Underwater acoustics is a very rewarding field in which to work, one reason being that the frontiers of knowledge are closer at hand than in some other fields. It has not developed as quickly as radar, for example, although the first measurement of the velocity of sound in water was made in 1827.Building on a foundation of physics, underwater acoustics embraces ultrasonics, electrical engineering and mechanical engineering, and impinges on a wide range of subjects such as biology, geology, oceanography and civil engineering. There are also important applications in the fishing industry. Interwoven with all these is the fascination of the sea and of marine life.In this paper, several aspects are considered and some of the results of recent research and development are described. |
