Engineering Acoustics Workshop on the Accuracy of Calibrating Underwater Sound Transducers

Abstract

Measurement accuracy in the calibration, test, or evaluation of underwater sound transducers is a somewhat neglected subject. It is the purpose of this workshop to shed some light on the subject and the reasons for its neglect. A panel of four, representing three naval laboratories and an observer of European laboratories will address several questions. What do the laboratories claim for accuracy? What is meant by “accuracy”? What is the claim based on? Can more accurate measurements be made? What would it cost? Is there a need or demand for more accuracy? After a ten-minute informal presentation by each panel member, the floor will be open for comment and contributions by others who perform measurements, use the data, or are otherwise interested in the subject. Representatives of several industrial and university, as well as naval, organizations have been invited to comment. The panel members are: Joseph Blue, Underwater Sound Reference Division, Naval Research Laboratory, Orlando, Florida; Charles Green, Naval Undersea Center, San Diego, California; Joseph Navin, Naval Underwater Systems Center, New London, Connecticut; W. James Trott, Acoustics Division, Naval Research Laboratory, Washington, D. C., and Chairman, Working Group on Hydrophones, International Electrotechnical Commission Technical Committee on Ultrasonics.
