Claim:
1. A method comprising: receiving sound signals from two or more microphones, wherein the two or more microphones are affixed on the exterior of a helmet; processing the received sound signals to determine a direction of arrival associated with a sound source with respect to the helmet; placing a virtual speaker according to the determined direction of arrival of the sound source, wherein the placing is performed so as to imprint a spatial hearing cue associated with the virtual speaker placement, which spatial hearing cue would be affected by the presence of the helmet; and outputting sound from the virtual speaker, wherein the outputting step is performed by rendering the sound from the virtual speaker to left and right channels associated with physical left and right speakers adjacent to ear locations with respect to the helmet, and wherein the spatial hearing cue is provided by manipulation of an aspect of the spectrum of the sound source in the left and right channels due to the placing of the virtual speaker, respectively.
