Ah yes.  Microphone manufacturers sometimes rate sensitivity as dBV/Pa, and=

sometimes as mV/Pa.  A dBV is dB relative to one Volt.  So 1 Volt is 0 dBV,=

0.1 Volt (100 mV) is -20 dBV, and 0.01 Volt (10 mV) is -40 dBV.  So -40
dBV/Pa is the same as 10 mV/Pa.

Just to confuse things a little more, you will ocassionally find that
microphone manufacturers use a reference level of 1 microbar (1 uBar), whic=
h
is 74 dB SPL.
