Abstract
An acoustic transducer 1 has a first cylindrical portion 1A and a second hemispherical portion 1B on which a plurality of transducer elements 10a, 10b are arranged. The transducer elements on the cylindrical portion are arranged to have six nearest neighbors. The arrangement may be such that the six transducer elements surrounding a given element describe the vertices of a regular hexagon. The hexagons thus described may be aligned so that two of their sides are parallel to the axis of the cylinder. The elements on the hemispherical portion may be arranged so that some elements have five nearest neighbors and others have six (the neighboring elements describing, for example, the vertices of hexagons and pentagons respectively). An underwater sounding apparatus may be constructed using the transducer.
