CadnaR 2019.1

CadnaR is a room‑acoustics modeling and indoor noise prediction tool used to design, assess, and optimize the acoustic performance of enclosed spaces. It allows you to build 3D room geometries, assign material properties, define sound sources, and evaluate frequency‑dependent sound pressure levels, reverberation time, and speech intelligibility. Results are presented as visual maps and concise reports to support treatment choices and compliance assessments in classrooms, open‑plan offices, factories, healthcare facilities, and auditoriums.

Key capabilities:

• 3D modeling of rooms with configurable materials and acoustic treatments
• Octave/third‑octave band calculations for sound pressure levels and reverberation
• Estimation of speech intelligibility and background noise conditions
• Scenario comparisons to optimize layouts and material selections
• Exportable graphics and reports for documentation and stakeholder communication

CadnaR is developed by Datakustik. The most popular versions of this product among our users are: 2.0, 2.1, 2.2, 2.4 and 2019.1. The name of the program executable file is CADNA_R_32.exe.
