Acoustics is the branch of science that studies the propagation of sound and vibrational waves. Audible acoustic waves are ubiquitous in our everyday experience: they form the basis of verbal human ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

In a recent study, Yale researchers developed a new technology that transmits sound in one direction. In partnership with speaker hire. Researchers in the Yale physics department were able to restrict ...

Wave sounds pro 2.0 Review;The advantages of wireless headsets continue to attract consumers’ attention. The most obvious difference between the two types is the biggest benefit of wireless headphones ...

Midge Costin’s inspiring and educational documentary “Making Waves: The Art of Cinematic Sound” seems destined to wind up in the curriculum of film schools across the country. In a short but ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...
