flyback: unless its over an ohm, the esr is prob going to be pretty hard to test
and i wouldnt even try without a DSO
i would put it on scan or roll mode with 1sec divs, measure the cap voltage open, then switch like 10 ohms across the cap
then see where the voltage drops out to instantly before normal discharge rate
esr is initial voltage and ref resistance and some math
and yeah id prob have to do it again and set to a faster speed and then do some sex with the trigger

8-10mv is noise floor
reza: look at the sensitivity spec for some electrets
1 pascal is 94dB SPL
but yeah its prob going to be between like 5 and 50mV
sound pressure level
normal listening levels are like 60-90dB SPL
