Displayed in the Logger Noise Table are all values that are needed for an evaluation.

3.3.1 Table Fields
The Leak Score is specified in a range from 0 to 100. The higher
the number, the greater the probability that measurements will
actually detect a leak.
The goal of the noise measurement with Loggers is to obtain as
reliable a statement as possible regarding the presence of a leak
at a specific point of the monitored water network. For the greatest
reliability with respect to the presence of even small leaks, all
information that is indicative of a leak near a Logger should be
included. Misinterpretations should be avoided in this process.
The measurement values obtained from the histogram (see 3.2.4
Correlation Context Menu) – particularly the lowest ascertained
sound-level value dBmin – which are a strong general indicator of
a leak, are included in the subsequent processing.
In addition to the described histogram evaluation, the Leak Score
includes, above all, knowledge from the frequency response
