@sokogear Get a dB meter.
Play pink noise through your system at a level to read at about -50 or -60 dB. Use a fixed position for your meter. Turn on the Schumann device.
Read the meter, It should increase by a 1/4 to a 1/2 dB. .
A small change but still significant. Any fractional dB increase is still a lot of energy.
