Abstract：A description is given of the results of COOMET.AUV.W-S1 supplementary comparison of free-field hydrophone calibration in the frequency range 250 Hz to 8 kHz between Hangzhou Applied Acoustics Research Institute – a pilot and Russian National Research Institute for Physicotecnical and Radio Engineering Measurements. Two standard hydrophones of TC 4033 and GI 55 were calibrated in this comparison. Reciprocity and comparison methods, their calibration facilities were used to assess the current state of free-field hydrophone calibration in low frequencies. The results indicate that the sensitivities of two hydrophones calibrated by China and Russia have good consistency.The deviations at most frequncies between the sensitivites and their reference values are less than 0.40 dB,the maximum deviation is 0.59 dB.The results prove that the lowest frequency of free-field hydrophone calibration of China and Russia can be extended to 250 Hz.
