ABSTRACT:
A method and system for automatically adjusting a sensitivity of an acoustic detector. The method comprises receiving an acoustic signal from a remote device, detecting the unique pattern embedded therein, changing a mode of operation based upon the detection, measuring a voltage created by the reception of the acoustic signal and adjusting the sensitivity of the acoustic detector based upon a measured voltage. The acoustic signal contains a unique pattern indicative of the remote device.
