A method of assembling a hydrophone is provided in which the method stacks ceramic rings, delirin washers, and LC-800 washers such that a top edge of a composite stack extends beyond a top of a hydrophone flange. By measuring the voltage on each ceramic ring while an end cap and a socket head cap screw are installed the axial compression of each ceramic ring is quantified thereby, providing an opportunity to equalize the axial compression of each ceramic ring to yield an accurately performing hydrophone.
