"Way back when"   I calibrated my hydophone at Black Mohican Cal Station 
in PA, I was happy to get it within 1 dB.  The readings are usually done to 0.1
dB, but the reliability and reapeatability of all setups and instruments is 
such that 1 dB is the pro forma standard.  You can demand anything you want, 
but it will cost you $$$ and time.  Usually, +- 1 dB will not start any 
arguments.
