Diagram
Each bar represents a single noise recording.
X-axis ... course of measurement over time
Y-axis ... noise level in dB
The colour of the bar shows the approximate frequency of the noise.

The point where the two green lines intersect marks the quietest recording in
the displayed measurement, the so-called “leak value”.
Leak value (lowest value to be displayed)
The leak value refers to the quietest recording in the displayed measuring
period. The values of this recording are shown in the three fields directly
under the diagram:
Left-hand field … ESA value of the recording
Centre field … Noise level in dB for the quietest measurement
Right-hand field … Frequency of the noise in Hz
