A tunable zone detection approach makes use of multiple microphones in a fixed configuration in an environment. There are multiple zones in the environment and one or more predetermined positions in each zone. Predetermined transfer functions between the positions and the microphones are used to determine beamformed energies for each of the positions based on received microphone signals. These beamformed energies may be computed using normalization of correlations between microphones. The beamformed energies are processed using a tunable transformation to determine whether an acoustic source is in a particular zone, thereby enabling adjustment of the detection approach to situations including variation in acoustics of the environment.
A method for acoustic processing in an environment in which a plurality of microphones is in a fixed configuration that provides a plurality of microphone signals sensing the environment, the environment having a fixed predetermined plurality of positions and a plurality of predetermined zones with each zone having one of more of said positions located within it, wherein the acoustic processing includes detecting of an acoustic source in a predetermined zone of the environment, the detecting of the acoustic source comprising:
