Although movie and game producers can now create computer-animated images of just about anything, the sounds made by those onscreen items still typically consist of recordings of real-world objects.

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...

Tractor beams have hit the big time. A newly constructed device generates a beam of concentrated sound that, for the first time, exerts a continuous, perceptible tug on objects large enough to see.

Powerful, carefully controlled sound waves could be used to control objects without having to touch them at all–even inside the human body. This video shows a real live tractor beam in action. It uses ...

Smart glasses that emit a sound when an object comes into their field of view could help people who are blind to locate certain items. Some people who are blind can be trained to move via echolocation ...
