Now,
when in the north of Europe and the USA
starts cold snaps, and temperatures fall
to + 5-0 degrees Celsius, we can have some
difficulties with obtaining acoustic data ... If everything is good in
bees' families, then the signals are usually weak ... In order to see the
picture of the signals in Monitoring mode in principal, you should raise the
gain to yellow or even red (warning) zone.
As a rule, if everything is good in families, then not only the signal
level is low, but the signals themselves are poorly differentiated ... There
are no jobs in the hive that can attract a large number of workers. And at such
moments, the reliability of the diagnosis is not high. Most importantly, that
in the Monitoring mode, it can be seen, that the bees are alive and calm. In
the General State Control mode, it is also seen that the levels of the bars on
diagram are low and poorly differentiated. In
Brood Control mode, the chart can fluctuate around zero and can be
colored in half in red and white, since the average value of this chart is zero
.... This chart doesn’t show either the presence, or absence of open brood ... It
talks about weak acoustic signals in the hive, and that the state of the bees,
in general, is normal ....
