July 13 and 15 in Saint Petersburg TV filming of the two world-class opera singers –
Rene Flaming and Dmitri Chvorostovski in St. Petersburg palaces was conducted. Performance
was organized in two parts, with twice repetitions of the same program, which was conducted by
the organization of filming. July 13 filming was performed in the Ball Hall of the Great Peterhof
Palace and only technical personnel and organizers of the event were presented. It was raining all
the time. July 15 filming was performed in Usupovski Palace and public was invited to the
performance. By the end off the concert started a strong thunderstorm. In both cases singers were
accompanied by symphony orchestra with conductor Konstantin Orbeljan.
We were lucky to be invited to both events and make registration of the signal with “EcoTester”
instrument. Recording was done in automatic mode with 5 second interval. July 13
EPC/GDV instrument running on 12 V battery with air antenna and personal computer, and July
15 stand-alone “Eco-Tester” was used.

Results
Fig.1 presents time dynamics of Area and Intensity recorded July 13. Shaded areas at the
graphs mark the moments of singers’ performance. We pay attention to two moments: strong
descending trend of the area graph and big difference between scales of data (difference between
maximum and minimum values at the given interval) at the moments of performance and
moments of intermission. The advantage of this performance was in big intermissions necessary
for filming which allowed calculating statistical difference of data recorded during performance
and intermission.
