As he watched the Boston Celtics play from the stands of TD Garden, one noise kept catching Adel Djellouli's ear. “This squeaking sound ...

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and ...

A newly published patent proposes a single-sided ultrasonic levitation printer that maintains contactless deposition even when obstacles and conveyors disturb the sound field. Acoustic manipulation ...

Abstract: Acoustic levitation permits non-contact particle manipulation. The position and orientation of the levitated particle can be controlled by altering the acoustic field. Existing acoustic ...

Forward-looking: When wildfires sweep through the dry hills outside Los Angeles, homes can be lost in moments. A California startup imagines a different outcome: as embers fall and nearby brush ...

Austrian scientists working to perfect acoustic levitation have broken through a critical barrier by using electrical charges, allowing them to lift several objects simultaneously while maintaining ...

Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and ...
