It is inherent to the system.

For electrosensitives, the most damaging frequencies are between 5kHz and 10MHz.

I measured that with a special spectrumanalyzer.
As long as the peaks were in the µV range (microVolt), it was acceptable, but as soon as they were in the mV range (milliVolt), electrosensitives experienced troubles.
