Giving our oceans a voice
icListen Smart Hydrophones:
icListen is the most reliable, intelligent and user-friendly hydrophone available. Understanding ocean sound has never been easier.
The icListen Smart Hydrophone is used around the world as the standard for acoustic monitoring, streaming and hydrophone arrays. Understanding ocean sounds has never been easier with icListen and our data analysis services. Our users have even said the icListen Smart Hydrophone is fun to use. Trust icListen to give you accurate, reliable, high-quality data.
icListen SJ9
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.
icListen RB9
Ocean Sonics' most popular hydrophone. With a 900 m depth rating, a Reson sensor tip, and a wide dynamic range, the RB9 can easily stream and record high resolution acoustic data for many applications in the field.
icListen SA9
The icListen SA9 models are designed for audio and low-frequency sound data collection. The SA9 hydrophone has a 900 m depth rating and will stream and record high resolution acoustic data in real-time.

“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.
