Underwater Electroacoustic Measurements

This is the authoritative reference on transducer measurements. In this one volume, the book treats both the theory and the practice of measuring electroacoustic transducer parameters: response, sensitivity, directivity, impedance, efficiency, linearity, and noise limits. The advantages and disadvantages of far field and near field measurement techniques are discussed. Calibration and testing of transducers used as measurement instruments are detailed. Finally, Underwater Electroacoustic Measurements addresses the techniques for measuring insertion loss, echo reduction and attenuation of materials auxiliary in nature to transducers such as acoustic windows, reflectors, baffles and absorbers.

This book was written by Robert J. Bobber, Superintendent of the Navy Underwater Sound Reference Laboratory from 1967 to 1980. Although this book is long in the tooth, the fundamentals it tells us of are as valid today as when Bobber first wrote them. Fundamentals don’t go out of style — they are as good as gold.
