With advanced technology and artificial intelligence, we are now able to listen to these cosmic whispers in ways that were once not possible.

Researchers at ETH Zurich have managed to make sound ... wave entering through the second waveguide cannot exit "backwards" ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small ... circumstances and can only be carried out over extremely small distances.

Sound doesn’t just help us hear music or communicate underwater—it can also be used to move objects without physically ...

There just aren’t enough particles to bump into each other to transport the acoustic wave. If you want sound to move through space, you need a much louder source that operates over vast volumes.

Simulation experiments were also performed assuming flat-bottomed terrain, which may also affect sound wave travel. "Future work will explore the effects of dipole eddies on acoustic propagation ...
