A Moment of Science
Water does a much better job than air of conducting sound waves, but that extra conductivity makes it harder, not easier, to tell where a sound comes from.
Sound waves don't just travel in air: they travel through whatever they encounter, including your body.
Despite the fact that they don't communicate through sound, some moths have ears. Find out why on this Moment of Science.
Ever tried conversing under water? Why is it that some words come out fuzzy while other come out perfectly coherent?
In October of 1947, U.S. Air Force Pilot Chuck Yeager became the first person to fly a plane faster than the speed of sound.
Shout "HELLO" between two cliffs and you'll hear echoes as sound waves bounce back and forth. But how do echoes really work? Find out on this Moment of Science.
You probably imagine that your ears are rather passive, but they can play a surprisingly active role too. Learn more on this Moment of Science.
Did you know whispering behind someone's back rather then in front of them is better for secret telling?
