Some peoples use the "time-reversal" acoustical concept for localisation
(search for Fink). You may also check for beam forming and steering with
microphone arrays, there is lot of stuff on this from the Japan published in
IEEE Transactions on audio, speech and signal processing (it sound like this,
even if the journal had changed his name so many times over the years).

Good luck,
