How to determine the spatial position of a sound source using a pair of microphones?

Question

Sensors

Given : an ordinary school board / whiteboard hanging on the wall, and 2-3 microphones installed next to the board on the same wall.
Task : with high accuracy (+/- 2-3 cm) determine the coordinates of the point at which a conditional object "arrives" (for example, a plastic ball).
Question : in which direction to dig? Are there any ready-made tools / algorithms for processing such information and converting it into coordinates for further transfer to their application?
