Consider, for your listening pleasure, the next frontier in sonic miracles: so-called “audible enclaves,” where only you can hear a sound without disturbing anyone else in open space — no headphones ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...

The bleeding edge: Imagine listening to music or a podcast without headphones while not disturbing others or having a private conversation in a crowded place with the assurance that only the intended ...

The fabric can suppress sound by generating sound waves that interfere with an unwanted noise to cancel it out (as seen in figure C) or by being held still to suppress vibrations that are key to the ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...

In holographic direct sound printing, a transducer emits high-acoustic pressure sound waves, inducing a sonochemical reaction called cavitation that creates solid material inside the build chamber. A ...

Researchers at the Massachusetts Institute of Technology stumbled onto what one called a “very radical” discovery — the new material they had created, akin to silk, could function much in the way a ...

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 ...
