Chris,

Noise figures are meaningless if not compared to a common input - in 
this case a common sound source. The missing data is the mic output in 
mV/Pa (milliVolts per Pascal sound pressure).

We can't do this outside of a lab, so we can only compare the noise 
measurement with the recordings of the sound source.
