trumpet the sound from the trumpet comes from a vibrating column of air created by buzzing lips of the trumpeter A sound wave is a longitudinal wave. When an object vibrates it produces a ...

Focused ultrasound, a non-invasive therapeutic technology first explored in the 1940s, has opened new possibilities for ...

Glaciologists used sound waves to reveal Ice Age landforms buried beneath almost 1 km of mud in the North Sea. The results suggest that the landforms were produced about 1 million years ago, when an ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could ...

Currently, dark matter detection requires specialized laboratories with costly equipment. ODIN, which combines principles of ...

Scientists have found a clever new way of measuring ocean warming, using sound waves from undersea earthquakes. The researchers say the "hack" works because sound travels faster in warmer water.

By containing the sound wave on the surface of a chip ... a postdoctoral researcher in the Institute of Photonics and Optical ...

The device makes sound waves scatter around an object making it invisible to sonar detection. In order to achieve this, the researchers used a "smart" material with special properties. The ...
