Research, Development, and Calibration Activities

Abstract

To study acoustic wave propagation in both the near and far fields of a radiator to ascertain whether the far-field characteristics of a transducer can be determined from near-field measurements, and to analyze practical methods for using near-field measurements to evaluate far-field performance of transducers.
