effect of mic sensitivity

["oryoki2000" oryoki2000]

I'd appreciate it if someone could help improve my understanding of
mic sensitivity and its effect on the loudness of a recording.

Let's say the sensitivity of Mic A is rated at 30 mV/Pa, and mic B is
rated at 15 mV/Pa.  I think this means that the voltage Mic A sends to
the recorder will be twice as high as the voltage Mic B sends when
exposed to the same reference sound.

Now think of using Mic A and Mic B with the same recorder, using the
same settings.  Will the recording of a reference sound made with Mic
A appear to the listener to be twice as loud as the recording of the
same reference sound made with Mic B?

Or, since human hearing responds in a more logarithmic way to
increases in sound pressure, will the recording made with Mic A appear
to the listener to be only slightly louder than the recording made
with Mic B?

Thanks.
