An apparatus implements directional sound detection. The apparatus includes a portable hearing aid device, a plurality of sound detectors, and electronic circuitry. The sound detectors are coupled to the portable hearing aid device. The sound detectors are arranged in a substantially planar array which is located in approximately a two-dimensional plane which extends through both a listener position and a sound generator position. The electronic circuitry is electronically coupled to the plurality of sound detectors. The electronic circuitry generates a reproduced sound signal based on sound signals from at least a subset of the plurality of sound detectors. The subset includes at least two sound detectors in a one-dimensional line and at least one sound detector located within the two-dimensional plane other than along the one-dimensional line.
