Ocean Sonics

Ocean Sonics is a world-leading developer of passive underwater acoustic monitoring solutions for military, naval and security applications. Designed to be integrated seamlessly into existing defense systems, our products allow operators to measure, process, and analyze underwater sound in real time, supporting mission-critical operations, threat mitigation, and situational awareness.

Our icListen Smart Digital Hydrophone is a proven solution that delivers precise, real-time acoustic intelligence, enabling naval forces, defense contractors, and maritime security teams to detect, classify, and track underwater threats with accuracy and reliability. The innovative Ocean Sonics product portfolio enhances maritime defense capabilities while ensuring operational efficiency and environmental responsibility.

Hydrophones

The icListen range of smart digital hydrophones enables real-time processing, streaming, and recording of acoustic data without the need for additional pre-amps, filters, converters, or datalinks. The compact self-contained units are fully calibrated and offer the ideal combination of performance and sensitivity, providing critical situational awareness for enhanced decision-making during naval and underwater operations.

icListen hydrophones feature ultra-low noise and a wide dynamic range for high-quality data and long-term stability. Multiple units can be synchronized to create a simplified and convenient multi-channel array.

These proven solutions have been integrated with multiple globally-recognized ASV and UUV platforms, and are ideal for a wide range of defense and security applications, including:

• Identification and analysis of potential threats such as enemy vessels, submersible vehicles, and divers
• Creation of acoustic ranges for evaluating the signatures of navy vessels and submarines and ensuring minimal noise emissions
• Locating pingers during search and rescue operations or retrieval of assets such as ROVs & AUVs
• Identifying the presence of marine wildlife during defense exercises

Software

Lucy II

Lucy II is an advanced acoustic processing software package designed for use with arrays of icListen hydrophones. The Windows-based software allows users to locate and set up one or more hydrophones, and stream, record, and analyze data.

The versatile and intuitive software can present data both graphically and numerically, and is optimized for easy reading during complex field operations.

Marco

Marco software is used to locate and check the status of all icListen hydrophones on the network. It can be used on any laptop or PC to launch the built-in web server on icListens or other instruments. The software is included with all icListen purchases.

Talk Assistant

Talk Assistant software program is used to set up our icTalk HF Smart Projector. Users can configure a variety of sound patterns such as clicks, tones and sweeps. The software is included with all icTalk purchases.

PAMGuard Plug-In

The PAMGuard Plug-In allows icListen hydrophones to be used with the industry-standard PAMGuard bioacoustics analysis software.  With this plug-in, icListen units can stream data in real time for detection and measurement of marine mammal sounds during defense exercises.

Deployment Kits

icListen Listening Kit

The icListen Listening Kit provides everything you need to get up and running with deployment of icListen hydrophones for shallow and deep-water recording, providing accurate and reliable acoustic data. The kit includes an icListen hydrophone, a Launch Box, cable, guard, and Lucy II processing software.

Acoustic Buoy Listening Kit

The Acoustic Buoy Listening Kit is a complete solution for easy monitoring of radiated noise and marine mammal noise, ensuring enhanced underwater situational awareness. The kit includes an icListen hydrophone, an acoustic buoy, cable, in-line hydrophone guard, and Lucy II processing software.

Fyrefin Tow Body Kit

The Fyrefin is a tow body that allows users to isolate the hydrophone recording from ambient noise made by the towing vessel, resulting in cleaner and more accurate data. This kit includes an icListen hydrophone, the Fyrefin, a Launch Box, cable and grips, guard, and Lucy II processing software.

Shallow Water Tripod Kit

The Shallow Water Tripod Kit allows easy and convenient deployment of an autonomous hydrophone array, ensuring high-accuracy sound localization, tracking, and detection. Hydrophone separation can be adjusted up to one meter. The kit includes four icListen hydrophones, the tripod, a battery pack, cable and guards, and Lucy II processing software.
