1. A directional microphone comprising a plurality of layers, each layer comprising an array of fibers oriented in a respective plane, the fibers of each array of fibers being oriented perpendicular to a respective direction of sensitivity, wherein respective layers among the plurality of layers are spaced from each other to allow free movement of the fibers, and wherein the plurality of layers includes at least a first layer stacked in parallel with a second layer, wherein the first layer comprises fibers oriented in a first direction and the second layer comprises fibers oriented in a second direction different than the first direction such that i) the fibers of the first layer are oriented at an angle with respect to the fibers of the second layer and ii) the respective direction of sensitivity of the first layer is at the angle with respect to the respective direction of sensitivity of the second layer.
