Have you ever tried yelling underwater? Not only is it difficult to make the noise, but it is rarely audible to those outside ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...

Determining the "loudest recorded sound" depends on how you define sound and on which measurements you choose to include.

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can be ...

Yun Jing receives funding from NSF. Jiaxin Zhong does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed ...

Finally, someone can hear you scream in space. Sound waves can’t travel through the vacuum of space, but a pair of physicists in Finland have found a sneaky way to transmit sound across the airless ...

Chris Impey receives funding from the National Science Foundation. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...
