A research team in Shanghai has unveiled a vibration-damping technology that could significantly improve the stealth of ...

The Prairie-Masker noise reduction system isn't well-known among civilians but has played a vital role on military vessels for some time. So what does it do?

A Shanghai-based research team has developed a vibration-damping technology that significantly enhances submarine stealth, ...

Researchers say they have developed a way to dampen the underwater vibrations that can be picked up by sonar systems ...

Also, SOUS is a passive listening system for detecting low-frequency submarine noise over long distances, which introduces a lot of unwanted raw data that is of no tactical value. Anduril's Seabed ...

a submarine will produce an effect known as cavitation. Basically, cavitation is what happens when a propeller rotates quickly enough to produce bubbles. Those bubbles then generate a noise when ...

A new report offers a rare look at the conditions in China's growing submarine fleet. It found the crews suffer from excessive noise, poor lighting and bad air quality. The question is whether ...

Submarines use echo-fighting coatings and tiles on their hulls to absorb and scatter sound waves, making subs invisible to enemy vessels. These coatings and tiles also absorb noise from the ...
