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 ...

Determining the "loudest recorded sound" depends on how you define sound and on which measurements you choose to include.

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Lower-pitched sounds travel more slowly on Mars than higher-pitched ones, according to new data from NASA's Perseverance rover. When you purchase through links on our site, we may earn an affiliate ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can be ...

Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. Rotons are an exception: their speed of sound changes significantly with the wavelength, it is also ...

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...
