QUALIFIER – Sound Testing

Having made airborne, façade, impact or reverberation time measurements with the B&K 2260D running the BZ7204 building acoustics module, 7830 Qualifier software is used to post-process and document the 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.
