Software CIS and CMA CESVA adapted to the new ISO 16283-1 and ISO 12999-1 standards

CESVA has adapted its programs CESVA insulation Studio (CIS) and CESVA Measuring Assistant (CMA) to the new ISO 16283-1: 2014 and ISO 12999-1: 2014 standards.    

  • ISO 16283-1: 2014. Acoustics. In situ measurements of sound insulation in buildings and building elements. Part 1: Airborne sound insulation.
  • ISO 12999-1: 2014. Acoustics. Determination and application of measurement uncertainties in building acoustics. Part 1: Sound insulation.

The 6.9 version of the CIS incorporates the ISO 16283-1 standards in its entirety:

  • Procedures by default and low frequency 
  • Methods of fixed positions of the microphone and manual scanning and machining of microphone
  •  Evaluation of the stability of the measurements for detection of self-generated noise   
 It also allows calculating the uncertainty of the global indices from the uncertainties of the isolates by third octave bands under the assumption of complete positive correlation of these and moving the reference curve in steps of 0.1 dB. 

  Version 4.4 of CMA has been adapted to the default procedure and the method of fixed positions and incorporated the evaluation of measurement stability in the receiving room and updated checking continuity of the spectrum (level differences between bands lower than 8 dB). It has also reduced the time spent searching for devices.  

Currently, the measurements according to this new standard are already mandatory in some regions and in some municipalities comprising as the measurement standard the ISO 140-4 standard or any other standard that replaces it.

The new ISO 16283-1 standard differs from ISO 140-4 both measurement protocol and the calculation method of isolation frequencies.

 These updates are completely free and are available for download on the website of CESVA:  

Shortly CESVA will incorporate into its training, specific workshops about the measurement of airborne sound insulation under the new ISO 16283-1 standard with his solution Global Insulation Package (GIP).
