimal position and alignment, calculate reverberation time, signal level, background noise levels and speech transmission index STI to ensure that these messages are intelligible in large public rooms.
  • Automatic calibration of absorption and scattering coefficients to achieve user-defined or measured target reverberation times.
  • Acoustic assessment of open-plan offices based on speech levels and reverberation time according to DIN 18041, ISO 3382-3 and VDI 2569 as well as innovative intelligibility-based approaches such as the STI-Matrix.
  • Extensive possibilities for project organization with the Object Tree and the use of variants. This allows to handle and compare different planning scenarios and therefore allows to find a tailored acoustic concept to improve the situation in your specific project.
  • Calculation of psychoacoustic parameters such reverberation time (T10, T20, T30), Speech Transmission Index (STI) and many more. Cutting edge auralisation techniques, including the effect of several sources at each receiver position.
