This view uses a split display with a spectrum L(f) on top of a numerical table.
The active panel (chart) is of blue color while the other panel is grey. Tap on a panel to activate it.
There is a header line showing the selected standard, if available the source position and a possible warning message.
The function name is supplemented with the corresponding colour and the selected frequency band.
L2: average sound pressure level in the receiving room.
L2': average sound pressure level in the receiving room corrected for background noise.
Lb: average sound level pressure level of the background noise in the receiving room.
Corr: applied correction values according to the standard.
You are now looking at different averaged level spectrum used for background noise corrections.
If the rating is based on rating results of the individual source positions (e.g. ISO 16283) then no total background corrections are available, only the individual ones.
Use the soft button to switch the source position.
Tap and drag vertically on the graph to change the visible range.
Press and hold anywhere on the graph to bring up the context menu or press the large ü button
Zoom (X-axis): X-axis zoom function
Range (Y-axis): Modifies the dB scale
Auto Range: Autscaling Y-Axis
The table presents the numerical values from the spectrum graph above.
Each line consists of the frequency band (Frequency), level average(s) (L1, L2') and the reverberation times (T).
If the rating is based on rating results of the individual source positions (e.g. ISO 16283) then no total background corrections are available, only the individual ones.
Use the soft button to switch the source position.

Tap to toggle between the different data types (Reverberation, Receiving, Source, Background and Rating).
Tap to toggle between source positions (#A...#D).
The displayed results are based on the corresponding source position data.
Press to toggle between spectrum and tabular view.
Note: It not only turns a graph into a table but it also changes the dual type frame into a single type (and vice versa).
