To verify their solution, the researchers simulated the propagation of sound waves in a nonlinear medium similar to ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...

From ETH Zurich: “Schematics of the experimental set-up (left) and wave propagation (right): Waveguide 1 can be heard perfectly by waveguide 3, but not by waveguide 2, and waveguide 3 can be ...

Sound waves travel through different types of matter, including liquid water. ... Macroscopic C₅₄₀ model offers new way to study sound wave propagation in topological metamaterials.

Mesoscale eddies can affect how sound waves propagate in the ocean, depending on their size, speed, current direction and location. Understanding these effects are critical for accurate underwater ...

Sound and other waves usually propagate equally forwards and backwards. Researchers have now developed a method that prevents sound waves from travelling backwards without deteriorating their ...

The Institute of Atmospheric Physics develops and operates advanced sound propagation models. In combination with meteorological mesoscale and microscale models they describe the system of atmosphere, ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE.. See: SOUND, SPEED OF SOUND.Compare: ACOUSTIC RADIATION. The levels of outdoor NOISE, whether they are intrusive or the normal ...

Macroscopic C₅₄₀ model offers new way to study sound wave propagation in topological metamaterials. Researchers have taken a novel approach to studying the interaction between certain ...
