Abstract
Directional sound acquisition is obtained by combining directional sensitivities in microphones with signal processing electronics to reduce the effects of noise received from unwanted directions. One or more microphones having directional sensitivity including a minor lobe pointing in the particular direction of interest and a major lobe pointing in a direction other than the particular direction are used. Signal processing circuitry reduces the effect of sound received from directions of a microphone major lobe.
