I want to make sure I’m describing the headband’s readings as accurately a possible in the applications i’m working on. The documentation says the readings are
log band power (dB)
but i’m confused by exactly what that means (i suppose it might just be by the word “log”.) I’ve been reading that different waves generally have certain amplitudes, but the readings we are given all seem to be standardized somehow, fluctuating in the same range. Anyone know the exact origin of these numbers? I feel like i’m skewing something if i simply say, for example, “xx dB of alpha-band activity,” because that’s probably not the exact amplitude going on in the brain at that moment. Any insights?
