APPLICATIONS: Overview (click on images for further details)


DolphinEar (DE200 and DE PRO series) have been used by tour boat operators for 15 years. Vessel sizes range from kayaks, RIBs, small and large boats of all descriptions. It gives tour operators an edge in competitive markets. Often whales and dolphins can be heard when they are not visible. Ranges vary depending on the species, water depth and temperature, sea conditions and can be anything from a few miles to many hundreds of miles




In the Southern US, DolphinEar is used to monitor manatee vocalisations and boat movements that have caused serious injuries to these slow swimming creatures.  In Canada, arrays of DolphinEar hydrophones are used to study the habitat of various fish species within small bays and inlets. And, of course, DolphinEar is widely used in the study of cetaceans around the world.  It’s also a favorite of students, university researchers and dedicated hobbyists




DolphinEar hydrophones have been used by several companies in the Oil industry to identify problems that threatened the stability of drilling platforms. In one case, a hurricane in the Gulf of Mexico damaged a drilling platform. Over the course of several days the three legs of the platform became flooded and began to tip the entire structure. Despite their best efforts the engineers were unable to locate the leaks which threatened the platform. Three 100 metre long DolphinEar PRO




Vision is the primary human sense – we are creatures of ‘light’. Yet the majority of the planet’s inhabitants are creatures of ‘sound’. Equipping students with a unique listening device like the DolphinEar DE200 allows them to discover a new world for themselves. It gives them first hand knowledge, stimulates the amazement of discovery, and develops the curiosity and imagination that is necessary if they are to excel in their chosen careers




Chris Watson, who has worked on David Attenborough’s Frozen Planet and Life in the Undergrowth, shares a remarkable insight into sound recording … I love that aspect of fishing for sound underwater or putting geophones or hydrophones in glaciers, or underground” says Watson





Several years ago, well known Scottish artist Katie Paterson came to us looking for help on a new project. She wanted to listen to the sound of a melting glacier and let people experience these sounds in real time.- as it happened.  We built a custom DolphinEar wireless system to make that project a reality and people from over 130 countries dialed into it from their home and mobile phones to hear the sounds of a melting glacier with their own ears.




Our hydrophones are used by major Film, TV, Audio and Broadcast companies around the world. If you listen to BBC nature series, Discovery Channel, National Geographic you’ve probably heard a DolphinEar in action. They are being used by experimental vocalists, music producers and entertainers. The list goes on. Here are a few examples of how one TV engineer has been using them to cover some unique events




Do you need help with a special or interesting project? Over the years our team has helped to develop solutions for scientists and artists alike. How do you monitor the melting of a glacier in Iceland? And let the entire world listen as it happens?  Or, how do you flicker the lights on a pier in England in sync with real time lightning strikes thousands of miles away? These are two on many projects which our team have designed and developed solutions. Not everything we do involves hydrophones!




Crew and guests are always impressed when they can hear as well as see whales and dolphins. However, in most cases, we can hear them long before they are sighted. There are, of course, many other sounds generated by all kinds of sea creatures and amphibious animals. Go to our ‘Listen’ pages to hear a few of them


Hundreds of fish species (soniferous fish) have been identified by the sounds they make. In fact, it is likely that all fish with swim bladders make some sort of sound either to attract mates or warn off competitors. DolphinEar can help to identify specific habitats and thereby assist in keeping those areas safe and free from pollution and debris. And, noise. Manmade sounds can affect fish behaviour and reproduction whether in the sea, rivers, or inland bodies of water




Whether it’s perimeter or gate security, or monitoring a swimming pool in the dead of night someone is using a DolphinEar right now to solve a problem. So if you are charged with keeping out intruders or preventing accidents then look at some unique solutions using our DolphinEar hydrophones





Watching a TV documentary about wildlife is not the same as experiencing it firsthand. How many times have you walked or driven past a small pond? Have you ever explored it? Have your children? Ponds are incredible living environmental systems. They can provide hours of fascination that lead to amazing professional careers later in life.  Explore them. Sit down and spend some time listening to the life within the pond




The reality of climate change is hard to communicate. It has been done largely in scientific terms with numbers, charts and graphs. Until recently with the extreme weather events that have occurred worldwide, our direct experience with climate change has been limited. Even now there are questions in the minds of many as to how real it is and how reliable are the warnings of scientists.  We have evidence of the extreme changes occurring in the Arctic  and Greenland regions. One worry is
