<p>PROBLEM TO BE SOLVED: To provide an underwater sound measuring sensor of high performance which can obtain not only the magnitude and the frequency component of a sound in water but the propagating direction of sound wave. SOLUTION: In this underwater sound measuring sensor, at least three or more sensor elements are provided on the same horizontal plane, the sensor elements are not arranged on one straight line, and hence they are arranged on the three apexes of a horizontal triangle. Otherwise, at least three or more sensor elements are provided on the same vertial plane, the sensor elements are not arranged on one straight line, and hence they are arranged on the three apexes 3a, 3b, 3c of a vertical triangle.</p> |
