Claim 21:
22. The method of claim 1 wherein the microphone array includes a first pair of microphones and a second pair of microphones, the first pair of microphones being mounted on a first side of the plurality of sides, the second pair of microphones being mounted on a second side of the plurality of sides, the method further including:
determining a first intensity difference based on the at least one sound signal across the first pair of microphones at a first time;
determining a second intensity difference based on the at least one sound signal across the second pair of microphones at the first time;
determining a third intensity difference based on the at least one sound signal across the first pair of microphones at a second time;
determining a fourth intensity difference based on the at least one sound signal across the second pair of microphones at the second time;
estimating at least one of a speed of travel and a direction of travel of the sound source based on the first intensity difference, the second intensity difference, the third intensity difference, and the fourth intensity difference; and
estimating at least one of a time and a destination at which the vehicle and the sound source will cross paths based on the at least one of the speed of travel and the direction of travel.
