“…At the same time, the noise-signaling situation corresponded to an inequality of the form U s /U i ≥15 dB, where U s -electric voltage on the useful signal recorder, U i -electric voltage of the interference. The implementation of the cases of operation of the source in a certain mode corresponded to the ideology of works [10,14] in terms of the formation of spatial selectivity with appropriate matching of the resistances of the generator and electromechanical converter [15].…”

“…Research and development of hydrophones have grown rapidly in the 20 th century and is still increasingly studies field [1]. The hydrophone application ranges from geophysics-volcanologic monitoring to underwater military applications such as submarine location, and civilian uses such as monitoring sea animals [1]. A forefront research field relies on the development of ultrathin hydrophone arrays.…”

“…Nonetheless, almost 71 % of the earth's surface is covered with water and the need of seismic monitoring to retrieve key information on tectonic movements is not limited to the mainland. Therefore, high performance underwater acoustic detection equipment is urgently required to provide widespread monitoring systems, in which hydrophones are considered as one of the core components [1]. In example, in Southern Italy, west of the city of Napoli is located the Campi Flegrei caldera that continuously exhibits an intense activity and extends from the land to the sea.…”

“…However, the actual density of the ambient water is usually flexible, making the zero-buoyancy condition not easy to meet, especially in the sea application. Therefore, it is necessary to suspend the vector hydrophone onto the mooring rope of the array for a position-fixed vibration [ 31 ]. In general, the suspension is flexible to avoid interfering with the signal pick-up as much as possible, which is also conducive to suppressing the vibration from the attached mooring rope.…”

“…For a well-designed suspension system, it should have the ability to isolate the vibration from the attached mooring rope, so as to suppress the mechanical noise [ 31 ]. Although traditional OSSS can meet the demand of many applications, its ability of mechanical noise suppression is not enough when faced with the increasing demand of the weak signal detection [ 39 , 40 , 41 ].…”
