Scientists have always been curious about sounds and how they travel, or propagate. Underwater acoustics is the study of sounds moving through water, a phenomenon first noted over 2,000 years ago by Aristotle. Since these early beginnings, the science of underwater acoustics has grown to include research ranging from basic sound propagation to using sound for tasks such as mapping surfaces, measuring distances, and communicating. The following sections will lead you through the development of underwater acoustics as a formal science up through World War II (WWII) and the astounding discoveries that have been made during that journey. One interesting post-WWII development, the SOund SUrveillance System, is also included here. The History of the SOFAR Channel is described in another section of the DOSITS website.
