Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful ...

Carefully timed sounds can make fluid waves larger in the sleeping brain, giving researchers a new way to study how brain activity and CSF flow are connected.

Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

A century-old trick for tuning musical instruments has been repurposed to power robots that fly, float and steer themselves using nothing but sound waves.

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 ...
