Nor-Build - Building Acoustics Software

Software for building acoustics to allow the 'drag and drop' of measured data from Norsonic analysers to instantly generate test reports.

  • New Linear averaging of multiple speaker positions in accordance with approved document E of the building regulations
  • Implements a wide range of National and International standards; e.g. ISO 140 / 717, ÖNORM, SIA 181, etc. Calculation of spectrum adaption terms C, Ctr and CI Direct calculation of R’w, R’J,w, DnTw, L’nw, L’nTw, etc.
    Field and laboratory measurement protocols supported
  • Air and structure borne insulation and absorption indices calculated
  • Data editing and selective averaging of the stored measurement data
  • Graphical and numerical display of the results
  • Multiple display of the results on the same diagram to aid comparison
  • User friendly presentation of results with direct print out of the standardised report forms
  • Export of the entire project to Excel for user-specific formatting (inserting company logo, changing the layout etc.)
