Having a look at the microphones, we see that there was a first speed increase of +10% at 14:11:00 UTC (from 270 Hz to 300 Hz) when the control was set from "5" to "10."
Then another +10% (from 300 Hz to 330 Hz) at 15:40:00 UTC due to a further speed increase from "10" to "15."
The best witness is ENV_EQB2_MIC
At 13:10 UTC Sc_NI fan speed level has been reverted back to 5 while Sa_NI has been increased to 15, for noise hunting purposes.
