The government received a number of comments both for and against driver-selectable low-speed EV sounds. Vehicles capable of operating silently are required by law to emit sounds at speeds up to 19 ...

Scientists from Queen Mary University of London, the University of Cambridge, and the Institute for High Pressure Physics in Troitsk have discovered the fastest possible speed of sound. The upper ...

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 ...

You probably know that vehicles that can operate solely under electric power have a low-speed warning sound that it projects to let pedestrians – particularly blind or vision-impaired pedestrians – ...

Using a microphone, a laser, and some crafty mathematics, a team of scientists has measured the speed of sound on Mars, in what is a scientific first and another cool finding made possible by NASA’s ...

On Mars, the speed of sound depends on its pitch. All sound travels slower through Mars’ air compared with Earth’s. But the higher-pitched clacks of a laser zapping rocks travels slightly faster in ...
