Abstract:

The use of explosion waves in the relative calibration of a hydrophone offers a new method of approach to the problem of response measurement. Application of this method to two standard hydrophones in the frequently range 5-100 kc gives a relative calibration which agrees with the relative calibration obtained by conventional continuous wave methods. The method may be applied to the calibration of projectors and other linear underwater sound transducers. More rapid analysis of the data is possible through the use of appropriate mechanical or harmonic analyzers, the use of explosion waves is not Restriction to necessary as the method is applicable with any transient. electrical
