By adapting cosmic black holes physics, acoustic engineers have created a device that swallows sound inside pipes to ...

A comprehensive review in Advanced Science unifies the physics of acoustic radiation forces and streaming to explain how ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

Sound wave scattering can be increased in one frequency range only by reducing scattering in another range, according to experiments—a discovery relevant for acoustic engineering. Acoustic guinea pigs ...

Black holes famously trap light. A new acoustic device borrows the idea to swallow sound. (Yukterez/Wikimedia Commons, CC BY-SA 4.0) Sound can be a tricksy beast to try to harness. It fills the world ...

Introduction]When 'ultrasound' (high-frequency sound waves inaudible to humans) is irradiated into a container filled with ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

A recently discovered acoustic effect allows a hot gas to simulate the gravity-induced convection within a star or giant planet. On the rise. Signs of convection are seen in the motion of hot gas ...
