Web14 feb. 2024 · While some hydrophones are quieter than others, in general, they are noisier than other types of microphones, especially those designed for quiet environments. To overcome this challenge, hydrophone arrays are often used, which consist of multiple hydrophones that are spaced apart and used in combination to improve the signal-to … Web27 feb. 2024 · Physical effects during transmission are however important: I cannot pass the same signal to high-frequency and low-frequency hydrophones, the latter one will have an unfair detection range. The same screw must be heard much better on 1kHz than on 2k-10kHz bow hydrophone.
