Determining bearings acoustically. - The parent Specification describes a switching system by means of which sound detectors located in groups on either side of a ship can be connected to earpieces or receivers in various combinations so as to permit of (1) using two detectors on one side of the ship as a base for binaural direction finding, and (2) using one detector on the port side in conjunction with one on the starboard side for direction finding by the shadow method. The present invention relates to a system which permits of the above combinations and also of combinations for use in the interference method, whereby the vibrations or telephone currents due to two port or two starboard detectors are made to reinforce or to oppose one another in their effect on the ear of the observer so as to produce a maximum or minimum of sound, time-lag or compensating devices being employed to bring about coincidence or opposition of phase. Two or more detectors on opposite sides of the strip can also be grouped together when listening for the mere presence or absence of a sound. The drawings comprise two circuit diagrams showing two methods of obtaining the above result and the Specification contains a table showing settings of the various switches for each of a number of cases. Only two detectors on each side of the ship are required; they can be connected separately or in pairs or groups to one or more of the telephone receivers, transformers and switches making it possible to reverse the phase of any telephone current. Adjustable inductances and capacities can be inserted for adjusting the phases.
