Measurings on the graphs

[Se7en]

My I ask what the scalings are in the left side of graph represent.
I am guessing the brainwave scale is DB?
But I am in a loss with Accelerometer.
My X is between -0.2 and -04 which would mean my head is tilted.down slightly.
My Y is between 0 and 0.2 which means it is sometimes slightly left.
Am I correct with that?
My Z is stable at 1? So I am not moving up and down a lot but I am 1? Above baseline 0.???
How can Z be always be 1 and what is the unit?

Hope the question is understandable

Correct it is DB.

For the other values, you can find these detailed in the Tech guide https://musemonitor.com/Technical_Manual.php or by press the "?" for the in app help.

Accelerometer is measured in gravity (g's), so 1, means 1 Earth standard gravity of 9.81m/s2, e.g.
Negative X would be a slight upward tilt.
Positive Y is right roll.
Z will always be 1 unless you're jumping up or down.

You can find a helpful diagram in the Interaxon docs, which are linked from the tech guide: http://android.choosemuse.com/enumcom_1 ... meter.html

Dear James

Sorry to bother you again but there is a discussion in the community weather the scale on the left side of the website graph is.

1. A randonm scale
2. DP (as I understood your answer)
3. PSD as described in the manual

Could you please be so kind and verify?

[James]

It's #2 and #3.

Power Spectral Density in Bels (or dB if you prefer).
