Abstract

The sensitivity of a hydrophone in the frequency band when there is a source of reflections which increases the characteristic size of the hydrophone is considered. The effect of the width of the frequency band on the change in the characteristic size is investigated. It is shown that the characteristic size of the hydrophone may be reduced considerably and that far-field conditions can be ensured for measurements in a hydroacoustic basin when it is calibrated in 1/3-octave frequency bands.
