Yes, it is.
See, for example,

P.L. Chu, "Desktop Mic Array for Teleconferencing," Proc.
  ICASSP-95, Vol. 5, pp. 2999-3002, 1995,

M.S. Brandstein, J.E. Adcock, and H.F. Silverman, "A Closed-Form
  Method for Finding Source Locations from Microphone-Array
  Time-Delay Estimates," Proc. ICASSP-95, Vol. 5, pp. 3019-3022, 1995,
