NorBuild - Version Nor1028 -Sound Insulation Calculation Software

• Allows the quantification of the acoustic performance of structures according to a wide range of international, European and national standards, i.e. ISO 717, EN 20717, BS 5821, ASTM, SIA 181 etc.
• Version 4 includes the test procedure and calculation for the new ISO 16283 standard that replace the ISO 140.
• Input data can be taken directly from the  Nor140 Sound Analyser (Nor110, Nor118, Nor121, Nor840 or Nor843 analysers), from file or input by hand.
• Automatic calculation of the rating parameters (DnTw, Rw, LnT,w, etc.) as set out in the standards with the report generator producing the information in the required format.
• Freely selectable frequency range for the display and calculation of the rating parameters.
• Input of all the necessary project data is made via user friendly input screens.
• Graphic and numeric presentation of the results.
• To comply with their own company style, users may redefine the presentation of the reports.
• Energy and arithmetic averaging of the data is performed as required.
• Excel reporter for making customized reports in your local language.

• Interface with the Nor118, Nor140, and Nor843 analysers to fully control the procedure for normal level and reverberation time measurements as well as SweptSine technique.
• Support Nor520 Bluetooth Transceiver for wireless communication for Nor118 or Nor140 measuring instruments.
• Controls up to two Nor265 Oscillating Microphone Booms in a system.
• The user defines the measurement requirements and the associated instrument is then fully set up and the complete procedure controlled by simple mouse clicks.
• On-line display of the measured spectra and reverberation time data.
• Automatically transfers the measurement results to the NorBuild program to calculate the rating para-meters, thus allowing the two modules to be fully integrated.
• The complete data set, measurement protocol and the calculated results are stored together in a project file.

Simple mouse clicks within a Windows interface are used to select the parameters that are required for the measurement. The instrumentation can be configured for one of the four measurement modes Level, Reverberation, Background or Impact. All that is required then is to set the measurement parameters and define the channel allocation. The frequency range can be selected within the limits of 50 Hz to 10 kHz. The choice between parallel (white and pink noise) and sequential (1/3 octave) excitation allows the best compromise between speed and signal to noise ratio to be obtained. The measurement channels can be activated and allocated to source or receiving room for identification by the post-processing program NorBuild.

Once the instrumentation is correctly configured the spectrum of the actual sound pressure level will be displayed on the screen. A simple mouse click will then start the measurement process.
