Abstract: 1. A torpedo detecting device of the character disclosed comprising, in combination, a plurality of microphone units, means including orientation means for providing each of said units with a vertically arranged substantially dumbbell-shaped response pattern to a sound signal received thereby from a torpedo moving transversely with respect thereto, and coupling means for spacing said units with respect to each other in such a manner as to provide an overlapping of the response patterns of adjacent units and a substantially uniform longitudinal field of response to sound signals received from a torpedo passing any pair of adjacent microphone units at any point therebetween.
