Learn about sound—the waves it travels in, and how the human body creates and hears it—with this blended lesson.

Bat sounds reveal bat secrets
Bats are difficult to track, but by recording their calls, researchers hope to study them.
Why are certain small bodies of water called 'sounds?'
Before doing any reporting on Currituck Sound, I had to answer the most basic of questions: just what is a sound?
It turns out there are a couple of ways to define a sound.
One type of sound is a relatively narrow passage of water between the mainland and an island. It's also an inlet, bay or recessed portion of the ocean. Currituck Sound certainly fits those definitions. So does Pamlico Sound, as well as Puget Sound in Washington.
Secrets of Currituck Sound
Scientists launch the first study of the unique Currituck Sound’s water quality, habitats and wildlife.
Through the Ocean Noise
Sound is something you might not think about when it comes to the ocean. But sound plays a key role in understanding the ocean, and the diverse life that call it home. Marine animals use sound to navigate, communicate, find food, find mates and even avoid predators.
Blackbeard the Wave Glider
To our ears, the sound of being underwater is all the same muffled tone. But to East Carolina University scientists, the noise carries all sorts of information about the ocean. Watch as researchers use their acoustic wave glider named Blackbeard to study underwater noise, acoustically tagged fish and environmental conditions in the ocean.
If You Give a Mouse a Cooler
Who says big plastic coolers are just for keeping beer, soft drinks and food cold for tailgating?
Certainly not Dr. Erich Jarvis, who is an associate professor of neurobiology at Duke University. Let me tell you about some real scientific ingenuity!
Dr. Jarvis’ lab in the Bryan Research Building on the Duke campus is lined with rows and rows of blue coolers with white lids. They are the same type of coolers you see all over the place if you walk through the tailgating area at a football game or sitting near picnic tables in parks.
Sensational Singing Mice
Mice are known to squeak, but Duke researchers have discovered male mice can sing at very high frequencies. The male mice use those ultrasonic sounds to woo female mice, and the song can change depending on the context.
The Marvelous Music Machine
An Asheville musician/inventor/entrepreneur develops a device transforming how the acoustic guitar physically makes sounds. Called an acoustic synthesizer, it alters how the strings vibrate, adding nearly 100 new sounds to the instrument.
