“In space no one can hear you scream.” If space were truly empty—an utter vacuum, devoid of any matter—then yes, the Alien ...

For a sound to be heard you need three things: A vibrating object A material for the sound wave to travel through, such as air (we call this a medium) Something to detect the sound e.g. your ear ...

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 waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can greatly affect how sound waves travel from one point to another.

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.

A new study shows that sound isn’t just heard by the ears. Sound waves altered gene expression and influenced fat cell ...

These acoustic waves travel by compressing and expanding the water, similar to how sound moves through the air. They travel across transoceanic distances at the speed of sound in the water (around ...

But not many know how helium works. Helium is much lighter than air, so sound waves move much faster through the gas. This amplifies the higher frequencies in your voice. The gas sulfur ...

Sound is a form of energy that travels in waves through matter (like air, water, or glass). When you tap the bottle, you create vibrations - rapid back and forth movements - in both the glass and ...

Crucially, the sound waves — specifically, ultrasound waves — used to create the audible enclaves can't be heard along the path they travel and can even be bent to avoid obstacles. Only when ...

On the other hand, their underwater counterparts are sound waves produced by phenomena like earthquakes or volcanic eruptions, sometimes thousands of meters below the surface. These acoustic waves ...
