1. A system for alerting an individual to a specific alert condition, comprising:
- an alert mechanism for monitoring for the specific alert condition and adapted to trigger in response thereto;
a code generator adapted for generating a repeating sequence of two or more pseudo-random acoustic signal pulses when triggered by the alert mechanism; and
a receiving system comprising a microphone for receiving the sequence of pseudo-random acoustic signal pulses, a microprocessor utilizing software for recognizing the sequence of pseudo-random acoustic signal pulses, and a communication means for responding to the recognized sequence of pseudo-random acoustic signal pulses.
