Abstract
One aspect of the invention is a system for locating an object. The system may include, for example, an object electromagnetic receiver, an audio amplifier, an audio transducer, and an object microprocessor coupled to the object electromagnetic receiver and the audio amplifier. The object microprocessor is configured to ascertain whether a valid activation signal has been received by the object electromagnetic receiver, and if so, read a digital sound file, and ascertain whether the signal strength of the received valid activation signal is above a first threshold. If the signal strength is not above the first threshold, the object microprocessor outputs a maximum sound level indicator signal; and if the signal strength is above the first threshold, the object microprocessor outputs a second tier sound level indicator signal.
