They then played 1,590Hz sound waves from the speaker array to glide the ball through a pre-planned path while microphones detected feedback known as a scattering matrix as it bounced off the ball.

The students had just broken the sound barrier — with a ping-pong ball. “This has been a true engineering project,” said Kristine Lang, chair of CC’s physics department.

There aren’t too many sports named for the sound that is produced during the game. Even though it’s properly referred to as “table tennis” by serious practitioners, ping pon… ...

It blasts the ping-pong ball outward at 900 mph (the speed of sound is roughly 765 mph). French explains how it's done in a video posted here. (At around 5:50 you can see the ball blast through a ...

Manufacturers work to perfect the sound drivers make when the ball is hit just right. Scott Simon talks with Tom Mase, who teaches mechanical engineering at California Polytechnic State University.

Solid ball larger than a ping pong ball but half the weight was levitated with sound April 7, 2017 August 12, 2016 by Brian Wang Researchers demonstrated that acoustic levitation can levitate ...

We took a sound level meter and measured the sound produced by 10 strikes of pickleball and paddle, and 10 strikes of a tennis ball and racquet. The sound level meter picked up slightly louder ...
