But until recently, no one was sure that sound waves could carry this type of angular momentum. Even assuming they could, we had no idea how to generate a sound wave with angular momentum.

Bottling up sound waves: Acoustic bottle beams hold promise for imaging, cloaking, levitation and more. ScienceDaily. Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2014 / 08 ...

Scientists project sound waves through a patterned plate known as an acoustic hologram, which is often 3D-printed and computer-designed. It shapes the sound waves in an intricate, predefined way ...

Waste heat from the stove produced during food preparation is used power the acoustic engine, producing sound waves in excess of 170 decibels (more than the Space Shuttle taking off).

Sound waves are used in many imaging applications, but they're often underpowered and hard to focus. But focus them into "sound bullets" and all sorts of interesting things happen. A paper ...

Although still a part of many fantasy flicks and magicians’ routines, levitation is no longer just an illusion. Researchers have been experimenting with using ultrasonic sound waves—well past ...

The acoustic waves are in the ultrasound range — too high-pitched for the human ear to hear, but very loud, blasting at about 160 decibels, where 120 dB is the limit for human hearing, said ...

Normally, sound waves travel in straight lines unless something blocks or reflects them. However, by using acoustic metasurfaces – specialized materials that manipulate sound waves – we can ...
