The Philosophy of Technology
Sonar Technology and Shifts in Environmental Ethics
For a philosopher, the history of sonar technology is fascinating. During the first and second World Wars, sonar technology was primarily associated with activity on the part of the sonar technicians and researchers. Usually this activity is concerned with creation of sound waves under water, as in the classic “ping and echo”. The last fifteen years have seen a shift toward passive, ambient noise “acoustic daylight imaging” sonar. Along with this shift a new relationship has begun between sonar technicians and environmental ethics.
