A Rating Level is a single value for evaluating the potential nuisance factor of noise. It takes into account time of day, nature of the noise (impulsive, pure tones present) as well as the overall levels of the noise.
Uses
Calculation of rating levels according to national and international standards
Noise profile measurement
Industrial noise
Residential noise
Road and rail traffic noise
Evaluation of noise in the environment against noise limits according to national and international standards

B&K 7830 : Qualifier Software
£ 4 a day *
Building Acoustics Software - Windows® based software.
Having made airborne, impact or reverberation time measurements with a 2250 Building Acoustics Analyser or a 2260D Analyser, use the 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 (multi spectra), also called ensemble averaging.
This mode has the advantage of producing an average decay curve (multi spectrum) 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.
B&K have a FAQ - frequently asked question page relating to the 7830 Qualifier software on their web site.
