Yes, depends on the range of the signal.  It will be ~ -144dBFS if the
input signal is full range 0dB.  It will be considerably less if the
signal is less.  Although ears might have a dynamic range of over
120dB, they have considerably less dynamic depth (only 30dB or so in a
critical band, not sure of the full-band figure).

Mosquitos are *considerably* louder than what we're talking about!
