icListen SJ9
icListen Smart Hydrophones are the world’s first digital hydrophone. Use the icListen for real-time listening and event detection, or as an acoustic recorder.
The flagship and finest high-frequency icListen SJ9 is recognized as the standard in broadband digital marine acoustics. Designed and created in-house, the SJ9 is equipped with Ocean Sonics’ ALTA yellow sensor. Along with a depth rating of 900m, the SJ9 offers high-frequency broadband, and high-quality data. The SJ9 has a frequency range 10 HZ to 200 kHz. Use the SJ9 to stream data, log data, or both all in real-time.
This high-frequency icListen can monitor sounds from pile driving, ocean observation, and energy related projects.
With self-synchronization, GPS sync, and Network Sync, the RB9 can easily be deployed in hydrophone arrays or create wide area arrays. It also has easy configurations for battery and memory economy for short-term or long-term deployments.
icListen internal processing capabilities saves you time and provides you with the most accurate data possible, without the need for onerous gain settings. The icListen is small enough to carry in one hand, allowing you to deploy with smaller craft, or deploy on autonomous vessels. 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.

“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.
