Using the Mezzo Intensity Analyzer Module to analyze data
The “Display” tab contains all the different controls to select the appropriate data to display.
The
buttons allow to view the live data (instantaneous data) and overall average. The
“Live” setting is only available during the measurement. Once the measurement has ended, only
the “Overall” average data is available.
The
buttons allow to select which spectrum type to display from the selected
spectrums in the Data Setup. See section 4.2 Selecting Data Type, p. 11.
The
buttons allow to view the basic data which are Sound Intensity Level, Sound
Pressure Level, and PI index.
When displaying sound intensity levels, the red bars shows positive sign intensity, whereas the
blue bars shows the negative sign intensity.
The
buttons allow to view the advanced field indicators which are P|I| index,
Extraneous Sources, and Time Variability. These indicators are not available in “Live” view because
they need the whole dataset in their determination.
The
buttons allow to add a dBA, dBC or dBZ frequency weight to the spectrum. Note
that global levels in dBA, dBC and dBZ are always shown on the right of the spectrum.
