TRANSDUCER CALIBRATION FROM NEAR-FIELD DATA

Abstract

The theory for obtaining free-field sensitivities and transmitting responses of line or piston-type transducers from near-field data and the equations for obtaining the directivity, transmitting or receiving, from near- field data are derived. The set-up and adjustment of the type CF4 Fourier Integral Computer for computing the data are described and the data that must be obtained are listed.
