Mind Monitor

Hi All,

I started using Muse and Mind Monitor yesterday. I noticed there's a noticeable spike at 60 Hz that hardly moves. Could this relate to the North American AC power supply? There are also smaller persistent spikes just below 24 Hz and above 40 Hz. Does this indicate a fault in the hardware?

Just noticed that spike at 60 Hz is there even when I'm not wearing the muse. In that situation there are also several other persistent spikes but not the other two I mentioned. Can someone explain what the Muse is detecting when it's not being worn?

A spike at 50hz or 60hz is power line noise. Which frequency you see will depend on your region.
