1. An apparatus, comprising:

  • a hearing aid input arrangement including a number of sensors each responsive to detected sound to provide a corresponding number of sensor signals, the sensors each having a directional response pattern with a maximum response direction and a minimum response direction that differ in sound response level by at least 3 decibels at a selected frequency, a first axis coincident with the maximum response direction of a first one of the sensors being positioned to intersect a second axis coincident with the maximum response direction of a second one of the sensors at an angle in a range of about 10 degrees through about 180 degrees; and

    a hearing aid processor operable to execute an adaptive beamformer routine with the sensor signals and generate an output signal representative of sound emanating from a selected source.
