Abstract
An acoustic device captures sound using two or more microphones and filters the sound into a plurality of sub-bands. For each of the plurality of sub-bands, the device identifies sound captured by the microphones from at least two directions and attenuates the sound captured by the microphones, within each of the sub-bands, in substantially one of the directions.
