Add to ORKGLow-frequency underwater acoustic transducer calibration; reciprocity calibration 20. ABSTRACT (Continue on reverse side If necessary and Identify by block number) A new method for absolute calibration of electroacoustic transducers is described which permits low frequency reciprocity calibration in a test apparatus of small dimensions. The method takes advantage of the reduced wave speed in a cylindrical water column bounded by a compliant PVC tube to reduce the length of the standing wave to dimensions which can be easily handled in the laboratory.
