Sound direction finding... underwater.

Hi all.

Underwater, it is not simple to discern the direction a sound comes from;  perhaps with the increased propagation speed the brain is unable to 'compute' the differential arrival times to each ear; or by the external ear lobes shaping and directional capabilities in a not-air medium;  or both, or other factors.

What methods would be convenient to evaluate, experiment to find the incoming direction of sound waves underwater ? (~1500m/s)

Would multiple microphones (6?) and timing analysis do it ?  What else comes to your mind ?
