10Hz-1khz Omnidirectional Spherical Hydrophone for Marine Bioacoustics
1.Working frequency band
The working frequency band of hydrophone is 10Hz-1000Hz.
2.Receive sensitivity
The receiving sensitivity within the working frequency band of the hydrophone should not be lower than -197dB.
3.Horizontal directivity
For the omnidirectional, its measuring frequency points 20Hz, 500Hz, 1000Hz.
horizontal directivity
For greater than 180°, measurement frequency points are 20Hz, 500Hz, and 1000Hz.
4.Resistant to hydrostatic pressure
The hydrophone should be able to withstand the 25Mpa hydrostatic pressure test.
5.Receive sensitivity
The hydrophone number is H222C Ti 01#, and the appearance is as follows.
Receiving sensitivity of hydrophone is shown in the following table.
f/kHz | Mx/dB | f/kHz | Mx/dB |
10 | -195.2 | 125 | -195.3 |
12.5 | -195.3 | 160 | -195.0 |
16 | -195.1 | 200 | -195.2 |
20 | -195.2 | 250 | -195.4 |
25 | -195.3 | 315 | -195.2 |
31.5 | -195.3 | 400 | -195.0 |
40 | -195.1 | 500 | -195.4 |

Horizontal Directivity
Hydrostatic Pressure Test
After the hydrophone passed the 25Mpa/0.5h hydrostatic pressure test, the appearance of the hydrophone was not damaged or abnormal. The insulation resistance between the positive and negative electrodes of the hydrophone was greater than 200 megohms, and the insulation resistance between the positive and negative electrodes and the shield was greater than 200 megohms.
Measurement Results
The hydrophone was tested to meet the technical specifications.
