Researchers develop an innovative sound wave sensor to quickly and accurately detect elusive helium gas leaks, enhancing ...

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

At University College London, Lesley sings I Dreamed a Dream inside an MRI scanner to reveal how her vocal tract acts as a ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

The film explores the origins of sound through three primary sources: vibrating columns of air, vibrating surfaces, and vibrating strings. It demonstrates how sound is produced by examining a tuning ...

A new sensor detects helium leaks by monitoring how sound waves propagate through a topological material – no chemical ...

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...

A team of researchers from the Ministry of Health in Kuwait has successfully demonstrated the destruction of SARS-CoV-2 virus ...

Scientists at ETH Zurich and the Swiss Federal Institute of Technology Lausanne have developed a device that directs sound waves in one direction without wasting energy. This breakthrough sound wave ...

Create a focused speaker so your music targets only the listener. That demodulates at 40 kilohertz, with an H-bridge and ...

The channel’s latest video demonstrates a gun that shoots a narrow beam of soundwaves, along with its most striking property: ...
