In the context of increasingly complex underwater combat operations and maritime security challenges, the need for real-time monitoring, situational awareness, and accurate data processing has become critical. The icListen digital smart hydrophone offers a comprehensive, modern technology-integrated solution that effectively supports naval forces, maritime authorities, and search and rescue (SAR) units.
Reecotech specializes in providing marine, meteorological, environmental, and defense technology solutions, committed to meeting international standards while adapting to actual operational conditions in Vietnam.
The icListen hydrophone is designed to capture, analyze, and process underwater acoustic signals, enabling real-time detection, classification, and localization of targets. Featuring high sensitivity, wide dynamic range, ultra-low self-noise (32 dB re uPa²/Hz), and IEEE-standard calibration, icListen delivers outstanding accuracy and reliability.
Its self-synchronization capability, ease of configuration into acoustic arrays, and commercial off-the-shelf (COTS) readiness allow icListen to flexibly meet various operational requirements.
Application in Real-Time Situational Awareness
Real-time situational awareness plays a crucial role in monitoring, protecting maritime zones, and responding to underwater threats.
icListen enables detection and tracking of signals from submersibles, vessels, divers, and even seismic signals (earthquakes, tsunamis). It also supports the detection of marine life in training areas, minimizing environmental impacts.
With an ultra-low self-noise level (32 dB re uPa²/Hz), icListen ensures the ability to capture weak signals, supporting timely and precise decision-making.

Application in Acoustic Ranges
Acoustic ranges are used to evaluate the acoustic signature of surface ships and submarines, helping to reduce emitted noise and improve stealth capabilities.
icListen facilitates the deployment of mobile acoustic ranges, thanks to its ability to self-synchronize multiple units without complex external clock systems. The device supports broadband and narrowband analysis and features automated reporting capabilities, minimizing manpower and data processing time.
Application in Search and Rescue (SAR) — Pinger Localization
In emergency situations such as aircraft crashes or lost underwater equipment, fast and accurate pinger localization is critical.
Operating across a frequency range from 1 Hz to 200 kHz, icListen is well-suited to detect standard pinger signals. It can be easily deployed from unmanned vehicles (AUVs, ASVs, ROVs), large and small vessels, or carried by divers.
With operational depths of up to 6,000 meters, a robust titanium housing, and high mobility, icListen is an ideal choice for global SAR missions.
