Investigators pulled a 1960s Buick sedan from the waterway in central Minnesota that provides new details about a man’s ...

In the picture above, Fang is holding a cloak made with rings of acoustic circuits. The rings were designed to hide underwater objects from sound waves such as sonar or ultrasound.

By essentially turning down the pitch of sound waves, engineering researchers have devised a way to unlock greater amounts of data from acoustic fields than ever before.

Sonar Sound navigation and ranging, or sonar, is one way to find one’s way through the ocean because sound waves travel further than light waves underwater.

1. A new invisibility cloak for sound could help doctors find tiny tumors or hide submarines from enemy sonar. “Our focus is not about dampening noise, but to guide sound waves around structures,” ...

Sound shield: An acoustic cloak comprising alternating layers of sound-scattering materials should make objects invisible to sonar–and insulated from sound. In this computer-generated image, a ...

Engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.

On the day the strandings began, several Navy ships conducted submarine-hunting exercises off North Carolina’s Outer Banks, using loudspeakers to send mid-frequency sonar sound waves across ten ...

An app that uses sonar to detect opioid overdoses is making the leap from research to startup mode with the formation of a new company called Sound Life Sciences. The Second Chance app, announced ...
