I've tried working this relationship out before, tho I'm not sure
with how much success:

Using an ME66/K6 as a reference in a 60dB SPL soundfield, you would
need to boost the NTG-1 by 10.5dB and the AT897 by 14.9dB to match
the recording level of the ME66. If I'm getting this right the
effective noise floors of the NTG-1 and AT897 are respectively
Message: 18.
Subject: 5dB  and  21.9dB higher than the ME66 at the same dBFS recording
level.
