The fastest possible speed of sound — 22.4 miles per second, nearly twice its speed in air at the Earth's surface — has been calculated for the first time. British researchers found that such speeds ...

A team from Los Alamos National Laboratory was able to use the microphone and a laser to calculate the speed of sound on Mars, and it's surprisingly slow. Share on Facebook (opens in a new window) ...

When we talk about the speed of sound, we usually mean how fast it moves through air. But it can travel much faster through other media, and now scientists at the University of Cambridge and Queen ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. We know ...

A person fires a starting pistol. A distant observer stood 200 metres away (measured using a 20 m tape measure or trundle wheel) records the time between seeing the flash of light from the starting ...

The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. The speed varies with the medium employed (for example, sound waves move faster through water ...

Although sound travels quite fast, it is still possible to measure its speed in air. To do this, you need to measure the time it takes a sound to travel a measured distance. To reduce errors, ...
