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