The ocean is a large, uncharted realm that uses sound as its primary communication and detection system. Underwater acoustics offer essential data about environmental conditions, security threats, and infrastructure integrity.

Enhancing Environmental and Marine Conservation

RESON TC 4014 - hydrophoneHydrophones​​ are essential tools for studying underwater noise and its effects on marine life​. To monitor sound emissions from shipping vessels, offshore wind farms, industrial operations, regulatory bodies and scientific researchers place hydrophones in positions to maintain adherence to environmental regulations.

Hydrophones​ facilitate real-time noise monitoring from pile-driving activities to offshore wind farm construction, enabling noise mitigation tactics like bubble curtains and other designs. Hydrophones are vital for researchers studying marine mammal communication ​patterns and behavioral responses. Scientists study species interactions and habitat modifications through the analysis of whale vocalizations  along with dolphin echolocation clicks and fish noise. Research with hydrophones also shows electric-powered ships produce less underwater noise than traditional ships, to further assist with sustainable marine transportation and mammal policies .

Supporting Offshore Energy and Infrastructure Integrity

Along with oil and gas exploration​, offshore wind farm growth requires strong acoustic monitoring methods to safeguard marine life and essential infrastructure. Hydrophones​ generate highly accurate acoustic measurements that support regulatory compliance while enhancing operational safety and environmental risk detection.

RESON TC 4040 - hydrophoneHydrophones enable oil and gas companies to track subsea infrastructure performance and identify pipeline leaks and structural problems before they develop into serious issues. Operators who analyze subtle acoustic signature changes can execute timely maintenance to minimize environmental risks and operational interruptions.

Hydrophones also assist energy companies in offshore wind operations in monitoring marine mammal activity near construction sites and enabling proactive protective measures.

Advancing Maritime Security and Defense Applications

The evolution of global maritime risks drives national defense organizations and commercial entities to depend more on sophisticated acoustic monitoring systems for detecting threats early and maintaining situational awareness.

Hydrophones deliver precise underwater acoustic information that enables support functions:


  • Passive surveillance of vessel noise signatures

  • Detection of unauthorized underwater activity, like sabotage on critical subsea infrastructure.

  • Security monitoring around ports, naval bases, and offshore facilities

 

The Teledyne RESON hydrophones demonstrate exceptional sensitivity and durability, making them ideal for long-term use in defense and maritime security networks.

Driving Scientific Research and Climate Studies

RESON TC4059 - hydrophoneScientists who study oceanography​ and climate research use hydrophones as essential instruments for extended environmental monitoring. The hydrophones positioned in global ocean observatories track underwater earthquakes, tsunamis, and marine landslides and enable scientists to study changes in geology and climate.

These instruments help marine biodiversity research by recording and analyzing soundscapes in distant ocean areas. Through acoustic environmental research, scientists evaluate ecosystem conditions, track climate change effects, and monitor ocean noise pollution to enhance worldwide conservation methods.

Innovating for Commercial and Industrial Applications

In commercial fishing operations, hydrophones​ serve essential functions in underwater construction projects, and aquaculture systems. Hydrophones enable fisheries to monitor fish populations and improve harvesting methods while acoustic sensors in underwater construction guarantee accurate positioning and structural integrity checks. Hydrophones also allow aquaculture farmers to assess environmental conditions to maintain efficient and sustainable production systems.
