The Navy has need of a sensitive (air) microphone, located outside the hull of a submarine, which will withstand the hydrostatic pressure of the ocean during submergence, and then perform normally in air after the boat surfaces. The self-noise of the hydrophone and preamplifier must be low enough so that a distant aircraft can be heard. Depending on the desired listening distance, a choice of designs is available.
