For centuries poets and writers have imagined the depths of the ocean as eerily quiet. But scientists now know that the oceans, and especially coastal areas, are full of sound from both natural and ...

Given how poorly light and radio signals are able to travel underwater, sound is still the best medium for wireless undersea communications. Conventional underwater microphones - or hydrophones - have ...

A research team has successfully recorded the sound of methane bubbles from the seafloor off the Oregon coast, opening the door to using acoustics to identify -- and perhaps quantify -- this important ...

Studying the deep ocean can present a lot of challenges for researchers, but combining different forms of technology can help ...

Eric Martin listened to the sounds of the underwater world using a contraption he pieced together with Tupperware and plastic piping. The water can be a noisy place, especially with the roaring engine ...

How does a submarine talk to an airplane? It sounds like a bad joke but it’s actually a difficult engineering challenge. Traditionally the submarine must surface or get shallow enough to deploy a ...

Pando is the largest organism on Earth, consisting of about 40,000 genetically identical trees. Sound designer Jeff Rice recorded what this organism's vast root system sounds like in a rainstorm. The ...

Ultrasonic measurement systems rely on hydrophones to convert acoustic pressure fields into electrical signals for applications ranging from medical diagnostics and high-intensity therapeutic ...

"We are able to flawlessly communicate and hear between the boats," said NIOT director Balaji Ramakrishnan, confirming the clarity achieved over long horizontal distances. "We wanted to understand the ...
