Weird noise peaks at 16 Hz and 24 Hz

Hi,

I have been receiving weird peaks from my Ganglion lately. It started when I moved to a new building. I'm getting noise peaks at 16 Hz and 34 Hz, see picture. Has anyone else experienced the same? I guess it has something the do with the lighting, but at the same time, I thought this only affected the 50 Hz?

    Can you try moving to another room, using other lighting, etc.? Electronic devices emit various EMF ElectroMagnetic Field radiations. For example LED and CFL lighting contains power supplies that oscillate at different frequencies, and could cause harmonics or sub-harmonics at EEG frequencies. Regardless of which EEG amplifier you use, it is susceptible to such interference.

    Ah, that makes sense! I must have been that since after moving to a room with different lights, I don't have the problem anymore.

    Thanks, @wjcroft
