A multiple angular sector sound system for receiving sound waves having, in combination, a plurality of adjacent sets of stacked pluralities of arrays of sound-to-electric energy transducers, each array of a set comprising a line of plurality of successive transducers, the successive line arrays of each set of arrays being stacked one upon another in a direction normal to said array lines and with successive array lines twisted at successive angles to the preceding array line to define an angular sector over the set of arrays with each successive array line corresponding to successive angles within that sector, each set being oriented with respect to an adjacent set to define an adjacent angular sector, and means for switching successive line arrays of successive sets of arrays successively to common receiving means responsive to the electric energy transduced thereby, such that the output of the receiving means provides successive electrical signals corresponding to the sound received by the successive arrays along successive angles over the successive scanned angular sectors.
A multiple angular sector sound receiving system having, in combination with a plurality of arrays of sound-to-electric energy transducers in which each array comprises a line of a plurality of successive transducers, means for switching successive line arrays successively to common receiving means, cathode-ray-tube display means provided with means for scanning a display area corresponding to and synchronously with the switching of the successive arrays, the display means being connected with and responsive to the receiving means to indicate upon the display area the sound received by the arrays and in angular orientations corresponding to the angles of reception by the arrays, the display means being provided with a substantially spirally deflected electron beam display having means for intensity-modulating the electron beam in response to the output of said receiving means, each array being connected with an individual integrating circuit means for storing as a d.c. level any signal received thereby, each integrating circuit being connected to a corresponding normally ineffective switching means, and means for rendering the plurality of switching means corresponding to the plurality of arrays successively effective to transmit the stored d.c. level information from the successive integrating circuit means to amplifying means in the said common receiving means, said amplifying means being connected with the said display intensity-modulating means.
