Teaching acoustics at the graduate level to professional naval officers, who, after graduation, will go back to driving ships, submarines, and airplanes, as well as other professional naval disciplines, offers a unique challenge. The Naval Postgraduate School has been the home for over 50 years of the textbook, Fundamentals of Acoustics, originally written by Lawrence Kinsler and Austin Frey and revised in later editions by Alan Coppens and James Sanders. Updating a textbook that is suitable for undergraduate and graduate students in a multitude of disciplines at civilian institutions and also suitable for use by naval officers interested in underwater acoustics continues to be most challenging. Solutions to these and other teaching responsibilities in these environments, including long distance learning, are discussed.
