20Hz~15KHz Vibration-isolated Hydrophone for Underwater Communications

20Hz~15KHz Vibration-isolated Hydrophone for Underwater Communications

This vibration-isolated hydrophone features a composite structure—comprising unique polyurethane elastic arms and a high-strength non-metallic flange—that functions as an efficient, wide-band vibration isolation system. The design actively isolates and significantly attenuates structural noise and vibrations transmitted from the mounting base, thereby enhancing the acoustic signal-to-noise ratio. This ensures the capture of pristine underwater acoustic signals even in environments characterized by complex vibrations, while simultaneously protecting the core sensitive components from mechanical shock.
