This step is performed as the initial preparation before starting experimental measurements in the field. The process of normalization was carried out on the device sound audio processing, and hydrophones as front end sensors. Normalization is conducted in frequency domain, and shows that the comparison of sensitivity was fluctuate at different frequencies. Overall, have obtained results that sensitivity ration among hydrophones are:  H-123 has a sensitivity ratio of 0.85 compare to sensitivity of H-2, and has a sensitivity ratio of 1.5 compared to the H-ref. While H-2 has sensitivity ratio of 2.3 compare to H-ref. From these results, we hope to contribute in the research topics based on measurements. So that the problems in the sensitivity of measuring devices that are not uniform can be solved.</p><p> </p> ER -
