Congratulations on your purchase of an icListen Smart Hydrophone.
Ocean Sonics is dedicated to your success. We want to ensure you
collect the best data possible and that you get everything out of
your data that you need. This user guide will help you navigate how
to most eectively use your hydrophone, from basic set up and
conguration through complex deployments.
Ocean Sonics recommends that you review the entire user guide
before you begin using your hydrophone. If you have any questions
that are not answered in this document, please do not hesitate to
contact us for clarication.
With the purchase of every hydrophone, Ocean Sonics oers an
Introduction to icListen training course. This is an hour long session
with an Ocean Sonics team member that will get you comfortable
using your icListen Hydrophone and help fast track your ocean
sound data collection projects.
Many of the deployments featured in this guide use additional
Ocean Sonics tools and accessories. If you are interested in
purchasing these tools, or if you would like to know if they are useful
for your data collection needs, contact our technical sales team.

icListen User Guide
1v2021.1
Introduction
The icListen Smart Hydrophone combines high signal integrity, data storage capacity, low
power, and small size with the ability to process sound data in real time. This guide provides
comprehensive information on how to congure and use your hydrophone in the eld as well as
its maintenance and care. It also links directly to many other relevant documents on our website
(these will either open or download based on your browser settings). All referenced documents
are also provided on the thumb drive provided with your hydrophone.
The icListen is an ethernet based device. This allows the hydrophone to connect to networks,
stream data, and be easily integrated into multi-device platforms. The icListen can be used
as a fully autonomous device providing 256GB of storage and real-time streaming of both
waveform and spectral data. The hydrophone will operate for up to 8 hours using the internal
rechargeable battery. Optional battery packs can also be used to extend deployment time.
The amount of recording time available is dependent upon the sample rate as shown below.
SampleRate
(kS/sec)
24 Bit Data
GB per day Days with 256 GB
16 4.5 56
32 8.6 29
64 16.9 15
128 33.5 7.5
256 66.7 3.8
512 133.1 1.9
Note that the storage time can be increased signicantly by enabling Duty Cycle Logging to
record data periodically, or by storing only processed FFT data. Waveform data is logged in the
standard “.wav” format, making it accessible from a wide range of software programs.
Spectral analysis of data can be performed by the icListen and can be averaged for up
to one minute to reduce data volume. The data is provided in .txt format, suitable for
spreadsheet viewing and further analysis. Full details are available in the icListen Log File
Formats document.

Ocean Sonics provides a Microsoft Windows application, Lucy, which can be used to congure
the icListen (it performs all the functions of the web interface described in this User Guide) and
provides additional sound recording and data analysis capabilities. Lucy can stream real-time
audio and spectral data, provide real-time sound analysis and record icListen data to a computer.
Replay functions are available to review recorded spectral FFT les and waveform data.
Each icListen comes with a 30-day trial of the Lucy application. For full details on how to
install and use Lucy please see the Lucy Software User Guide.

Compatibility
This User Guide (V2021.1) applies to all models of the icListen hydrophone running version 39.0
rmware. To determine your current rmware version go to the ABOUT page in the hydrophone
web interface ( See “About Page” on page 13).
If you are running an older version of the rmware it is highly recommended that you update it.
Instructions for doing so are in “Firmware” on page 37.
This release of icListen rmware is compatible with Lucy v4.3.8 and up, and Marco 2.0 and up. It
is also compatible with most third party FTP/SFTP/SCP clients, SSH clients, and web browsers.
The web interface requires javascript to be enabled in your browser for full functionality. Logged
waveform (WAV) data can also be viewed/edited by audio editing software capable of dealing
with uncompressed PCM WAV les.
Here are some free third party programs recommended by Ocean Sonics for use with your
icListen:
Audacity
Free open source audio recording and editing software.
FileZilla
Free open source FTP client.
PuTTY
Free SSH client.
