icListen Smart Hydrophones

 

 

 

Flexible enough for you to use as an acoustic recorder, digital hydrophone, real-time acoustic event detector, or all three at once.

Small enough to carry in one hand, allowing you to deploy with smaller craft, or deploy on autonomous vessels.

Powerful enough to be combined into simple or complex digital hydrophone arrays.

 

 

 

 

 


 

Types of IcListens

icListen HF

HF3500mVertical

 

The flagship icListen HF is becoming recognized as the new standard in broadband digital marine acoustics. Use it to stream data, log data, or both.

High Frequency Applications

  • Environmental Monitoring
  • Ambient Noise Measurement
  • Marine Renewable Energy
  • Pipeline Leak Detection
  • Ocean Observatories
  • Marine Mammal Monitoring
  • Ocean Noise Measurement

 

 

 

 

icListen HF with Reson Sensors

The 900m depth rated broadband Smart Hydrophone is based on the TC4059 sensor. Frequency range is 10 Hz to 204 kHz with the upper limit software selectable. This product gives Reson users the performance they expect, integrated with the industry leading icListen Smart Hydrophone. The RB9 includes all the signal processing, event detection, large memory recorder and streaming features found in the icListen HF family of products.

High Frequency Applications

  • Environmental Monitoring
  • Ambient Noise Measurement
  • Marine Renewable Energy
  • Pipeline Leak Detection
  • Ocean Observatories
  • Marine Mammal Monitoring
  • Ocean Noise Measurement

 

 

 

 

icListen HF-X2 

The X2 offers all the same features of the standard icListen HF but with its reduced analog input gain, it records peak sound levels greater than 210 dB re.uPa without clipping or saturating. 
Use the Event Detection feature to ensure loud events are recorded or send an event message when a preset sound level is exceeded.

High Frequency X2 Applications (High Intensity Option)

  • Pile Driving
  • Dredging
  • Construction Noise
  • Explosions

 

 

icListen AF(L)

 

The AF(L) comes with all the features of the icListen HF, including spectral processing, event detection, PPS synchronization, and the powerful Web Server available on the Ethernet interface Play deep-ocean sounds from icListen AF through your PC speakers using the Lucy software, in real-time.

Like the icListen HF, the new AF(L) is compatible with many radio systems, including GSM, ISM and satellite.

Audio Frequency Applications

  • Marine Mammal Monitoring
  • Earthquake & Tsunami Monitoring
  • Shipping Noise Measurement
  • Ocean Observatories

Testimonial
"Ocean Networks Canada performed a wide range of tests on the hydrophones prior to deployment to verify the manufacturer's specifications. The hydrophone instruments met all the manufacturer's specifications and were easy to use. Both models satisfy our requirements for dynamic range, sensitivity and, most importantly, reliability. When coupled with the fast and friendly customer support we have received, these LF and HF hydrophones are a good choice for our ocean observatory."

Testimonial
"I have used many different hydrophones on different systems, but these icListen hydrophones are the best I've seen in many years. They're calibrated to very low frequencies where I've never been able to get reliable data."

Testimonial
“The Ocean Observatories Initiative (OOI) Regional Scaled Nodes (RSN) had requirements for very broadband hydrophones with good noise floor characteristics and a wide dynamic range. The icListen HF hydrophones satisfied these requirements at a reasonable cost. The hydrophones were quite easy to use out of the box, and easily passed our intensive First Article tests centered on assuring any instrument will not interfere with or corrode any other instrument. Customer support has been quite good, with very detailed questions answered quickly and accurately.”
