Without sound, our lives would not only be very quiet, but we would also lose information about each other and the world around us. We are born with and quickly develop the ability to exchange information and ideas through natural spoken language carried by sound waves over short distances in the air. Animals, both above and beneath the ocean surface, communicate by sound that can travel for tremendous distances. Animals also use sound to probe the world around them: for localization, navigation, and other purposes. In this talk, we explore how humans use sound to communicate beneath the ocean surface, where Wi-Fi and cellular phones don't work. We too can probe our environment with sound to measure distances, locate objects, and even make images of the inside of the human body using ultrasound. We will demonstrate the basic mechanisms of sound as a means both to communicate and to discover information.
