7830 Qualifier

Building Acoustics Software - part of the 2260D-001 and 2260D-002 Systems*
Having made airborne, façade, impact or reverberation time measurements with 2260D Investigator running the BZ7204 building acoustics module, use 7830 Qualifier software running on a PC to post-process and document your results.
Using Qualifier's spreadsheet-like data sheets, it is possible to manually adjust data used in calculations, for example, to change levels or reverberation times. The results can be observed immediately.
Reverberation-time measurements may be averaged in two ways: either averaging of reverberation times (T20 and T30) or averaging of decay curves (multispectra), also called ensemble averaging.
This mode has the advantage of producing an average decay curve (multispectrum) for each frequency band
Extensive documentation facilities are available. These allow items such as SRI graphs and text to be entered into a report and sent to the printer. Graphs can also be exported via the clipboard.
