Abstract Using B&K 8104 and TC 4033 as standard hydrophones,an underwater acoustics sound pressure calibration comparison in the frequency range 250Hz to 200kHz was carried out between HAARI of China and VNIIFTRI of Russia from September, 2009 to June, 2010. Although the different measurement methods,calibration techniques and measurement facilities were used,the calibration results from both sides were very close,and the maximum deviation was only 0.36 dB. After the discussing and analyzing by the experts from China and Russia,the consensus conclusion was gotten that the measurement methods and calibration techniques using in the comparison calibration are correct,and the results from measurement facilities are accurate and reliable.
