Analysis of information sources in references of the Wikipedia article "Orders of magnitude (voltage)" in English language version.
-10 dBV Standard voltage reference level for consumer and some pro audio use
The amplitudes of the scalp EEG are markedly reduced and lie between 10 and 100 μV
about 0.7V for all normal diodes which are made from silicon
Most good supplies should offer noise and ripple figures of better than 10 mV rms and for switching supplies figures of 50mV or less should be achievable
