icListen AF

Designed to collect audio frequency sound data, this signature icListen hydrophone is the industry standard broadband marine acoustics.

Small enough to carry in one hand, our simple, accurate, and reliable smart digital hydrophone allows users to collect, process, and listen to ocean sound data in real-time. When deployed, the icListen can give you information that will help with decision-making that needs to be done in the moment, for example, classifying bubbles and gases, monitoring for earthquakes and tsunamis, and shipping noise. 

It is also powerful enough to be combined into simple or complex digital hydrophone arrays. As the most reliable and user-friendly hydrophone available, understanding ocean sound has never been easier. 

Have a member of our sales team help you put together a full ocean listening package for your project, complete with a Launch Box, cables, and software!

All of our hydrophones come with complimentary training.

Lucy Software

Lucy is a PC program developed to allow users to visualize and interact with data collected by the icListen Smart Hydrophone. Lucy displays real-time waterfall and time-series data. Lucy's waterfall display allows users make accurate measurements from recorded and/or live data.

“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.”

Tom Dakin Sensor and Technology Business Development Officer and Resident Ocean Acoustician Ocean Networks Canada

“We have been working with Ocean Sonics in our technology demonstration program since the first prototypes. Our science users have been very impressed with the very high quality data sets. Ocean Networks Canada is expanding our hydrophone network with Ocean Sonic icListen HF smart hydrophones across our observatory including new sites across coastal BC, as part of the Smart Oceans™ program. The compact size, Ethernet interface, high reliability and exceptional performance make these systems ideal for ocean observing applications such as mammal classification, vessel and ambient noise studies.”

Scott McLean Director(Former) Ocean Networks Canada

“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.”

 

Ross Chapman Professor Emeritus University of Victoria

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.
