Page: Evaluation
The page <
Evaluation
> visualizes important parameters of the acoustical monitoring as well as of the
environmental condition logging. By applying this graphical evaluation tools you can easily assess the
quality of your recorded data and intervene, if data quality is below your expectations.

The following plots are available:
4.2.4.1
Reference Level
This plot (see Figure 35) visualizes the sound pressure level of the daily reference signal in reference
to the maximum sound pressure level (SPL) of the microphone in dB (see section 4.2.3.2). The
horizontal grey lines mark a ±6 dB discrepancy of the recorded SPL from the SPL determined in the
calibration. Variations of the daily test signal level either indicate an altered microphone sensitivity
(microphone sensitivity can alter due to ageing, weather induced effects or deposed dirt particles on
the microphone´s protective grid) or a changed SPL of the test signal speaker. If the daily test signal
level is also after a restart of the system constantly beyond the ±6 dB lines, the microphone or the
reference signal speaker may be defective. Please contact the support of bat bioacoustictechnology.
To toggle between the reference levels of different microphone channels, use the arrow buttons "<"
and ">" next to the plot.
